Pheochromocytoma in an accessory adrenal gland: a case report.

Very few cases of pheochromocytoma in functional accessory adrenal glands have been documented in literature. We present a twenty-four year old Nigerian female who presented with pheochromocytoma. Investigations revealed a suprarenal mass, which was diagnosed as an accessory gland adrenal tumour at surgery. This shows that accessory adrenal glands can be a basis for development of pheochromocytoma.
