Abstract

: A series of eight cases of intestinal adenocarcinoma in Amazon milk frog (Trachycephalus resinifictrix) is described. All cases presented with signs of inappetence and weight loss, and evidence of large intestinal distention on gross postmortem, with six of the eight cases showing a grossly visible large intestinal mass. Histologic examination identified the mass as an intestinal adenocarcinoma in all cases. No specific etiologic agent could be identified. This is the first report of neoplasia in the Amazon milk frog, and the first reported series of amphibian gastrointestinal neoplasia.
