Intravascular angioleiomyoma is a rare, benign soft tissue growth that starts in the wall of a blood vessel. It often appears as a small lump under the skin, and many people with intravascular angioleiomyoma notice pain or tenderness, especially in an arm or leg. Early symptoms of intravascular angioleiomyoma can be subtle, and the lump often grows slowly over months or years before it is checked. Not everyone will have the same experience. This condition is most often diagnosed in adults, it is usually not life-threatening, and treatment is usually surgery to remove the growth.
How many people live with Intravascular angioleiomyoma?
Worldwide, there is no reliable estimate for how many people live with intravascular angioleiomyoma, because this very rare condition has mostly been described in individual published case reports rather than large population studies. The same is true in the United States, so no trustworthy national estimate is consistently reported.
Overview
Intravascular angioleiomyomaSymptoms
Intravascular angioleiomyoma often causes a small, firm lump under the skin that can be tender or sharply painful, especially when pressed. Many people notice swelling nearby, while some have no symptoms until it is found on imaging or after removal.
Outlook and prognosis
Intravascular angioleiomyoma is usually a benign growth, and the outlook is generally very good after treatment. Most people do well once it is removed. Recurrence is uncommon, though follow-up may be advised if symptoms return.
Causes and risk factors
Intravascular angioleiomyoma usually develops sporadically, and its exact cause is often unclear. It may relate to smooth muscle growth in a vein wall, with possible links to local injury, hormonal influences, and middle adulthood, especially in women.
Genetic influences
Genetics do not seem to play a major role in intravascular angioleiomyoma. Most cases are thought to happen sporadically, and inherited genetic variations have not been clearly linked to developing intravascular angioleiomyoma.
Diagnosis
Intravascular angioleiomyoma is usually diagnosed after a doctor examines the lump and reviews imaging, often ultrasound or MRI. The diagnosis of intravascular angioleiomyoma is confirmed by removing the growth and checking the tissue under a microscope.
Treatment and drugs
Intravascular angioleiomyoma is usually treated with surgery to remove the painful lump and confirm the diagnosis. Most people do well after complete removal. Follow-up may be advised if the growth was deep, hard to remove, or returns.
Symptoms
Many people with intravascular angioleiomyoma first notice a small lump that hurts when pressed or bumped. The pain may be sharp, aching, or come and go, and some growths are painless. Symptoms vary from person to person and can change over time. Because the early symptoms of intravascular angioleiomyoma can resemble a cyst, a vein problem, or another benign lump, medical review is often needed.
Many people notice a small lump just under the skin, often in the leg or foot. It may feel firm, rounded, and easy to locate with your fingers.
Pain is the most common symptom of intravascular angioleiomyoma. It can feel aching, sharp, or stabbing, and it may be constant or come and go.
The area is often very tender when pressed, rubbed by clothing, or bumped. Even light contact can trigger discomfort for some people.
Pain may flare when the area gets cold or during cooler weather. For many, this can mean outdoor walks or air-conditioned rooms feel more uncomfortable.
How people usually first notice Intravascular angioleiomyoma?
People usually first notice intravascular angioleiomyoma as a small, firm lump under the skin that has been there for a while and may slowly become easier to feel over time. For many, the first warning sign is pain or tenderness that seems out of proportion to the size of the lump, sometimes coming and going and sometimes getting worse with pressure, movement, or changes in temperature. Because it often grows slowly and can look harmless at first, many living with this condition only seek care when the area starts to hurt, becomes more noticeable, or does not go away.
Types of Intravascular angioleiomyoma
Intravascular angioleiomyoma is a rare benign growth that develops from smooth muscle in the wall of a blood vessel. In day-to-day life, the main differences usually come from where the lump is, how big it is, and whether it causes pain or tenderness, rather than from separate disease variants. At this time, no widely accepted, well-defined types of intravascular angioleiomyoma are used in routine patient care.
No recognized types
No distinct types of intravascular angioleiomyoma are widely recognized. Doctors usually describe these tumors by their location, size, and microscope appearance instead of by separate clinical variants.
Can I slow down the onset of symptoms?
