✦ Synopsis

We report on the results of fine-needle aspiration cytology of a case of oncocytic adrenocortical carcinoma in a 39-yr-old man. The tumor invaded the inferior vena cava and extended up to the right atrium. Aspirate smears were very cellular and showed a monomorphic population of large polyhedral cells with abundant granular cytoplasm, predominantly distributed singly. Mitotic activity was inconspicuous, and there was no necrosis. Immunohistochemically, the tumor cells were positive for vimentin, cytokeratin, and p53, and negative for synaptophysin, chromogranin, inhibin, and S-100. Ultrastructurally, the cytoplasm of the tumor cells was packed with mitochondria. The patient underwent left radical nephrectomy as well as a combined cardiopulmonary bypass, with atriotomy and resection of the tumor from the right atrium and inferior vena cava. Three months of postoperative follow-up were uneventful.
