Rombo syndrome is a very rare inherited skin condition that usually becomes noticeable in childhood or the teen years. Early signs of Rombo syndrome can include small, pit-like marks on the face, a bluish-red skin pattern, sparse hair on the scalp or eyelashes, and skin that feels dry or fragile. It may help to know that doctors have studied this condition for decades, and not everyone will have the same features. Rombo syndrome is lifelong, and many living with Rombo syndrome need regular skin checks because basal cell skin cancers can develop later, often in adulthood. Treatment focuses on sun protection, routine follow-up with a skin specialist, and prompt treatment of any skin cancers or troublesome skin changes.
How many people live with Rombo syndrome?
Rombo syndrome is so rare that there is no reliable current estimate of how many people are living with it worldwide or in the United States. Published medical reports describe only a very small number of families living with Rombo syndrome, so it is considered exceptionally rare, but there is no established global count or U.S. count.
Overview
Rombo syndromeSymptoms
Rombo syndrome mainly affects the skin. Common features include small widened blood vessels on the face, slow-growing hair, patchy skin color changes, and tiny whitish bumps. Some people later develop skin cancers, especially basal cell carcinoma.
Outlook and prognosis
Many living with Rombo syndrome do well day to day, but lifelong skin changes often continue. The main concern is a higher chance of basal cell skin cancers, so regular dermatology visits and sun protection matter.
Causes and risk factors
Rombo syndrome is caused by a change in one copy of the PSENEN gene, usually inherited from an affected parent. In many families it follows a dominant pattern, though some cases may result from a new genetic change.
Genetic influences
Genetics seem central in Rombo syndrome, which appears to run in families and is often described as likely autosomal dominant. Still, the exact genetic change causing Rombo syndrome has not been firmly confirmed.
Diagnosis
Rombo syndrome is usually suspected from clinical features, especially the skin and facial findings that appear over time. The diagnosis of Rombo syndrome is confirmed with a clinical evaluation, family history, and sometimes genetic tests.
Treatment and drugs
Rombo syndrome is managed with regular dermatology visits and careful daily sun protection. Early treatment of suspicious spots is important because skin cancers can develop. Some people with Rombo syndrome also treat visible blood vessels or facial bumps.
Symptoms
Rombo syndrome mainly affects the skin, hair, and small blood vessels near the skin surface. Many living with Rombo syndrome first notice skin changes in later childhood, and the early features of Rombo syndrome often include a pitted or net-like texture on the face. For many people with Rombo syndrome, these traits stay mild for years, but some skin findings become more noticeable with age. Because this condition can also raise the risk of certain skin cancers later in life, new or changing spots should be checked.
The skin on the cheeks or forehead can develop a fine, uneven pattern that looks shallowly indented or honeycomb-like. In daily life, this may be most noticeable in bright light or in photos, even when the skin does not feel sore.
Small, firm white cysts called milia often appear on the face. They are usually harmless, but many people find them persistent and hard to ignore during daily skin care.
Hair on the scalp, eyebrows, or eyelashes can be thinner than expected. What once felt effortless can start to require more energy or focus, such as managing delicate hair or noticing less eyebrow or eyelash fullness over time.
Some may have a bluish or reddish tint of the skin, especially in cooler temperatures. This happens because small blood vessels near the skin surface are more visible or react differently, and the hands or face may look unusually flushed or dusky.
How people usually first notice Rombo syndrome?
How Rombo syndrome is first noticed is usually through skin changes that begin in childhood, often when families or doctors see a pitted, net-like thinning of the skin on the cheeks called vermiculate atrophoderma, along with very sparse hair or eyelashes and tiny white cysts known as milia. As children grow, some may also develop a bluish or reddish color in the skin of the hands or face because of changes in small blood vessels, and the skin can start to look unusually dry, delicate, or uneven in texture. The first signs of Rombo syndrome are often subtle at first, but over time the pattern of early skin changes helps doctors recognize the condition and monitor for later problems such as skin tumors.
Types of Rombo syndrome
No distinct types of Rombo syndrome are widely recognized.
Can I slow down the onset of symptoms?
