Polymorphic Eruption of Extensive Cutaneous Sarcoidosis.

A 40-year-old man presented with a 1-year history of asymptomatic multiple raised reddish lesions that started on the face and gradually progressed in size and number to involve the neck, trunk, and arms. There was no history of fever, fatigue, weight loss, arthralgia, cough, dyspnea, or ocular complaints. Past and family history was insignificant, and no significant drug history could be elicited. On examination, multiple reddish brown, shiny, firm papuloplaques and nodules were present over the face, neck, and arms. There was a reddish brown plaque with central depression and overlying prominent telangiectasia over the left perioral area. The lesions over the posterolateral aspects of the arms were atrophic with peripheral reddish brown papules and central clearing, assuming an annular configuration. There were multiple large indurated subcutaneous and atrophic plaques over the arm and back. The palms, soles, hair, nail, and mucosal areas were not involved.
