Concurrent occurrence of intestinal coccidiosis and oral papillomatosis in a buffalo calf

This paper describes a unique case of concurrent oral papillomatosis and intestinal coccidiosis in a six-month-old buffalo calf with a history of anorexia, dysentry, and presence of multiple exophytic masses within the oral cavity. Microscopically, the tumors in the oral cavity were characterized by papillary projections with a fibrovascular core and characteristic koilocytes. Simultaneously, the intestines exhibited a thickened, corrugated, and hemorrhagic mucosa grossly, with coccidial oocysts in the intestinal scrapings. On histopathology, proliferative enteritis was recorded. The findings suggest that the physiological stress and immunosuppression induced by intestinal coccidiosis likely predisposed the calf to the mucosal manifestation of papillomatosis.
