A 26-year-old man who worked in the science fiction department of a bookstore presented with a 3-month history of intermittent gray-green skin discoloration. The discoloration was first noted around his left wrist and subsequently spread to involve the upper part of his arms and his chest, neck, and groin. His face was never affected. The discoloration appeared and disappeared over time, lasting anywhere from several minutes to hours. The patient was otherwise asymptomatic, although he had begun bathing twice daily to try to get rid of the discoloration. His medical history included psoriasis, which had been treated by his family physician with a refined alcoholic extract of coal tar with allantoin (Alphosyl) and a tar shampoo. He had also suffered from depression, which had previously been treated with dothiepin hydrochloride (Prothiaden) and lofepramine hydrochloride. At the time of presentation, he was taking no medication.
