title: Tubulopapillary mammary carcinoma in a brown bear (Ursus arctos).
abstract: A 28-yr-old, nulliparous female brown bear (Ursus arctos) at the Karacabey Ovakurusu Bear Sanctuary presented with an enlargement of the mammary gland. Three other nodules were also noted in the proximity of the mammary gland and over the vulva. Clinical, hematologic, ultrasonographic, and radiologic examinations were performed; the enlarged mammary gland was removed and the other masses were also excised. Histopathologic examination revealed tubulopapillary carcinoma of the mammary gland, and the other masses were diagnosed as epidermoid cysts. This is the first reported case of tubulopapillary mammary carcinoma accompanied by epidermoid cysts in a bear.
