Teratoma ovarico di tipo immaturo in due manze

A 15 months-old Simmental heifer (SH) and a 18 months-old Marchigiana heifer (MH) were referred to the Faculty of Veterinary Medicine of Teramo (Italy). In the first heifer, clinical examination of the vulva, vestibulum, and vagina showed no signs of disease and no discharge was detected. Palpation per rectum revealed a mass in the left portion of the abdominal cavity, closely attached to the tip of the left uterine horn. The mass was mainly firm and fibrous and its surface was slightly lobulated. The second heifer had a history of a regular cycle from the 11thto the 14thmonth of age followed by an anoestrus state. Gynecological examination revealed the presence of a large and firm mass in the caudal left region of the abdomen, soon over the edge of the pelvis floor. In both cases, the histologica examination of the mass revealed an immature ovarian teratoma.
