Glomeruloid hemangioma is a rare skin growth made up of small blood vessels, and it most often appears in adults. It usually shows up as red, purple, or blue raised bumps on the skin, so early signs of glomeruloid hemangioma may look like unusual new spots that do not go away. Glomeruloid hemangioma itself is usually benign and not a common direct cause of death. It may help to know that doctors have studied this condition for decades, and glomeruloid hemangioma can be an important clue to an underlying disorder called POEMS syndrome. Treatment often focuses on the related condition, and individual skin lesions may sometimes be removed or treated if they cause symptoms or cosmetic concerns.
How many people live with Glomeruloid hemangioma?
Glomeruloid hemangioma, a very rare blood-vessel skin growth, does not have a reliable published count for how many people are living with it worldwide. In the United States as well, there is no widely accepted named registry, study, or public health source that reports a trustworthy population estimate for this condition.
Overview
Glomeruloid hemangiomaSymptoms
Glomeruloid hemangioma usually appears as small red, purple, or blue raised spots on the skin. These growths are often painless, but some may bleed easily or become tender if rubbed.
Outlook and prognosis
Glomeruloid hemangioma itself is benign and often stable. For many, the bigger issue is whether it occurs with POEMS syndrome, since outlook then depends on that condition and treatment response. Regular follow-up helps catch changes early.
Causes and risk factors
Glomeruloid hemangioma is usually linked to POEMS syndrome, a rare disorder driven by abnormal plasma cells. Risk is highest in adults with POEMS features or related blood protein abnormalities. No clear lifestyle, environmental, or inherited risk factors are known.
Genetic influences
Genetics do not seem to play a major role in glomeruloid hemangioma. Most cases are not inherited, and no single causative gene is known; when it appears, doctors often focus more on related conditions than on genetic testing.
Diagnosis
Glomeruloid hemangioma is diagnosed by a skin exam and confirmed with a biopsy viewed under a microscope. Doctors may also order blood tests, imaging, and other checks to look for related conditions, especially when considering the diagnosis of glomeruloid hemangioma.
Treatment and drugs
Glomeruloid hemangioma often does not need direct treatment unless the spots bleed, hurt, or bother you. When needed, doctors may remove them with laser treatment or a small procedure, and they usually also look for related conditions such as POEMS syndrome.
Symptoms
Glomeruloid hemangioma usually shows up as small, raised spots on the skin rather than causing strong physical symptoms. You might notice small changes at first, such as a red, purple, or blue bump that does not go away. Many people with glomeruloid hemangioma feel no pain, which is why the early symptoms of glomeruloid hemangioma are often easy to overlook. These spots matter because, in some people, they can be a clue to an underlying condition such as POEMS syndrome.
The most common change is one or more small, firm bumps on the skin. They are often rounded and can become more noticeable slowly over time.
These spots are usually red, purple, or blue because they contain many tiny blood vessels. They may look darker than a pimple or mole and usually do not fade away on their own.
Many glomeruloid hemangiomas do not hurt or itch at all. Some may feel mildly tender or irritated, especially if clothing rubs the area.
Because these spots are rich in blood vessels, they can bleed after scratching, shaving, or another small injury. The bleeding is usually minor but can be annoying if the spot is bumped often.
How people usually first notice Glomeruloid hemangioma?
People usually first notice glomeruloid hemangioma as one or more small, dome-shaped red, purple, or blue skin bumps that slowly appear on the trunk, arms, legs, or face and do not go away like a simple rash. These spots are usually painless, though some may bleed if rubbed or injured, and a doctor often recognizes them as unusual because they can look different from common birthmarks or ordinary cherry angiomas. In many living with this condition, the first signs of glomeruloid hemangioma matter because these skin changes can be an early clue to POEMS syndrome, a rare disorder that also affects nerves and other organs, so new unexplained vascular bumps are worth having checked.
Types of Glomeruloid hemangioma
No distinct types of Glomeruloid hemangioma are widely recognized.
Can I slow down the onset of symptoms?
