[Subcorneal pustular dermatosis: report of one case].

We report a 35-year-old female patient with a one year history of a pustular and painful erythematous dermatitis, located in great folds, pubis and abdomen. She was evaluated in primary health care, receiving antifungal treatment, antimicrobials, topical and systemic non-steroidal anti-inflammatory drugs, with no response. A skin biopsy was compatible with subcorneal pustular dermatosis.