No one has shown that lifestyle changes or medicines can meaningfully delay the start of Rombo syndrome, because the early skin and hair changes are part of the condition itself. The one step most doctors strongly advise is careful sun protection, which may lower the risk of the skin cancers that many people with Rombo syndrome can develop later, but it does not prevent the condition or guarantee that symptoms will start later. While there is no proven way to stop it from beginning, paying close attention to new or changing skin spots can still help problems get found and treated early.
What genetics can tell you about symptoms
Genetics can tell us that Rombo syndrome is an inherited condition, and the gene change linked to it helps explain why people develop a recognizable pattern of skin findings over time, including changes in the skin and a higher chance of certain skin cancers. Even within the same family, symptoms can vary, so genetics cannot reliably predict exactly which features someone will have, how severe they will be, or the exact age they will begin. In general, the genetic diagnosis is most helpful for confirming the condition and guiding long-term skin checks, rather than forecasting a precise symptom timeline for one person.
Causes and risk factors
Rombo syndrome usually runs in families and is thought to be passed down in an autosomal dominant way. This means one affected parent can pass the condition to a child. Doctors have not yet found the exact gene change, so the clearest risk factor is a family history of Rombo syndrome. Age and sun exposure can affect how strongly it shows up in people living with Rombo syndrome, especially the later risk of basal cell skin cancers. Knowing your family history is a good first step.
What are the most common causes or risk factors?
The main known risk factor for Rombo syndrome is family history, because it appears to be a very rare inherited condition that can be passed from a parent to a child. The exact gene change has not been clearly pinned down, but the pattern strongly suggests a genetic cause rather than something caused by diet, stress, or everyday habits. There are no well-proven non-genetic causes of the syndrome itself, although too much sun exposure may further raise the risk of the skin cancers that can happen with it.
Environmental and biological risk factors
When people look for risk factors for Rombo syndrome, the main finding is that research is very limited because the condition is so rare. Researchers are still exploring how outside influences interact with our inner biology. So far, no clear environmental or additional biological risk factors for Rombo syndrome have been confirmed.
Maternal age, health problems during pregnancy, and birth complications have not been consistently linked to Rombo syndrome. Because only a small number of cases have been described, doctors cannot point to a proven pregnancy-related risk.
No specific infection, medication, radiation, or chemical exposure has been consistently tied to Rombo syndrome. Current evidence does not support a clear environmental trigger.
Genetic risk factors
For many living with Rombo syndrome, the main risk appears to come from inherited factors. The genetic causes of Rombo syndrome are still not fully understood, because no single confirmed gene has been identified. Reports from affected families suggest an autosomal dominant pattern, which means one affected parent may be enough to pass on the condition. People with the same risk factor can have very different experiences.
Unknown gene: No specific gene has yet been firmly confirmed as the cause of Rombo syndrome. Because of that, genetic testing may not always give a simple yes-or-no answer.
Family history: The condition has been described in families, so having an affected parent or close relative can raise the chance of it appearing in other relatives. This is often the clearest inherited risk doctors look for.
Dominant pattern: Reported families suggest that one changed copy of a gene may be enough to cause the syndrome. When a parent is affected, each child may have about a 1 in 2, or 50%, chance of inheriting that risk.
Variable expression: Even within the same family, signs can start at different ages and vary in severity. One relative may have subtle skin changes, while another develops more obvious features.
Lifestyle risk factors
Rombo syndrome is an inherited skin condition, so lifestyle habits do not cause it. However, how lifestyle affects Rombo syndrome can be important because daily habits may influence skin damage, wound healing, irritation, and the chance of complications such as basal cell carcinoma. The most relevant lifestyle risk factors for Rombo syndrome are those that increase ultraviolet injury, weaken skin care, or delay early treatment of changing lesions.
Ultraviolet exposure can add to the skin fragility and cancer risk already associated with Rombo syndrome. Frequent sunburns, tanning, or long hours outdoors without protection may increase the chance that suspicious skin changes develop or are missed until later.
Indoor tanning delivers concentrated ultraviolet radiation that can further damage skin affected by Rombo syndrome. This may raise concern for earlier or more frequent precancerous changes and basal cell carcinoma.
