Nature and rate of neoplasia found in captive wild mammals, birds, and reptiles at necropsy.


The nature and rate of neoplasia found at necropsy of captive wild animals of the Zoological Society of San Diego collection were studied. Neoplasia was present at necropsy in 2.75% of 3,127 mammals, 1.89% of 5,957 birds, and 2.19% of 1,233 reptiles. Neoplasms were not detected during 198 necropsies of amphibians. Gross and histologic examinations were performed on the 92 mammalian, 111 avian, and 28 reptilian neoplasms. The lesions were diagnosed. The findings findings included a high frequency of lymphosarcomas in birds and reptiles, multiple lung adenomas in mammals, multiple endocrine tumors in 2 European mouflons (Ovis musimon), and proliferative lesions of the biliary and pancreatic ductal systems in several species.
