Pathological and Immunohistochemical Diagnosis of an Intestinal Leiomyosarcoma in a Zebra Finch

Cardoso, João Felipe RitoLevy, Marcelo Guilherme Bezerra

An adult male Zebra finch (Taeniopygia guttata) with blood in the feces was examined for an internal mass in the abdominal caudal region near to the cloaca. During the necropsy, a large tumor mass around the large intestine was observed.

The results were consistent with intestinal leiomyosarcoma.(AU)