Smoking can impair blood flow to the skin and reduce normal healing in people with Rombo syndrome. It may worsen skin quality, delay recovery from irritated or injured areas, and complicate treatment after skin procedures.
Repeated picking, harsh scrubbing, squeezing milia, or abrasive cosmetic treatments can irritate already vulnerable skin in Rombo syndrome. This may lead to more inflammation, delayed healing, and greater difficulty tracking new or meaningful skin changes.
Risk prevention
With Rombo syndrome, there is no known way to prevent the condition itself because it is inherited. Prevention mostly means lowering the chance of complications, especially sun-related skin damage and skin cancer, which can become more likely over time. Many living with Rombo syndrome do best with steady skin care, sun protection, and regular follow-up. Prevention is flexible—it adapts to your life and health background.
Daily sun protection is one of the most important ways to lower skin damage in people with Rombo syndrome. Shade, protective clothing, and broad-spectrum sunscreen can help reduce ultraviolet exposure. This matters because Rombo syndrome can raise the risk of basal cell skin cancers over time.
Regular visits with a dermatologist can help find suspicious spots early, before they grow deeper or harder to treat. For many, this can mean full-body skin exams on a schedule that matches personal risk. Early symptoms of skin cancer in Rombo syndrome may be subtle, such as a sore that does not heal or a shiny bump that slowly changes.
Checking your skin at home can help you notice new growths, sores, or changing patches between appointments. A quick monthly look in a mirror, or with help from a family member, can make small changes easier to catch. Photos can also help track spots that seem different over time.
Tanning beds and intentional tanning add extra ultraviolet exposure and should be avoided in Rombo syndrome. Even if you cannot remove all risks, prevention can reduce their impact. This is especially important for skin that may already be more vulnerable to long-term damage.
Can you prevent Rombo syndrome?
Because Rombo syndrome is a rare inherited condition, there is no known way to prevent it. If it runs in your family, meeting with a genetics specialist can help you understand the chances of passing it on. While this cannot stop the syndrome itself, careful sun protection and regular skin checks may help lower the risk of some related skin problems.
Transmission
Rombo syndrome is not contagious, so it cannot be passed from one person to another through touch, coughing, kissing, sex, or shared food. Instead, the genetic transmission of Rombo syndrome appears to happen within families.
In the small number of families described, Rombo syndrome has most often followed an autosomal dominant pattern, which means a parent living with the condition may pass it on to a child. Some people may be the first in their family to have it because of a new genetic change, and because Rombo syndrome is so rare, doctors are still learning exactly how Rombo syndrome is inherited in every case.
When to test your genes
If Rombo syndrome runs in your family, or you have early skin changes such as patchy thinning hair, tiny cysts, or a lace-like sunken rash, ask for a genetics and dermatology evaluation. Because the exact gene is not firmly established, genetic testing is not routine, so regular skin checks are the main tool for early detection and personalized care.
Diagnosis
Rombo syndrome is usually diagnosed by putting together a pattern of skin and hair changes that build over time, rather than from one single test. Early and accurate diagnosis can help you plan ahead with confidence. In many living with Rombo syndrome, doctors look closely at long-standing facial skin changes, sparse hair, and later skin cancers to make the diagnosis. Because this condition is very rare, the diagnosis of Rombo syndrome often involves a skin specialist and sometimes a genetics specialist.
Doctors usually begin with a careful skin and scalp exam to look for the typical combination of small cysts, a net-like or thinned facial skin texture, and reduced hair growth. The diagnosis is often based on this recognizable pattern developing over years rather than on one finding alone.
The age when changes first appeared can be very helpful, since some features often start in childhood and others show up later. Doctors ask how the skin, hair, and any bumps or sores have changed over time to see whether the pattern fits Rombo syndrome.
A detailed family and health history can help show whether similar skin changes or repeated skin cancers have affected close relatives. This matters because Rombo syndrome is thought to run in families, even though the exact genetic cause is not always identified.
A small sample of skin may be taken if the diagnosis is uncertain or if there is a suspicious growth. Looking at the tissue under a microscope can help confirm skin cancer and rule out other rare skin conditions that can look similar.
How is Rombo syndrome diagnosed?
