Canine transmissible veneral tumor with intra-ocular localization and spleen metastasis

Abstract

The transmissible venereal tumor (TVT), also called Sticker’s Lymphosarcoma, is a round-cells mesenquimatous contagious neoplasia, mainly located in the mucous membrane of both sex dog’s external genitalia. The TVT may exist as a solitary mass or multiple injuries, in cauliflower format, or as pendular forms, nodular, papillary or multilobar ones. This work reports the case of a canine animal species, without defined race, male, 4 years old, 13 kilos, taken care of in the Veterinarian Hospital of the Universidade Federal Rural do Semi-Árido (UFERSA), where TVT, located in the prepuces, was evidenced during clinical examination, beyond total blindness in result of an intra-ocular colored mass that projected itself for out of the right and left ocular globe. Then the animal was directed to the Animal Pathology Laboratory of the UFERSA for accomplishment of the anatomopathological examination. Through the microscopical characteristics, TVT conclusion was allowed. It was a primary injury in the prepuces, with intra-ocular injuries and spleen metastasis.
