Oncocytoma presenting as a choanal polyp: a case report.
Oncocytomas account for less than 1% of all salivary gland neoplasms. Histochemical methods and electron microscopy showing the large amount of characteristic mitochondria have made the definition of the tumor more precise. A solid oncocytoma originating in the nose and presenting as a choanal polyp is described. Pre- and postoperative CT scans are shown as light and electron microscopy photomicrographs. The tumor had no invasive or other malignant characteristics and was therefore classified as a benign oncocytoma.