Probably not. For intravascular angioleiomyoma, which is a rare, noncancerous growth in the wall of a blood vessel, there is no good evidence that lifestyle changes or medical treatment can meaningfully delay when symptoms begin, and there are no standard screening tests or preventive medicines for people without symptoms. The most helpful step is to get a new painful lump or ongoing tenderness checked early, because even though this does not prevent the condition, it can help people living with it get answers and treatment sooner.
What genetics can tell you about symptoms
For intravascular angioleiomyoma, genetics usually cannot tell you much about which symptoms someone will have. This is a rare, benign growth that is generally thought to happen sporadically rather than being passed down in families, and there are no well-established gene changes that reliably predict when it starts, how painful it will be, or how severe symptoms become. In most people living with this condition, symptoms depend much more on where the growth is and how large it is, such as a small tender lump near a blood vessel causing pain with pressure or movement.
Causes and risk factors
The exact causes and risk factors for intravascular angioleiomyoma are not fully clear. It seems to start when smooth muscle cells in the wall of a blood vessel grow into a small benign lump. It is more often reported in adults, and some studies suggest female hormones or prior local injury may play a part. Family history is usually not part of the story, and inherited gene changes are not a well-established cause. That said, risk is only part of the story, and no clear lifestyle risks like diet, exercise, or smoking have been firmly linked to intravascular angioleiomyoma.
What are the most common causes or risk factors?
The exact cause of intravascular angioleiomyoma, a rare noncancerous growth that forms inside a blood vessel, is not known. It seems to happen when muscle cells in the wall of a vein start growing into a small lump, and it is usually not thought to be passed down in families. It has been reported more often in adults, especially women, and sometimes after local irritation or an injury, but strong, clear risk factors have not been firmly proven.
Environmental and biological risk factors
Intravascular angioleiomyoma is a very rare benign growth that starts from smooth muscle in the wall of a blood vessel, usually a vein. Because it is so uncommon, the known risk factors for intravascular angioleiomyoma are not as clear as they are for more common lumps. Doctors often group risks into internal (biological) and external (environmental). Most links below are patterns seen in reported cases rather than firm causes.
Most cases are reported in adults, often during middle age rather than childhood. This suggests age-related changes in vessel walls and smooth muscle may play a part.
Many reported cases are in women, which suggests sex-related biological differences may influence risk. This pattern does not mean intravascular angioleiomyoma is common in women, only that it appears more often in case reports.
Some of these tumors appear to respond to hormones such as estrogen or progesterone. That makes hormone-related tissue signaling a possible biological factor, although it is not a proven cause.
Intravascular angioleiomyoma usually grows from the muscle layer of a vein, so local abnormalities in the vessel wall are considered an important biological setting. Changes in blood flow or pressure in a small area may also contribute, but this is not fully understood.
Genetic risk factors
If you are told you have intravascular angioleiomyoma, it is natural to wonder whether it runs in families. Right now, no clear inherited cause has been proven, and most cases appear to happen sporadically. Risk is not destiny—it varies widely between individuals. For many people with intravascular angioleiomyoma, routine inherited genetic testing is not usually needed unless the personal or family history points to another condition.
Sporadic pattern: Most intravascular angioleiomyoma cases seem to arise as isolated tumors rather than an inherited condition. This usually means there is no known gene change being passed down through a family.
Family history: A family history of intravascular angioleiomyoma is not a well-established genetic risk factor. Most people diagnosed do not have relatives with the same rare tumor.
Inherited syndromes: Intravascular angioleiomyoma has not been clearly linked to a common inherited syndrome. Unlike some other smooth muscle growths, it is not usually managed as part of a known hereditary tumor disorder.
Somatic changes: The tumor may result from DNA changes that develop only in the affected tissue during life. These tissue-only changes are different from inherited changes present from birth and are not known to be passed to children.
Testing decisions: Genetic testing is not routinely recommended for a single, typical intravascular angioleiomyoma because the genetic risk factors for intravascular angioleiomyoma are still unclear. Testing may be considered if there are multiple unusual tumors or a strong family history that suggests another inherited condition.
