Abstract
Adrenal histoplasmosis is an uncommon mycotic disease typically caused by Histoplasma capsulatum. The objective was to determine the clinicopathological findings in adrenal histoplasmosis. Pathological records were searched from the database at the Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University from 1993 to 2008 for cases of adrenal histoplasmosis. The keywords were "histoplasmosis" and "adrenal gland". Adrenal histoplasmosis was diagnosed by histopathology and Gomori-Grocott methenamine silver staining. Histoplasma capsulatum was confirmed by tissue culture and/or serology. The authors report seven cases of adrenal histoplasmosis in immunocompetent patients. The mean age at diagnosis was 67 years. All patients presented as chronic fatigue syndrome. The onset of symptoms ranged from one to three months. Addison's disease was found in adrenal histoplasmosis in one case (14.3%). The computed tomography revealed adrenal nodules measuring 1.2 to 7.8 cm in diameter. The histopathology showed granulomatous inflammation with caseous necrosis. Culture of adrenal tissue from two patients revealed Histoplasma capsulatum. Serum Histoplasma antibodies were positive in four cases. A cure was accomplished in 6 out of 7 cases (85.7%). The patients were followed up for 2.5 to 16.5 years.
