Noninfectious granulomas: Sarcoidosis

Abstract

Sarcoidosis is a noninfectious granulomatous disease of unknown etiology, in which genetic, immunological, environmental and infectious factors seem to participate in the pathogenesis. Any organ or system can be affected with a wide range of clinical manifestations. As involvement of the skin occurs in approximately 20 to 35% of the cases, the dermatologist may play an important role in the diagnosis of the disease. Epidemiology, immunology and treatment are also discussed to provide a better understanding of this entity. ©2007 by Anais Brasileiros de Dermatologia.
