Disseminated histoplasmosis diagnosed by fine needle aspiration biopsy of the adrenal gland. A case report

A case of disseminated histoplasmosis diagnosed by fine needle aspiration (FNA) biopsy of the adrenal gland is reported for a 60-year-old man who presented with a 40-pound weight loss and abdominal computed tomography showing bilateral adrenal enlargement. FNA biopsy of the adrenal gland revealed clusters of macrophages with abundant cytoplasm containing the yeast forms of Histoplasma capsulatum. This case emphasizes that FNA is effective in diagnosing infectious as well as neoplastic conditions of the adrenal glands.
