Disease Profile

CYLD cutaneous syndrome

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Age of onset





Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

CYLD cutaneous syndrome causes the growth of several types of non-cancerous (benign) skin tumors. Tumors mainly grow on the scalp and face, but can also grow on the torso, genitals and armpits. Tumors usually first appear in the teens or early adulthood. The types of tumors that occur in CYLD cutaneous syndrome may include cylindromas, spiradenomas, and trichoepitheliomas. The number of tumors increases over time, and in severe cases, tumors can cover most of the scalp. Rarely, a tumor will become cancerous. Other complications may include an increased risk to develop basal cell cancer of the salivary gland or deafness due to the growth of a tumor in the ear canal. CYLD cutaneous syndrome is caused by genetic variants in the CYLD gene and is inherited in an autosomal dominant pattern. Diagnosis of CYLD cutaneous syndrome is based on the symptoms, clinical exam, and microscopic exam of the tumor tissue. Results of genetic testing may help confirm the diagnosis. Treatment is focused on managing the symptoms, and typically involves many surgeries to remove the tumors.[1][2][3][4]

The conditions known as Brooke-Spiegler syndrome, familial cylindromatosis, and multiple familial trichoepithelioma are now recognized to be part of CYLD cutaneous syndrome.


The following list includes the most common signs and symptoms in people with CYLD cutaneous syndrome. These features may be different from person to person. Some people may have more symptoms than others and symptoms can range from mild to severe. This list does not include every symptom or feature that has been described in this condition.

Symptoms of CYLD cutaneous syndrome may include:[1][2]

  • Multiple non-cancerous skin tumors
    • Cylindromas (smooth, pale pink growths)
    • Spiradenomas (painful sweat gland tumor)
    • Trichoepitheliomas (small skin-colored growths)
  • Salivary gland cancer
  • Hearing loss due to tumors in the ear canal

Tumors usually first appear in adolescence, but may appear later in life. The face and scalp are most often affected, but tumors can also grow on the torso, armpits, groin, and genitals. In severe cases, tumors may cover the entire scalp. The number of tumors increases with age. People with CYLD cutaneous syndrome are at increased risk for cancer. In addition, they may have psychological and social issues due to multiple facial and scalp tumors.[2][3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

CYLD cutaneous syndrome is caused by the CYLD gene not working correctly. DNA changes known as pathogenic variants are responsible for making genes work incorrectly or sometimes, not at all.[1]


CYLD cutaneous syndrome is diagnosed based on the types of tumors, a clinical exam, and may be confirmed by the results of genetic testing. Additional testing may include a microscopic examination of a piece of tumor tissue (biopsy). The types of tumors found in CYLD cutaneous syndrome include cylindromas, spiradenomas, and trichoepitheliomas.[1][2][3]

Testing Resources

  • The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.


Treatment for CYLD cutaneous syndrome is focused on managing the symptoms. Multiple surgeries may be needed to remove the tumors.[1][2] 

Specialists involved in the care of someone with CYLD cutaneous syndrome may include:

  • Dermatologist
  • Plastic surgeon
  • Oncologist
  • Psychologist/Psychiatrist
