다국어 초록 (Multilingual Abstract)

Erosive pustular dermatosis of the scalp (EPDS) is a rare inflammatory disorder of the elderly, characterized by sterile pustules and chronic erosions on the scalp, leading to cicatricial alopecia. Variety types of trauma have been reported as the predisposing factors of EPDS. A 38-year-old woman presented with a 6-year history of progressive erythematous patch with erosions and crusted pustular lesions on her scalp. The lesion initially had begun at the frontal area mimicking seborrheic dermatitis, and developed to the entire scalp. Several treatment methods including systemic and topical steroids, antibiotics and herbal medicine have been tried, but recurrence have continued. She had no history of any other medical problems or trauma history. Skin biopsy revealed mixed dermal infiltrate of lymphocytes and neutrophils. KOH test, bacterial and fungal cultures showed negative results. Systemic steroids and cyclosporine were tried and, after 2 months, the erosive and pustular lesions almost resolved. No recurrence has been observed during 6-month with topical tacrolimus. There is no single diagnostic finding or test that confirms EPDS, so the exclusion of other conditions should be needed to make a diagnosis. Herein, we present a rare case of EPDS occurred in a young woman without any trauma history. Clinicians need keep EPDS in mind when confronting relapsing inflammatory dermatosis of the scalp to prevent permanent cicatricial alopecia.
