The incidence of cancers in domestic dogs has increased greatly in recent years, drawing interest from areas such as oncology, clinical and veterinary pathology. Among these tumors, it has been highlighted the ovarian neoplasms such as ovarian teratoma, rare in domestic animals and it is characterized by the composition of multiple tissues foreign to the ovary, such as skin and appendages, bone, fat, nerve, occurring more frequently in young animals. This study aimed to report a case of ovarian teratoma in a German Shepard dog, two years old, which received treatment in the Veterinary Hospital at the Federal Rural University of Amazonia. The animal was euthanized and the complete necropsy examination was performed. The thoracic cavity was inspected and it was evident the presence of serosanguineous fluid aspect. In the abdominal cavity, it was observed a large intra abdominal mass rounded in shape and irregular surface, lobulated, firm consistency with cystic aspect structuresOn histopathological examination of the abdominal mass, it was observed several types of tissues such as adipose tissue, cartilaginous plates and presence of cysts containing keratin material. The results corroborate those reported in the literature studied.
