Abstract

A 10-yr-old male South American sea lion (Otaria byronia) died after several weeks of depression, anorexia, weight loss, and progressive respiratory distress. At necropsy, three confluent, lobulated, dark-red masses were noted in the mesentery. Similar masses were also observed in the lung and both kidneys. Hemangiosarcoma was diagnosed based on gross findings, histopathology, and immunohistochemistry. This is the first case of hemangiosarcoma reported in pinnipeds.