Rombo syndrome is usually diagnosed by a skin specialist who looks for a very specific pattern of changes over time, such as thin or pitted skin on the face, tiny white bumps, sparse hair or eyelashes, and later skin growths, sometimes including a type of skin cancer. The doctor will also ask when these changes began and whether other family members have had similar skin problems, and they may remove a tiny piece of skin to examine it under a microscope to help rule out other conditions. There is no widely used single genetic test that confirms Rombo syndrome, so the diagnosis mainly depends on the medical history and skin exam.
Stages of Rombo syndrome
Rombo syndrome does not have defined progression stages. This is because it is a rare inherited condition that tends to show a pattern of skin and hair changes over time rather than moving through clear medical stages. Often the process begins when you notice changes in daily life, such as very sparse hair, patchy skin color, or skin that becomes unusually delicate and marked by visible tiny blood vessels; later on, doctors also watch for skin cancers that can develop in adulthood, so knowing the early symptoms of Rombo syndrome can help families know what to bring up. Diagnosis is usually based on the pattern of symptoms, a skin exam, family history, and sometimes genetic testing if the diagnosis is uncertain.
Outlook and prognosis
The outlook for people with Rombo syndrome is generally good in terms of overall life expectancy, because the condition usually progresses slowly and does not typically affect major internal organs. The main long-term concern is a markedly increased risk of developing basal cell carcinomas, often beginning in adulthood, so lifelong dermatologic surveillance is important. With regular skin examinations and prompt treatment of suspicious lesions, many complications can be managed effectively and outcomes are usually favorable. Cosmetic skin changes and recurrent skin tumors can still cause substantial chronic burden and may require repeated procedures over time. Mortality is not well defined because the syndrome is extremely rare, but death is not considered a typical direct feature; prognosis depends largely on early detection and management of skin cancers.
Long-term effects
Many living with Rombo syndrome mainly notice long-term changes in the skin and, for some, an increased chance of certain skin cancers over time. Long-term effects vary widely, and not everyone has the same features or the same level of medical concern. In childhood and adolescence, the changes may be subtle, while in adulthood the skin findings often become easier to recognize.
The most important long-term effect of Rombo syndrome is a higher risk of basal cell skin cancers, often beginning in adulthood. These growths tend to appear on sun-exposed skin and may come back more than once over the years.
Many people with Rombo syndrome develop lasting changes such as thin, delicate facial skin, small widened blood vessels, and a bluish-red skin color. These features often become more noticeable with age rather than fading.
Sparse scalp hair, thinning of the eyebrows, or loss of eyelashes can continue long term. For many, this can affect appearance and may become more obvious from the teen years into adulthood.
Some may have reduced sweating, which can persist throughout life. This can make heat feel harder to tolerate, especially during exercise, hot weather, or time in warm indoor spaces.
How is it to live with Rombo syndrome?
Living with Rombo syndrome often means managing visible skin and hair changes that begin over time, including thin or sparse hair, small facial bumps, and skin that may look uneven, delicate, or bluish in cooler temperatures. For many people, daily life includes careful sun protection, regular skin checks, and occasional treatments for skin growths, especially because the condition is linked to a higher risk of basal cell carcinoma, a common type of skin cancer that usually grows slowly when found early. The effects can reach beyond the person living with it, too: family members may help with appointments and monitoring, and the emotional side of having a very rare, noticeable condition can affect confidence, relationships, and how comfortable someone feels in social settings.
Treatment and drugs
There is no cure for Rombo syndrome, so treatment focuses on protecting the skin, watching closely for problems, and treating changes as they appear. Because Rombo syndrome can raise the risk of repeated basal cell skin cancers, many living with it need regular full-body skin checks, careful sun protection, and quick assessment of any new sore, bump, or patch that does not heal. If skin cancer develops, treatment often includes removing it with a procedure such as standard surgery or Mohs surgery, and some smaller spots may be treated with other skin-directed methods depending on where they are and how deep they go. Supportive care can make a real difference in how you feel day to day, and this may include help with dry or fragile skin, advice on gentle skin care, and, when needed, support from a dermatologist and genetics team over time.
Can you cure Rombo syndrome?
