The present report aimed to describe a hyperplastic colitis associated with parasitism by Strongyloides sp. in a two-year-old male cat treated in the emergency room presenting tenesmus and rectal prolapse. An exploratory laparotomy was performed in which it was possible to observe transmural nodules in the cecum and colon, with a diameter varying between 2 and4 mm, with a multifocal to coalescent distribution, firm consistency which, when cut, contained blood. Histologically, the nodules were circular areas composed of projections from the intestinal mucosa to the submucosa, formed by tubular structures covered by a layer of bulky monomorphic enterocytes and rare goblet cells. Rhabditoid larvae, filarioids, and adults with morphologies compatible with nematodes of the genus Strongyloides were observed in the lumen of the hyperplastic epithelium, between the tubules and at the edge of the nodules, possibly constituting the primary cause of these changes in the animal.Downloads