No. For these rare blood-vessel skin growths, called glomeruloid hemangiomas, there is no good evidence that lifestyle changes such as diet, exercise, sleep, or supplements can delay when they appear, and healthy habits have not been shown to prevent them or push back their onset. These spots are often tied to an underlying rare illness rather than day-to-day habits, so the most useful medical step is early evaluation of any new unusual skin bumps or other symptoms so doctors can check for related conditions; while that may not stop the spots from starting, it can help you get the right care sooner.
What genetics can tell you about symptoms
For glomeruloid hemangioma, genetics usually cannot predict which symptoms you will have, how severe they will be, or when they will start. These growths are not known to follow a clear inherited pattern, and they are most often discussed as a skin finding linked to an underlying condition called POEMS syndrome rather than to a specific disease-causing gene change. In practice, symptoms tend to depend more on where the growths are, how many there are, and whether POEMS-related problems are also present.
Causes and risk factors
Glomeruloid hemangioma often appears in people with POEMS syndrome, a rare disorder linked to abnormal plasma cells. The exact cause is not fully understood, and researchers are still learning how these pieces fit together. The main risk factors for glomeruloid hemangioma are biological, especially having POEMS syndrome or a related plasma cell disorder. No inherited genetic change has been proved to directly cause these skin growths in most people. There is also no clear evidence that diet, exercise, smoking, or other everyday environmental exposures directly cause them.
What are the most common causes or risk factors?
The main known risk factor for glomeruloid hemangioma is having POEMS syndrome, a rare illness linked to abnormal blood cells that can affect the nerves, hormones, skin, and other organs. These skin growths are not usually known to be inherited, and no clear lifestyle causes, such as diet, smoking, or everyday exposures, have been proven. They are seen mostly in adults rather than children, but overall this is a very rare condition.
Environmental and biological risk factors
Most of what doctors know about risk factors for glomeruloid hemangioma comes from patterns seen in rare blood-related disorders, not from day-to-day exposures. Doctors often group risks into internal (biological) and external (environmental). For glomeruloid hemangioma, the established risks are almost entirely biological. No clear environmental trigger has been confirmed.
Glomeruloid hemangioma is most strongly linked with POEMS syndrome, a rare disorder involving abnormal plasma cells. When these skin growths appear, doctors often consider POEMS because the two are closely associated.
An abnormal group of plasma cells, often with a monoclonal blood protein, seems to raise the likelihood of glomeruloid hemangioma. This points to an internal blood and immune system problem rather than a skin-level exposure.
High levels of blood-vessel growth signals in the body, especially vascular endothelial growth factor or VEGF, are thought to play an important role. These signals can promote unusual growth of tiny blood vessels in the skin.
Glomeruloid hemangioma is reported mainly in adults, often in middle age, and it is rare in children. Age itself is not a cause, but this pattern suggests the underlying body changes usually develop later in life.
Genetic risk factors
For glomeruloid hemangioma, no inherited gene change has been proven to cause these skin growths on its own. Most cases are linked to POEMS syndrome, a rare illness driven by an acquired problem in plasma cells, which are immune cells that make antibodies. This means the genetic causes of glomeruloid hemangioma are still unclear, and family history is not seen as a major risk factor. Routine genetic testing is usually not used to predict who will develop it unless another inherited condition is also suspected.
No known mutation: No single inherited mutation has been shown to cause glomeruloid hemangioma. In most reported cases, these lesions appear sporadically rather than running in families.
POEMS syndrome: Glomeruloid hemangioma is most strongly associated with POEMS syndrome. When doctors find this lesion, they often consider POEMS because the connection is well established.
Plasma cell change: In many people with POEMS, an abnormal group of plasma cells seems to help drive the process that leads to glomeruloid hemangioma. This is usually an acquired change in blood-forming cells, not a gene variant passed down from a parent.
Family history: Family history is not considered a major genetic risk factor for glomeruloid hemangioma. If several relatives have similar skin findings, doctors may look for another explanation because a clear inherited pattern has not been confirmed.
Lifestyle risk factors
There are no known lifestyle habits that directly cause glomeruloid hemangioma. When people ask about lifestyle risk factors for glomeruloid hemangioma, the more useful question is how lifestyle affects glomeruloid hemangioma, especially irritation, bleeding, healing, and day-to-day symptom burden. Practical habits can matter most when lesions are fragile, repeatedly traumatized, or occur along with a broader condition such as POEMS syndrome.