No, there is no cure for Rombo syndrome right now. Because it is a lifelong genetic condition, treatment focuses on managing the skin changes, protecting the skin from sun damage, and checking often for skin cancer so any problems can be treated early. This care cannot make the condition go away, but it can help lower risks and manage symptoms.
Non-drug treatment
Living with Rombo syndrome often means paying close attention to skin changes over time, especially on sun-exposed areas. Because this condition can raise the risk of certain skin cancers, non-drug care focuses on protecting the skin, finding problems early, and treating suspicious spots with procedures rather than medicines. For many, treatment begins not at the pharmacy, but with daily habits and regular follow-up with a dermatologist. Care is usually tailored to the skin findings each person has, since Rombo syndrome can vary from one person to another.
Careful sun protection is one of the most important parts of managing Rombo syndrome. This usually means shade, protective clothing, wide-brimmed hats, and broad-spectrum sunscreen to lower UV damage and help prevent new skin cancers.
Regular full-body skin exams help catch early symptoms of Rombo syndrome that are changing, along with possible basal cell cancers, as soon as possible. Many living with Rombo syndrome also benefit from checking their own skin at home and reporting any new bump, sore, or nonhealing spot.
Suspicious or confirmed skin cancers are often treated with procedures such as surgical removal, Mohs surgery, or other dermatologist-led techniques depending on the size and site. Some non-drug options are delivered by specialists, and early treatment can limit tissue damage and improve healing.
Laser therapy may sometimes help visible small blood vessels or certain surface skin changes when they are bothersome. Not every approach works the same way, so a dermatologist can explain whether this is likely to help in Rombo syndrome.
Your genes may have an impact on how drugs work for you
For people with Rombo syndrome, there is no well-established evidence that inherited gene changes clearly affect how most commonly used medicines work, so genetic drug testing is not a routine part of care. Treatment is usually focused on day-to-day needs, such as protecting the skin, checking for skin cancers early, and treating skin problems that come up. This means medicine choices are generally based more on the skin issue being treated, age, and overall health than on the genetic change itself.
Pharmacological treatments
There is no medicine that cures Rombo syndrome or changes its underlying genetic cause. Medication can feel like a big step, but in Rombo syndrome, drugs are mainly used to treat specific problems such as superficial skin cancers or skin irritation rather than the condition as a whole. Because people with Rombo syndrome can develop repeated basal cell skin cancers over time, treatment is usually tailored to the type, size, and location of each lesion.
Imiquimod is a prescription cream that may be used for some small, superficial basal cell skin cancers in people with Rombo syndrome. It works by helping the immune system attack abnormal skin cells. Redness, crusting, and soreness at the treated spot are common during treatment.
5-fluorouracil cream is another topical treatment that may be used for selected very shallow skin cancers or precancerous sun-damaged areas. It is not right for deeper basal cell cancers, so doctors choose it carefully. This can be part of medications for Rombo syndrome when the main goal is treating limited skin lesions.
Vismodegib and sonidegib are oral drugs used for advanced, hard-to-remove, or metastatic basal cell carcinoma. These medicines are not routine first treatment for Rombo syndrome, but they may be considered when surgery or local treatment is not enough. Side effects can include muscle cramps, taste changes, hair loss, and weight loss.
Simple pain medicines such as acetaminophen or ibuprofen may help after procedures used to remove skin cancers or treat irritated lesions. They do not treat Rombo syndrome itself, but they can make recovery easier. Ask your doctor why a specific drug was recommended for you.
Genetic influences
Many living with Rombo syndrome first realize there may be a genetic link when similar skin changes show up in a parent, child, or several relatives across generations. The exact gene causing Rombo syndrome has not been clearly identified, but it is widely thought to be an inherited condition and likely follows an autosomal dominant pattern, which means an affected parent may pass it on to a child. Family history is one of the strongest clues to a genetic influence. Even within the same family, Rombo syndrome can look quite different, with some people having milder early skin changes and others developing more noticeable features or a higher risk of basal cell skin cancer later on. Because the gene has not yet been pinned down, genetic testing for Rombo syndrome is usually not able to give a firm answer, but genetic counseling can still help families understand inheritance and plan regular skin checks.