Lifestyle risk factors
Current evidence does not show clear lifestyle risk factors for intravascular angioleiomyoma. This benign soft-tissue tumor is not known to be caused by diet, exercise habits, or other everyday behaviors. When people ask about lifestyle risk factors for intravascular angioleiomyoma, the most accurate answer is that proven modifiable causes have not been established, although certain habits can affect symptoms, recovery, or how quickly a lesion is assessed.
No specific dietary pattern has been shown to cause intravascular angioleiomyoma. Eating habits may influence overall vascular and surgical health, but they are not established drivers of this tumor.
Regular exercise is not known to increase the risk of developing intravascular angioleiomyoma. However, repeated use or pressure on the affected area can make pain or tenderness more noticeable in some people who already have a lesion.
Smoking has not been identified as a direct cause of intravascular angioleiomyoma. It can still impair circulation and wound healing, which may matter if the tumor is painful, being monitored, or removed surgically.
Alcohol has no proven role in causing intravascular angioleiomyoma. Heavy use may still complicate recovery and interact with pain control or perioperative care if treatment is needed.
Risk prevention
Intravascular angioleiomyoma is a rare, noncancerous growth that develops from the muscle layer of a blood vessel, often in the arms or legs. There is no proven way to fully prevent intravascular angioleiomyoma because it is not clearly linked to everyday habits in the way many common diseases are. Prevention is flexible—it adapts to your life and health background. In practice, the best approach is lowering avoidable strain on blood vessels, paying attention to new lumps or pain, and getting medical care early if symptoms appear.
There is no established method that reliably prevents intravascular angioleiomyoma from forming. That means risk reduction focuses more on early attention to symptoms and protecting overall blood vessel health than on a specific preventive treatment.
If you notice a small tender lump under the skin, especially in a leg or arm, have it checked rather than waiting months for it to settle. Early review of possible early symptoms of intravascular angioleiomyoma can speed diagnosis and treatment if needed.
Avoiding smoking and managing blood pressure, cholesterol, and blood sugar may support healthier blood vessels overall. These steps have not been proven to stop intravascular angioleiomyoma, but they can reduce other vessel problems that may complicate care.
Repeated bumps, pressure, or strain in the same area may irritate soft tissues and blood vessels, so practical protection at work, during sports, or with tight footwear can help. This is not a guaranteed way to prevent intravascular angioleiomyoma, but it is a sensible way to reduce avoidable local stress.
Can you prevent Intravascular angioleiomyoma?
There is no known way to prevent intravascular angioleiomyoma, a rare noncancerous growth that forms in or around a blood vessel. It is not clearly linked to lifestyle habits, so things like diet, exercise, or other routine health choices have not been proven to stop it from developing. If you notice a new lump or unexplained pain, having it checked early can help with diagnosis and treatment, even though it does not prevent the growth itself.
Transmission
If you are worried about catching intravascular angioleiomyoma from someone else, the reassuring news is that you cannot. Intravascular angioleiomyoma is not an infection, so it does not spread through the air, close contact, sex, food, water, or blood.
Many living with intravascular angioleiomyoma also wonder how intravascular angioleiomyoma is inherited, but this condition is usually considered sporadic rather than something passed from parent to child in a clear pattern. In other words, it is not considered contagious, and it is not known for predictable family transmission.
When to test your genes
For intravascular angioleiomyoma, genetic testing is not routinely recommended because this is usually a benign, non-inherited tumor. Care is guided by the lump’s size, location, imaging, and biopsy results. Testing may be considered only if you also have a strong family history or other unusual tumors suggesting an inherited syndrome.
Diagnosis
Many people with intravascular angioleiomyoma first seek care for a small lump that is painful, tender, or bothersome with pressure or movement. Because this tumor is rare and can look like other soft tissue or vein-related growths, the diagnosis of intravascular angioleiomyoma often starts with symptoms, an exam, and imaging. Doctors usually begin by checking the size, location, firmness, and whether the mass seems attached to a vein or nearby tissue.
Your doctor will ask when the lump appeared, whether it has grown, and if it causes pain, tenderness, or sensitivity with touch. They also look at where it sits, since these tumors often appear as a small, well-defined mass under the skin.
During the exam, the mass is checked for size, mobility, firmness, and whether pressing on it reproduces pain. The overlying skin and nearby circulation are also assessed to help separate it from more common causes of a painful lump.
