Articular histoplasmosis

Rheumatic manifestations of histoplasmosis are uncommon. Polyarthritis or arthralgias may occur as a part of a sensitization process in primary acute histoplasmosis. Infectious arthritis may accompany disseminated histoplasmosis or occur as solitary monoarthritis. Treatment of the latter traditionally consists of surgical excision followed by amphotericin B. Reports of clinical experience with the newer triazole compounds in treating articular histoplasmosis are lacking. We describe a patient with solitary monoarticular histoplasmosis of the knee who was successfully treated with oral fluconazole and required no surgical intervention. Specific issues that pertain to clinical presentation and management of articular histoplasmosis are discussed.