Is Rombo syndrome genetic?
Genetics seem central in Rombo syndrome, which appears to run in families and is often described as likely autosomal dominant. Still, the exact genetic change causing Rombo syndrome has not been firmly confirmed.
Having a genetic risk is not necessarily a diagnosis
Genetic changes are a normal part of human biology and are widely found in the general population. Most variants do not have a direct effect on health and simply reflect natural differences among people. For many genes, carrying a variant associated with a condition points to a possible link rather than a definite diagnosis, especially when several genes and environmental factors are involved. In some cases, though, a single well-understood variant in a particular gene is enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
For people with Rombo syndrome, treatment usually focuses on regular skin checks, protecting the skin from sun damage, and treating any suspicious growths early. Not every difference in response is genetic, but with Rombo syndrome the inherited nature of the condition mainly helps explain why it can run in families, not which medication will work best. Because the exact genetic cause of Rombo syndrome has not been clearly confirmed, doctors do not currently have a routine gene-based test that guides drug choice for this condition. Instead, treatment is tailored to what is happening in daily life: one person may mainly need support for ongoing skin changes, while another may need prompt treatment for a basal cell skin cancer. If skin cancers develop, the choice of creams, procedures, or surgery depends much more on the type, size, and location of the lesion and on overall health than on known drug-gene interactions. Genetic counseling may still help families understand inheritance, but pharmacogenetics is not yet a standard part of treatment options for Rombo syndrome.
Interactions with other conditions
People living with Rombo syndrome often deal with skin changes over many years, and the biggest related health concern is a higher chance of developing basal cell skin cancers, especially in adulthood. These cancers usually appear on sun-exposed skin, so a spot that does not heal, slowly grows, or starts to bleed deserves medical attention. Another important aspect is how it may link with other diseases: Rombo syndrome is mainly known for its skin findings, and it is not generally associated with a wide range of internal organ diseases. Even so, early symptoms of skin cancer can be easy to miss because they may blend in with the underlying skin changes already present in Rombo syndrome. For many, this can mean regular follow-up with a dermatologist and careful sun protection to lower added damage to the skin. If someone in the family has similar features or repeated skin cancers, genetic counseling may also help clarify risk for relatives.
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 Rombo syndrome?
Conditions most often confused with Rombo syndrome include Bazex-Dupré-Christol syndrome and Gorlin syndrome, because they can also cause early basal cell skin cancers, small bumps on the face, and changes in hair or skin texture. Some doctors may also consider Brooke-Spiegler syndrome or other rare inherited skin conditions that cause many skin growths, so the pattern of skin changes, family history, and age when symptoms start can help tell them apart.
History
Rombo syndrome entered the medical literature through reports of families with a distinctive mix of skin changes that tended to appear gradually over time. Early doctors did not have the tools available today, so they described what they could see: a thin, dry-looking face, small widened blood vessels on the skin, tiny bumps, and later a higher chance of certain skin cancers. For many living with Rombo syndrome, this history matters because the condition often unfolds slowly, with signs becoming clearer from childhood into adult life rather than all at once.
As medical science evolved, doctors became better at separating Rombo syndrome from other rare conditions that can also affect the skin and hair. That was important, because the early symptoms of Rombo syndrome can look subtle at first and may overlap with features seen in other inherited skin disorders. A child might simply seem to have delicate facial skin or sparse hair, while the fuller pattern only becomes easier to recognize years later.
Over time, case reports from different countries helped build a clearer picture of Rombo syndrome and its long-term course. Researchers later identified that it has a genetic basis, but the condition is still considered very rare, so much of what is known has come from careful follow-up of a small number of affected families. That means knowledge has grown steadily rather than quickly, with each well-documented case helping doctors understand when symptoms usually begin, which features tend to appear together, and why regular skin checks became such an important part of care.
Today, the history of Rombo syndrome is less about a single dramatic discovery and more about gradual recognition. What began as scattered clinical observations has become a more reliable description of a rare skin condition with a characteristic pattern over time. Knowing this background can help people with Rombo syndrome and their families understand why diagnosis may take time, and why doctors often look at both current symptoms and the way the skin has changed over the years.