Ultrasound is often one of the first imaging tests because it can show whether the lump is solid and whether blood flow is present within or around it. This can suggest a vascular tumor, but ultrasound alone usually cannot confirm exactly which kind it is.
MRI can give a clearer picture of the mass and its relationship to nearby veins, muscles, and soft tissues. This is especially helpful in how intravascular angioleiomyoma is diagnosed when the lump is deeper, larger, or not clearly defined on exam.
How is Intravascular angioleiomyoma diagnosed?
Doctors usually suspect intravascular angioleiomyoma after hearing about a small, slow-growing lump, often one that hurts or is tender, and examining it; an ultrasound or MRI scan can help show that the growth is connected to a blood vessel. The diagnosis is usually confirmed only after the lump is removed, or sometimes sampled, and looked at under a microscope to show a noncancerous growth made of muscle cells in the wall of a blood vessel. Genetic testing is not usually part of diagnosing this condition.
Stages of Intravascular angioleiomyoma
Intravascular angioleiomyoma does not have defined progression stages. This is because it is usually a small benign growth that is identified as a lump or painful spot, rather than an illness that predictably moves from one stage to the next over time. Often the process begins when you notice changes in daily life, such as a tender bump that hurts when pressed or starts to catch your attention during walking or dressing. Doctors usually diagnose intravascular angioleiomyoma by examining the lump, using imaging such as ultrasound or MRI when needed, and confirming it after removal under a microscope; the early symptoms of intravascular angioleiomyoma can overlap with other soft tissue lumps, so follow-up depends on what the exam and test results show.
Outlook and prognosis
The outlook for people with intravascular angioleiomyoma is excellent, because it is a benign tumor and complete surgical removal is usually curative. Recurrence is uncommon and is most often related to incomplete excision rather than aggressive behavior. Symptoms such as localized pain or tenderness generally improve after treatment, and long-term function is typically preserved. Malignant transformation has not been established as a typical feature of this lesion, although careful pathologic review is important to distinguish it from other vascular or smooth-muscle tumors. Mortality from intravascular angioleiomyoma is not expected, and deaths attributable to the tumor itself have not been reported as a usual outcome. Continued follow-up may be advised in selected cases, especially if the lesion was large, anatomically complex, or not fully removed.
Long-term effects
For many people, intravascular angioleiomyoma mainly has a local, long-term effect rather than a whole-body one. The biggest ongoing issue is often a small painful lump that can interfere with walking, standing, or using the affected area, especially if it sits in the foot, leg, or hand. After treatment, the outlook is usually very good, and serious complications are uncommon. Thinking about the long-term effects helps set expectations: most relate to pain, function, and the small chance that the growth comes back.
Intravascular angioleiomyoma can cause lasting tenderness or sharp, intermittent pain, sometimes made worse by pressure, movement, or cold temperatures. Many living with intravascular angioleiomyoma notice that even a small lump can become very bothersome in daily life.
If the growth is in a weight-bearing or frequently used area, it may make walking, exercise, or repetitive hand use uncomfortable over time. This is one reason early symptoms of intravascular angioleiomyoma are sometimes mistaken for a minor soft-tissue injury.
Some people have a persistent small mass, mild swelling, or a sense of fullness in one spot. Long-term effects vary widely, but these local features usually stay limited to the area where the tumor is growing.
When intravascular angioleiomyoma is removed, long-term problems are uncommon, but some may have a scar, temporary soreness, or lingering sensitivity near the surgical site. Most people recover well once the lesion is fully excised.
How is it to live with Intravascular angioleiomyoma?
Living with intravascular angioleiomyoma often means dealing with a small, usually slow-growing lump that may be tender or painful, especially when it is pressed, bumped, or located where movement keeps irritating it. For many people, daily life is mostly affected by local discomfort rather than illness throughout the body, but pain or worry about what the lump might be can make walking, exercise, work, or sleep more stressful until it is properly evaluated and, in many cases, removed. The people around you may notice that you avoid pressure on that area or feel anxious about a new mass, but this is a benign tumor and it is not contagious, so the main effect on family and friends is usually practical and emotional support rather than any direct health risk to them.
