title: Apocrine gland adenocarcinoma and pheochromocytoma in a cat.
abstract: A 15-year-old, castrated male domestic shorthair was presented for a recurrent, perineal apocrine gland adenocarcinoma. A right adrenal mass was identified on abdominal radiography and ultrasonography performed as routine staging prior to surgical excision of the perineal tumor. An ultrasonographic-guided biopsy of the adrenal mass was performed and a pheochromocytoma was diagnosed upon histopathology. The perineal and adrenal tumors were removed surgically. The cat developed fatal thromboembolic disease following surgery and was euthanized. This is the third reported case of phenochromocytoma in a cat and is unusual in that two rare tumors were identified in one animal.