Repeated rubbing from tight clothing, straps, shaving, or scratching can irritate a glomeruloid hemangioma and make tenderness or surface bleeding more likely. Reducing friction may help limit minor trauma and make the lesion easier to monitor.
Picking at the lesion or exposing it to frequent cuts and bumps can trigger bleeding, crusting, or delayed healing. Protecting the area during sports, grooming, and daily activities may lower these complications.
Smoking does not cause glomeruloid hemangioma, but it can impair circulation and wound healing if a lesion breaks down or is removed. Avoiding tobacco may support better skin recovery and reduce postoperative healing problems.
Heavy alcohol use can worsen dehydration, poor nutrition, and sometimes bleeding tendency, which may complicate care of a fragile vascular lesion. Limiting alcohol may be especially helpful if treatment, biopsy, or repeated skin trauma is a concern.
Risk prevention
There is no proven way to fully prevent glomeruloid hemangioma, because it is a rare blood vessel growth that often appears as part of an underlying condition rather than from everyday habits alone. For many living with glomeruloid hemangioma, prevention is really about catching related health problems early and lowering the chance of complications. Prevention is about lowering risk, not eliminating it completely.
New red, purple, or bluish bumps on the skin should be checked promptly, especially if they are multiplying or changing. Paying attention to early signs of glomeruloid hemangioma can help lead to earlier testing for linked conditions.
Glomeruloid hemangioma is often linked with POEMS syndrome, so doctors may look for nerve symptoms, swelling, hormone problems, or abnormal blood proteins. Finding and treating the underlying disorder may reduce future problems even if it does not stop every skin lesion.
Ongoing visits with a dermatologist or other specialist can help track whether spots stay stable or whether new ones appear. Prevention works best when combined with regular check-ups.
Protecting the skin from repeated friction, picking, or unnecessary trauma may help lower bleeding or irritation from existing lesions. This will not prevent glomeruloid hemangioma itself, but it can reduce day-to-day skin problems.
Can you prevent Glomeruloid hemangioma?
There is no known, proven way to prevent glomeruloid hemangioma, a rare blood vessel growth in the skin, because its exact cause is not fully understood. In some people, it can happen along with another underlying illness, so getting new or unusual skin bumps checked early may help find related health problems sooner, but this has not been shown to stop the growths from forming.
Transmission
Glomeruloid hemangioma is not contagious, so it cannot be passed from one person to another through close contact, sex, coughing, blood, or shared items. For many living with glomeruloid hemangioma, this means family members and partners are not at risk of catching it.
It is also not usually considered an inherited condition, so the genetic transmission of glomeruloid hemangioma is not a typical concern. Instead, these growths usually develop sporadically and are often linked to an underlying medical condition called POEMS syndrome rather than to infection or routine parent-to-child inheritance.
When to test your genes
Genetic testing is not routinely useful for glomeruloid hemangioma because it is not known to be an inherited condition. If this lesion is found, the important next step is medical evaluation for POEMS syndrome and an underlying plasma cell disorder, since that is what guides early detection and treatment.
Diagnosis
Glomeruloid hemangioma is usually diagnosed after a doctor examines a small red, purple, or blue skin bump and looks at a tissue sample under a microscope. Because this growth can be linked with a rare blood and nerve disorder called POEMS syndrome, the workup often checks for more than the skin lesion alone. Getting a diagnosis is often a turning point toward answers and support.
Doctors first look at the size, color, and pattern of the skin lesion and ask when it appeared or changed. This helps them decide whether glomeruloid hemangioma is likely and whether a biopsy is needed.
The main test is a biopsy, where a small piece of the lesion is removed and examined under a microscope. The diagnosis of glomeruloid hemangioma is made by finding a very specific cluster of tiny blood vessels that has a characteristic glomerulus-like pattern.
Blood and urine tests may be done to look for signs of an underlying condition, especially POEMS syndrome. These tests can check for abnormal proteins, hormone changes, and other clues that the skin finding is part of a broader illness.
