REPORT OF A CASE
A 60-year-old man was referred to the Outpatient Dermatology Clinic of the American University of Beirut (Lebanon) Medical Center complaining of a 6-month history of asymptomatic skin lesions on the trunk. These lesions had started as hyperpigmented brownish scaly macules and gradually progressed into plaques. Burning sensation over the hands and feet accompanied the skin lesions. There was no history of sensory deficits. The patient's other medical history and family history were noncontributive. Results of routine laboratory investigations, including complete blood cell count, erythrocyte sedimentation rate, and levels of fasting serum glucose, alkaline phosphatase, and serum glutamic oxaloacetic transaminase, were all within normal limits.Physical examination revealed multiple discrete and confluent plaques ranging from 1 to 7 cm in size. The plaques were symmetrically distributed over the trunk, and to a lesser extent over the proximal upper and lower extremities (Figs 1 and 2). A
