Description
Summary:Sarcoidosis, a multisystem disease of obscure etiology, is characterized by the formation of noncaseating epithelioid cell granulomas in several organs or tissues. The diagnosis of sarcoidosis requires a compatible clinical picture, histologic demonstration of noncaseating granulomas, and exclusion of other diseases capable of producing similar histology or clinical features. The lung is the most commonly affected organ, but the skin is frequently involved. Sarcoidosis occurs worldwide and affects all ages and races with female predominance. Scalp involvement is decidedly rare among the myriad cutaneous manifestations of sarcoidosis. Alopecia is common in sarcoidosis and is generally scarring in nature. Annular sarcoidosis is a rare morphology and annular sarcoid of scalp is seldom reported. Herein we present a case of annular scalp sarcoid with systemic involvement and without alopecia.
