Painful Erythematous Plaques on the Trunk

Abstract

A woman in her 40s presented with painful erythematous plaques on her trunk (Figure , A). Skin lesions developed 2 months earlier and progressively spread. She reported abdominal discomfort, weight loss, and vaginal bleeding. A solid mass on her lower abdomen that had been palpable about 10 years prior had rapidly increased in size within the past few months. Physical examination revealed erythematous plaques on the right chest and flank without warmth. Punch biopsy of a lesion from the chest was sent for histopathological examination (Figure, B and C).
