Sarcoma gástrico em cão: Relato de caso

Abstract

Gastric tumors in domestic animals are rare and the literature is scarce. In humans this tumor represents 80% of mesenchymal tumors of the digestive tract, most commonly in the stomach (70%). Affected individuals are middle-aged and elderly, especially males, diagnosed from its clinical manifestations in association with typical cell morphology and positive immunohistochemistry. The aim of this report was to describe a gastric sarcoma in a dog, as well as the diagnosis, surgical and post surgical treatment. The experiment was conducted in the Veterinary Hospital of the Metropolitan University of Santos (UNIMES) on a male dog, SRD, 10 years old, 8.3kg, castrated, in a good general condition, with complaint of emesis for year. In the abdominal ultrasound exam we observed the presence of a round formation in the stomach which measured 3.20 x 2.61cm, located in the epigastric region contiguous with the wall. The dog was submitted to gastric endoscopy, in which the presence of a rounded mass in the pyloric region was observed, and laparotomy and gastrostomy were performed. The removed tumor was sent for pathologic evaluation, where the findings were compatible with gastric stromal sarcoma.
