A 2-year-old intact female mixed-breed dog with a 1-month history of lethargy and anorexia was evaluated for abdominal distension and an abdominal mass. The dog's last heat cycle, her third, was 1 month prior to presentation, and no reproductive cycle abnormalities were noted at any time. Hematologic and serum biochemical abnormalities were consistent with hemorrhage and inflammation. Ultrasonographic examination confirmed a large midabdominal mass and a moderate amount of abdominal fluid. Cytologically, the fluid showed evidence of pyogranulomatous inflammation, hemorrhage, and mesothelial reactivity, as well as ciliated columnar cells and free cilia that were interpreted as likely of oviductal origin. The mass was removed surgically, and the histopathologic interpretation was oviductal hamartoma with marked stroma formation and acute hemorrhage. To the authors' knowledge, this is the first reported case of oviductal hamartoma in any species and the first reported case detailing the finding of ciliated columnar epithelial cells in the abdominal fluid of a dog. Ciliated columnar epithelial cells in abdominal fluid should be considered indicative of a likely underlying oviductal lesion. (Fry MM, DeCock HEV, Greeley MA, Vernau W.