If there are symptoms such as numbness, tingling, weakness, or burning pain, doctors may perform a nerve exam and sometimes nerve conduction tests. These help look for nerve damage that can occur when glomeruloid hemangioma is linked to POEMS syndrome.
How is Glomeruloid hemangioma diagnosed?
Glomeruloid hemangioma is usually diagnosed by looking closely at the skin growth and confirming it with a biopsy, which means taking a small sample and checking it under a microscope. The microscope pattern is what makes the diagnosis, because these spots can look like other skin growths at first. Since this finding can be linked with a rare body-wide illness called POEMS syndrome, doctors may also order blood tests, scans, and other exams to look for signs of that condition.
Stages of Glomeruloid hemangioma
Glomeruloid hemangioma does not have defined progression stages. This is because it is usually identified as a specific skin growth under the microscope, rather than a condition that predictably moves through step-by-step phases over time. Doctors usually start with a conversation about when the spot appeared, whether it has changed, and whether there are other symptoms such as numbness, swelling, or unexplained weight changes, since these can matter in the diagnosis of glomeruloid hemangioma. Diagnosis is usually confirmed with a skin exam and a biopsy, and follow-up may include checking for related conditions, especially if more than one lesion is present or other body-wide symptoms develop.
Outlook and prognosis
The outlook for glomeruloid hemangioma itself is generally excellent because the skin lesion is benign and does not usually behave aggressively or spread. Prognosis depends largely on whether it occurs as part of POEMS syndrome, where the overall course is driven by the associated plasma cell disorder and the extent of nerve, endocrine, and organ involvement. In people with an isolated lesion, treatment is often local and curative, with low risk of serious complications. Mortality is not expected from the hemangioma alone, but in patients with POEMS syndrome, survival can be reduced if the underlying disease is severe or untreated. Early recognition of a glomeruloid hemangioma can therefore be important because it may prompt evaluation for POEMS syndrome and earlier treatment, which can improve long-term outcomes.
Long-term effects
For many, glomeruloid hemangioma mainly has long-term effects on the skin rather than causing dangerous local damage. These growths often stay for years unless they are treated, and new spots can appear over time. The long-term picture is often shaped less by the skin lesion itself and more by whether it occurs as part of a broader illness such as POEMS syndrome. Because of that, glomeruloid hemangioma prognosis depends a great deal on the underlying cause and on regular medical follow-up.
Glomeruloid hemangioma often remains visible long term if it is not removed or otherwise treated. Some spots stay small, while others slowly enlarge or become more noticeable over time.
Many people living with glomeruloid hemangioma may feel self-conscious if lesions are on the face, trunk, or other easy-to-see areas. This can affect clothing choices, social comfort, or body image even when the spots are medically benign.
These lesions can sometimes rub on clothing, catch during shaving, or become tender after minor trauma. Small episodes of bleeding or crusting may happen, but severe local complications are uncommon.
In some people, glomeruloid hemangioma is not limited to a single spot, and additional lesions may develop over the years. Doctors may track these changes over years to see whether the pattern stays limited to the skin or suggests a related condition.
How is it to live with Glomeruloid hemangioma?
Living with glomeruloid hemangiomas often means living with small, reddish to violaceous skin bumps that may be more noticeable than bothersome, but their real importance is that they can be a clue to a broader condition, most often POEMS syndrome. For many people, daily life is affected less by the skin lesions themselves and more by the symptoms that can travel with the underlying disorder, such as nerve pain, weakness, fatigue, swelling, or trouble with balance, which can make walking, working, and routine tasks harder. Family members and caregivers may also feel the strain, especially if they are helping with appointments, mobility, or day-to-day support, but recognizing these skin changes early can help guide people toward the right evaluation and care.
Treatment and drugs
Treatment for glomeruloid hemangioma depends on whether it is a single skin growth or part of a wider illness, most often POEMS syndrome, a rare disorder that can affect nerves, hormones, and the blood. If the spot is small and not causing problems, doctors may simply monitor it, but bothersome or bleeding lesions can often be removed with a minor procedure such as surgical removal or laser treatment. When glomeruloid hemangioma appears as part of POEMS syndrome, treatment usually focuses on the underlying disease, which may include medicines, radiation, or other therapies chosen by a specialist. Treatment often looks different for each person, and the best plan depends on symptoms, the number of lesions, and whether other organs are involved. If you are looking into treatment for glomeruloid hemangioma, it helps to ask whether care should target the skin lesion itself, the underlying cause, or both.
