Adenocarcinoma endometrial em uma coelha (Oryctolagus cuniculus) / Endometrial adenocarcinoma in a rabbit (Oryctolagus cuniculus)

RESUMO

Background: Uterine tumors are classified according to their origin, epithelial or mesenchymal. These neoplasms are uncommon in most animal species, but are considered as important causes of reproductive disorders. In rabbits, the occurrence of these tumors increase with development of the animals and, although the numbers indicate a high occurrence of this disease in rabbits, reports are scarce. Therefore, this paper has the objective to describe a case of endometrial adenocarcinoma in a rabbit, emphasizing their histological features as well as provide a brief discussion about the epidemiological, clinical, pathological and prevention forms and treatment. Case A 4-years old New Zealand rabbit breed, from a group of animals maintained only for breeding, had low fertility. The rabbit was twice covered by proven fertile animals, but no pregnancy, becoming unfit reproduction and subjected to euthanasia. At necropsy, tissue samples were collected, subsequently fixed in 10% formalin and then were processed routinely and stained with hematoxylin and eosin for histopathological analysis. Grossly, there was swelling of the uterine body, characterized by two masses that protruded from the endometrium, with rounded and soft look, and the court had cystic cavity filled with whitish gelatinous consistency of content. Microscopic cancer cells that originated from the endometrial...(AU)
