title: Histoplasmosis: a masquerader of sarcoidosis.
abstract: Although endemic along the Ohio and Mississippi River valleys in the United States, histoplasmosis may occur in many parts of the world. The multisystem involvement, the presence of non-caseating granulomas, and an elevated angiotensin converting enzyme in histoplasmosis cause diagnostic confusion with sarcoidosis. A careful epidemiologic history, serological tests, and tissue cultures are helpful in establishing the correct diagnosis.
