Living with Erosive pustular dermatosis of the scalp

A rare long-lasting scalp inflammation with painful pimples and crusts that can lead to scarring hair loss.

Understanding Erosive pustular dermatosis of the scalp

Erosive pustular dermatosis of the scalp is a rare, long-lasting inflammation of the scalp.

It usually occurs in older women (over 70). It causes painful pustules (pus-filled bumps), shallow open areas, and crusting on thin skin. Over time, this can lead to scarring hair loss (cicatricial alopecia).

Signs & symptoms

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

  • Painful pustules (pus-filled bumps)
  • Shallow open areas on the scalp
  • Redness
  • Crusting
  • Scarring hair loss on the scalp

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 skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