Treatment and drugs
Intravascular angioleiomyoma is usually treated by surgically removing the growth, because this kind of tumor is benign but can still cause pain, tenderness, or a small lump that gets in the way of daily comfort. For many, this means a planned procedure to take out the whole mass and confirm the diagnosis under a microscope, which is often the most effective treatment. Treatment often looks different for each person, but medicines are generally used only to help with symptoms such as pain rather than to shrink the tumor itself. After removal, most people do well, and the chance of the tumor coming back is low when it has been fully taken out. If you are wondering about the best treatment for intravascular angioleiomyoma, your doctor may also recommend follow-up visits to check healing and make sure symptoms have improved.
Can you cure Intravascular angioleiomyoma?
Yes, in most cases intravascular angioleiomyoma can be cured by surgery to fully remove the growth. It is a rare noncancerous lump, and once it has been completely taken out, symptoms usually go away and it usually does not come back.
Non-drug treatment
Daily life with intravascular angioleiomyoma often centers on a small lump that can be tender, especially when pressed or bumped. Because this growth is usually benign, treatment depends mostly on how much pain, discomfort, or worry it causes and where it sits in the body. Not every approach works the same way, and many people with intravascular angioleiomyoma do well with monitoring, while others need a procedure to remove it.
If the lump is small, stable, and not causing much trouble, careful observation may be enough. This usually means checking for changes in size, pain, or how often it gets irritated.
Surgery is the main non-drug treatment for painful or bothersome intravascular angioleiomyoma. Removing the lump usually confirms the diagnosis and often relieves symptoms at the same time.
Ultrasound or MRI can help show the lump's size, depth, and relationship to nearby blood vessels before treatment. This can be especially useful when planning surgery for intravascular angioleiomyoma in a sensitive area.
Simple routines-like avoiding repeated pressure on the area or protecting it from knocks-can lessen day-to-day discomfort. For many, this means changing how they sit, cross their legs, carry bags, or exercise until treatment is complete.
Your genes may have an impact on how drugs work for you
For people with intravascular angioleiomyoma, treatment is usually a procedure to remove the lump rather than long-term medicine, so genetic differences are not known to play a major role in how this condition is treated. If medicine is used, it is usually for short-term pain relief or around the time of surgery, and there are no widely accepted gene-based recommendations that are specific to this condition. In other words, unlike some illnesses where genes can help guide drug choice, that is not a well-established part of care for intravascular angioleiomyoma.
Pharmacological treatments
With intravascular angioleiomyoma, medicines usually do not remove the growth itself. In practice, drug treatment is mostly about easing pain, helping around a procedure, or supporting recovery after surgical removal, which is the usual treatment. If one medicine doesn’t help, that doesn’t mean treatment has failed, because the main goal of medication here is symptom control rather than cure. People looking up early symptoms of intravascular angioleiomyoma may also want to know that pain can come and go, so the choice of medicine often depends on how often it flares and whether surgery is planned.
Acetaminophen can help relieve mild pain from intravascular angioleiomyoma. It does not shrink the mass, but it may make day-to-day discomfort easier to manage.
Ibuprofen or naproxen may be used when pain seems linked to pressure or irritation around the lesion. These drugs can reduce pain and inflammation, but they should be used carefully in people with stomach ulcers, kidney disease, or bleeding risks.
Local numbing medicines such as lidocaine may be used during evaluation, biopsy, or surgical removal. These drugs help control procedure-related pain rather than treating the tumor itself.
After surgery, doctors may use acetaminophen, NSAIDs, or sometimes a short course of an opioid if pain is stronger. Sometimes medicines are taken short-term for recovery, while the surgery itself is what treats intravascular angioleiomyoma.
Genetic influences
Because intravascular angioleiomyoma is usually a one-time, localized growth, many people are most concerned about whether it could affect other family members. It’s natural to ask whether family history plays a role. For intravascular angioleiomyoma, current evidence suggests genetics are not a major or clearly established cause, and this tumor is not known to commonly run in families. When people ask whether intravascular angioleiomyoma runs in families, the best current answer is usually no. Most cases seem to happen sporadically, meaning the growth develops in one blood vessel rather than from an inherited gene change. Because of that, genetic testing is not usually part of routine care unless there are other unusual findings, such as several related tumors or a strong family history of similar smooth muscle growths.