Can you cure Glomeruloid hemangioma?
Glomeruloid hemangioma can often be treated successfully by removing the skin growth, so an individual spot may be gone for good after treatment. But if it is linked to an underlying illness, treatment also needs to focus on that broader condition, which can help control symptoms and lower the chance of new growths appearing.
Non-drug treatment
Many living with glomeruloid hemangioma do not need treatment for the skin spots themselves unless they bleed, rub on clothing, or cause worry because of how they look. Managing this condition often means looking beyond the skin, since glomeruloid hemangioma can be a clue to an underlying illness such as POEMS syndrome. In day-to-day life, that may mean a dermatology visit for a growing bump on the trunk or a lesion that catches when getting dressed. Because of that, non-drug care usually includes monitoring, skin-focused procedures, and treatment of any related underlying disorder.
Small, stable glomeruloid hemangiomas often do not need immediate treatment. Regular skin checks help track changes in size, color, bleeding, or irritation.
Gentle skin care and avoiding repeated friction can help if a lesion is easily bumped or rubbed by waistbands, bras, or straps. Simple wound care may lower the chance of bleeding or crusting if the surface gets irritated.
A dermatologist may remove a bothersome or often-bleeding lesion with a minor procedure. This can relieve symptoms and also confirm the diagnosis if there is any doubt about the cause of the spot.
Some vascular lasers can shrink or lighten selected lesions, especially when appearance is a major concern or the spot bleeds easily. Not every approach works the same way, so results depend on the size and depth of the lesion.
Your genes may have an impact on how drugs work for you
For people with glomeruloid hemangioma, there is no well-established evidence that inherited gene differences are used to predict how medicines will work, so genetic testing usually does not guide treatment for the skin growth itself. Care is usually based more on where the growth is, whether it causes symptoms, and whether it is part of a broader illness called POEMS syndrome, which can change the treatment plan. In real life, this means two people with similar-looking spots may get different care because of their overall health picture, not because of known drug-response gene changes.
Pharmacological treatments
For many, treatment of glomeruloid hemangioma is really treatment of the underlying condition that often goes with it, especially POEMS syndrome. There is usually no standard pill or cream that reliably removes the skin growths on its own, and many living with glomeruloid hemangioma do best when doctors focus on the related blood-cell disorder instead. Not everyone responds to the same medication in the same way. If you are searching for the best treatment for glomeruloid hemangioma, the answer often depends on whether POEMS syndrome or another linked illness is present.
Small glomeruloid hemangioma spots often do not need medicine if they are not painful, bleeding, or changing quickly. In many cases, doctors monitor them while treating any related disease behind the lesions.
Prednisone or dexamethasone may be used when glomeruloid hemangioma appears as part of POEMS syndrome or a plasma cell disorder. These drugs can calm inflammation and help control the broader illness, but they are not usually a stand-alone cure for the skin lesions.
Melphalan and cyclophosphamide are medicines doctors may use to treat the abnormal plasma cells linked to POEMS syndrome. When that underlying disease improves, glomeruloid hemangioma may also become less active or less noticeable.
Thalidomide, lenalidomide, and bortezomib are commonly used medicines for POEMS syndrome and related plasma cell problems. These drugs do not target glomeruloid hemangioma directly, but they may help by shrinking the disease process driving the skin changes.
Genetic influences
Glomeruloid hemangioma is not usually thought of as an inherited condition passed from parent to child. Instead, it is most often linked with POEMS syndrome, a rare disorder involving abnormal plasma cells, and those cell changes usually happen during life rather than being present at birth. It is natural to ask whether family history plays a role, but most people with glomeruloid hemangioma do not have relatives with the same skin growth. When people ask what causes glomeruloid hemangioma, genetics is usually a smaller part of the picture than the underlying blood disorder and related body-wide changes. If your care team suspects POEMS syndrome, they may look more closely at the abnormal cells with blood, bone marrow, or other lab tests, but that is different from the kind of genetic testing used to look for inherited conditions.
