Abstract
A 37 year old white man presented in August 1997 with a history of pain in the left wrist, right ankle, and both feet during the previous three months. His past history and physical examination were unremarkable except for synovitis in the painful joints and a single well demarcated erythematous hyperkeratotic plaque on the trunk. A dermatologist was consulted and psoriasis vulgaris was confirmed by biopsy.
