A 40-year-old woman presented with a 3-year history of an erythematous rash in the axillary and groin regions. Originally, the lesions were small, tense papules; gradually, they evolved into crusted plaques. Six months before the patient’s physical examination, similar lesions had appeared on the anterior aspect of her neck. The involved areas were quite tender and often stung. Her medical history included Wilson disease, which was treated with penicillamine, and endometriosis, which was well controlled with medroxyprogesterone acetate.
