Peritoneal mesothelioma in a jaguar (Panthera onca).
A 21-yr-old female jaguar (Panthera onca) died in a zoo in Teresina, Piaui, Brazil, following a history of abdominal distension, ascites, anorexia, and dyspnea. At necropsy, a dark red, watery, blood-tinged serous fluid was present in the abdominal cavity. The peritoneum was thick with firm, yellow, villous projections. Histologically, the tumors were composed of a biphasic population of cells, which reacted to anti-cytokeratin and anti-vimentin antibodies, consistent with a biphasic benign mesothelioma of peritoneal origin. This is the first reported case of mesothelioma in a captive jaguar.
