Cistoadenocarcinoma de ovário em cadela: relato de caso

Abstract

Tumors of epithelial origin account for about 40 - 50% of ovarian tumors in dogs, and cystoadenocarcinoma is included in this classification. This neoplasm occurs most often in bitches between 4 and 15 years old and is characterized by a cystic multinodular enlargement of the ovary with glandular growth. Ovarian carcinogenesis is still poorly known. Early diagnosis through abdominal ultrasonography and histopathological evaluations favors an effective surgical treatment, which consists of ovariosalpingohisterectomy, which may ensure longer survival to the animal. The prognosis for this condition depends on the staging of the tumor, as it has great metastatic potential. The aim of the present study is to review the literature on ovarian cystaenocarcinoma and to report a case of ovarian cystoadenocarcinoma in an adult female dog, which was accidentally discovered in the laparotomy to perform ovariosalpingohysterectomy at the same time as a unilateral mastectomy.
