REPORT OF A CASE
A 64-year-old man presented with a two-year history of a slowly enlarging nontender pruritic mass on his left thigh. Two years prior to evaluation he had noticed two small scaling psoriasiform patches on his inner left thigh, each approximately one half inch in diameter. Treatment with topical steroid therapy for psoriasis had no effect on these lesions, whereas other psoriatic lesions on the left middle aspect of his abdomen resolved with therapy. No biopsy specimen was taken from these lesions. Over the following year the two left thigh patches expanded and coalesced, forming an elevated ringlike tumor. This tumor quadrupled in size during the next year. The patient denied any pain or weight loss. He noted a small psoriasiform lesion on his left calf at the time of admission.Physical examination revealed an annular, fungating, violaceous, weeping tumor with several ulcerations, approximately 16 × 25 cm on the left medial and posterior aspects
