Living with Nevus comedonicus syndrome

A rare skin condition with groups of plugged hair follicles, usually on the face and neck, that appears in childhood.

Understanding Nevus comedonicus syndrome

Nevus comedonicus syndrome is a rare skin condition with patches of plugged, widened hair follicles, most often on the face and neck.

The patches look like a honeycomb of plugged pores. They can be on one or both sides of the body, in lines, or in segments. They may look like acne, or form cysts, bumps, pustules, and abscesses. In most people the condition develops in the first ten years of life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Blackhead-like plugs in skin pores (comedones)
  • Benign skin overgrowths (hamartoma)

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 NEK9 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Foundation for Ichthyosis and Related Skin Types may keep lists of experts for this condition.
