Raymond T. Kuwahara, MD

A 41-year-old man presented with a 3-month history of itchy, scaly feet and right hand. The left hand was unaffected.

Concerned about the yellow plaque on his upper eyelid, a 45-year-old man sought medical evaluation. The slow-growing, asymptomatic lesion had developed several months earlier.

Low-potency corticosteroids had not resolved a rash of several month's duration on the buttocks of a 2-year-old girl.

A 28-year-old man presented to the emergency department with a 1-week history of multiple, concentric, erythemic, targetlike plaques over the entire body. Severe necrosis and hemorrhagic crusting were evident on the oral mucosa and lesions were present on the upper lip. The remainder of the physical examination was unremarkable. The patient had no known medical problems, was seronegative for HIV, and denied a history of herpes simplex virus (HSV) infection. He used no medications.