Is Intravascular angioleiomyoma genetic?
Genetics do not seem to play a major role in intravascular angioleiomyoma. Most cases are thought to happen sporadically, and inherited genetic variations have not been clearly linked to developing intravascular angioleiomyoma.
Having a genetic risk is not necessarily a diagnosis
Genetic variants are a usual part of being human and are common throughout the general population. Most do not directly affect health and are simply part of normal human variation. In many genes, having a variant connected with a condition suggests a possible link rather than a definite diagnosis, especially when several genes and environmental factors are involved. In some cases, though, one well-understood variant in a particular gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For most people with intravascular angioleiomyoma, treatment is mainly surgery, so genetics usually does not have a big role in choosing a disease-specific medicine. There are no well-established genetic tests that guide treatment for intravascular angioleiomyoma itself, and there is no standard drug therapy tailored to inherited gene changes for this tumor.
Not every difference in response is genetic, but some may find that pain medicine, anti-nausea medicine, or anesthesia used around surgery works differently from one person to another because of common gene differences that affect how the body handles drugs. This usually matters more for comfort and safety during the procedure than for treating the growth itself. If you are preparing for treatment for intravascular angioleiomyoma and have had unusual medication side effects in the past, letting your care team know can help them choose and dose medicines more carefully. As research grows, genetics may help explain why these tumors develop in some people, but right now it has only a limited role in the treatment of intravascular angioleiomyoma.
Interactions with other conditions
People living with intravascular angioleiomyoma usually notice a small, localized lump or pain rather than body-wide illness, and this condition is not known to have strong, consistent links with common chronic diseases. Another important aspect is how it may link with other diseases: intravascular angioleiomyoma can look similar to problems such as a blood clot in a vein, a vascular malformation, varicose vein disease, or other soft-tissue growths, so careful imaging and sometimes a biopsy are needed to tell them apart. For many, this can mean the condition is first worked up because of swelling, tenderness, or a mass that raises concern for something more common or more serious. Unlike aggressive cancers, intravascular angioleiomyoma is considered benign, and there is no well-established evidence that it regularly triggers other diseases or spreads to distant organs. Still, if doctors are evaluating the early symptoms of intravascular angioleiomyoma, they will often also check for nearby vein problems or other tumors that can cause similar day-to-day symptoms.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Intravascular angioleiomyoma?
Other causes of a small painful lump, especially in an arm or leg, can include a blood vessel growth such as a hemangioma or venous malformation, a ganglion cyst near a joint, a nerve-related lump, or even a blood clot in a vein if there is swelling and tenderness. It can also be mistaken for other common soft-tissue lumps such as a lipoma, and less often doctors may need to rule out a soft-tissue cancer if the lump is growing quickly or looks unusual on a scan.
History
People living with intravascular angioleiomyoma are often dealing with something that seems puzzling at first: a small lump, often painful or tender, that may have been present for a long time before it is identified. In everyday life, this can mean noticing a firm spot under the skin that hurts when pressed, or a bump in the leg or foot that seems minor but keeps drawing attention because of discomfort.
This condition entered medical practice through reports of unusual smooth-muscle growths linked to blood vessel walls. Initially understood only through symptoms, later doctors were able to recognize a more specific pattern under the microscope and separate intravascular angioleiomyoma from other soft tissue lumps. Earlier case reports often described it as a vascular or smooth-muscle tumor found in adults, especially in the limbs, but the exact naming and classification became clearer over time.
As medical science evolved, pathologists improved the way these growths were grouped. That mattered because intravascular angioleiomyoma can look like several other harmless or, more rarely, more serious masses before it is removed and examined. Not every early description was complete, yet together they helped doctors understand that this is usually a benign growth arising in close relationship with a vein, rather than a cancer spreading through the body.
In more recent decades, better imaging and more careful tissue analysis have made diagnosis more accurate. Many living with intravascular angioleiomyoma still do not get an answer until after surgery, because the early symptoms of intravascular angioleiomyoma can be nonspecific and overlap with other common causes of a painful lump. Knowing this history helps explain why the condition may still be unfamiliar to many people, even though it has been described in medical reports for many years.
