title: Histoplasmosis presenting with joint pain and hilar adenopathy. "Pseudosarcoidosis".
abstract: During 2 recent epidemics of histoplasmosis in Indianapolis, 7 patients with hilar adenopathy and joint complaints were identified who were initially considered to have sarcoidosis, but in whom histoplasmosis was ultimately diagnosed on the basis of a positive culture for Histoplasma capsulatum or serologic studies. Articular features were the sole presenting complaints in 3 of these patients. All had arthralgias, which were generalized or confined to the lower extremities and were additive rather than migratory. Only 1 patient had joint swelling. Two had erythema nodosum. In all but 1 patient, the articular symptoms resolved rapidly and completely with minimal therapy. The data emphasize that sarcoidosis is a diagnosis of exclusion and that granulomatous infectious diseases must be excluded in patients with hilar adenopathy and joint disease.
