Psoriasiform Sarcoidosis

ABSTRACT

Sarcoidosis is a systemic granulomatous disease of undetermined etiology and pathogenesis that involves the skin and many of the internal organs. It involves any organ of the body; how-ever, the most common sites are the lung, lymph node, skin, and eye. Psoriasiform eruption is a rare morphologic manifestation of sarcoidosis. We report herein a case of 36-year-old man with psoriasiform papules on the elbows, forearms and knees of 5-year duration. Histopathologic examination revealed sarcoid granuloma throughout the dermis. This is the second case of psoriasiform sarcoidosis in Korea.
