A Case of Cavitated Uterine Mass from Müllerian duct in a Mixed Breed Dog

This report describes a case of newly recognized congenital $M{\ddot{u}}llerian$ duct anomaly in a bitch. A fourteen-year-old, mixed breed bitch was presented with mild hematuria and mammary gland tumor. Complementary examinations were performed and abdominal ultrasonography revealed distended uterine horns and uterine tumor-like mass around the right ovarian area. Macroscopic examination showed the mass to be on the level of insertion of the right round ligament. The mass was cystic in nature, and had no communication with the uterine cavity. Histopathologically, the mass was identified as an accessory cavity lined by functional endometrium, which confirmed the diagnosis of accessory and cavitated uterine mass.
