Sarcoidosis

A 48-year-old woman with an 8-year history of intermittently pruritic papules on the lower extremities suddenly developed pruritus and generalized spread of the lesions over a 1-month period. The lesions appeared as smooth, flat-topped, violaceous, round papules on all extremities, trunk, and back. A biopsy specimen showed sarcoidosis. Cutaneous sarcoidosis has many morphologic presentations and often mimics other dermatologic diseases. Despite widespread cutaneous involvement, she has no systemic involvement. Treatment options are reviewed.
