Estudo retrospectivo de neoplasmas do sistema digestório em caninos

Abstract

This dissertation is a retrospective study of digestive canine neoplasms, over a 10-year period. We present a paper containing a review of the literature, with the main neoplasms affecting the lower digestive tract lesions and characteristics referring to the most frequent lesions, as well as epidemiological information regarding sex, breed and age. According to the literature, melanocytic lesions are the most frequent in the oral cavity, followed by Squamous Cell Carcinoma. According to the literature, rectal neoplasms are classified separately from other intestinal lesions, because they have different behavior and characteristics from the other intestinal lesions. The third article presents a retrospective study of 108intestinal neoplasms of 98 animals. This article evidences that the lesions of the oral cavity were the most frequent ones, especially Melanomas, Peripheral Odontogenic Fibroma and Fibrosarcoma. In the presence of gastroesophageal lesions, lesions from the smooth muscle predominated. In the intestinal lesions, the most frequent lesions were undifferentiated sarcoma. Neoplasms of the digestive tract are one of the main causes of death of senile animals and their casuistry has been increasing in veterinary medical practice. The literature lacks data on these lesions.