Is Glomeruloid hemangioma genetic?
Genetics do not seem to play a major role in glomeruloid hemangioma. Most cases are not inherited, and no single causative gene is known; when it appears, doctors often focus more on related conditions than on genetic testing.
Having a genetic risk is not necessarily a diagnosis
Changes in genes are a normal part of being human and are common in the general population. Most of these changes do not directly affect health and are simply part of natural human diversity. For many genes, having a change linked to a condition suggests a possible connection rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some cases, though, one well-understood change in a particular gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For many living with glomeruloid hemangioma, the biggest question is whether a skin growth can simply be watched or removed, or whether it points to a wider illness that needs treatment. Not every difference in response is genetic, but glomeruloid hemangioma does not usually have a well-established pharmacogenetic test that tells doctors which drug will work best. When treatment for glomeruloid hemangioma is needed, it is often a procedure such as removal rather than a long-term medicine, so gene-based drug choice is usually not the main issue. If the lesion is linked with a rare blood disorder called POEMS syndrome, doctors focus on treating that underlying condition, and medication choices depend more on the overall disease, organ function, and side effect risks than on genes known to affect the skin lesion itself. In short, genetics can be important in the broader medical picture, but there is currently no routine, widely accepted genetic test used specifically to match drugs to glomeruloid hemangioma.
Interactions with other conditions
Glomeruloid hemangioma often matters less as a skin spot on its own and more because it can be a clue to another illness happening in the body. It is most strongly linked with POEMS syndrome, a rare disorder that can affect nerves, hormones, blood proteins, and other organs, so doctors may look more closely if these growths appear along with numbness, weakness, swelling, or unexplained skin changes. Certain diseases may overlap, meaning a glomeruloid hemangioma can show up alongside conditions such as Castleman disease, which is also sometimes part of the broader POEMS picture. For many living with glomeruloid hemangioma, this can mean the skin finding leads to blood tests, nerve testing, and a wider check for related problems rather than treatment of the spot alone. Interactions can look very different from person to person, and not everyone with glomeruloid hemangioma will have the same associated condition or the same early symptoms of POEMS syndrome. Because of that, it is usually best to have these lesions assessed in the context of your overall health, especially if other symptoms are developing at the same time.
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 Glomeruloid hemangioma?
Glomeruloid hemangiomas can look a lot like other red, purple, or blue skin bumps, especially common blood vessel growths such as cherry angiomas, pyogenic granulomas, and other harmless hemangiomas. Doctors may also want to rule out less common but more serious causes of similar-looking spots, such as Kaposi sarcoma, especially if the bumps are changing quickly, bleeding, or appearing along with other body-wide symptoms.
History
People living with glomeruloid hemangioma usually come across the name after a skin biopsy or a specialist visit, not because it has been widely discussed in everyday health information. The condition entered the medical literature fairly recently, when doctors began describing an unusual type of small blood vessel growth in the skin that looked different from more familiar hemangiomas under the microscope. At first, these reports were based mainly on what pathologists could see in tissue samples, so understanding was limited.
In recent decades, awareness has grown as doctors recognized that glomeruloid hemangioma can sometimes appear alongside broader health problems rather than as an isolated skin finding. That mattered because a bump or cluster of reddish-blue spots on the skin might seem minor at first, but in some people it helped point to a larger condition affecting nerves, hormones, or other body systems. As medical science evolved, descriptions became more precise, and the term glomeruloid hemangioma was used for lesions with a very distinctive microscopic pattern that resembles the tiny filtering units seen in the kidney.
Over time, the way the condition has been understood has changed, with newer studies helping doctors sort out when these skin lesions are most strongly linked to other illnesses and when they may be less specific than once thought. Not every early description was complete, yet together they helped shape today’s view that glomeruloid hemangioma is mainly a diagnostic clue rather than simply a cosmetic skin problem. Knowing this history helps explain why doctors may recommend more than skin treatment alone if early symptoms of glomeruloid hemangioma raise concern for a related underlying disorder.
