Living with Syringocystadenoma papilliferum

A noncancerous skin growth that appears in childhood or the teens, usually as a bump or plaque on the head or neck.

Understanding Syringocystadenoma papilliferum

Syringocystadenoma papilliferum is a benign (noncancerous) skin growth from the skin's sweat glands.

It occurs during childhood or the teen years. It usually shows as a small bump (papule) or a plaque on the head and neck. It may arise in a skin birthmark such as a sebaceous nevus. Removing the whole growth is curative.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Small bump (papule) on the skin
  • Plaque on the head or neck
  • Firm lump under the skin
  • Sparse scalp hair
  • Blistering skin

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include cancer specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in BRAF are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
