Mastocitoma intestinal em felino

Abstract

The mast cell tumor is the third neoplasm that most affects felines, and its intestinal form is uncommon. The present report aims to describe the main ultrasound and radiographic changes found in an elderly feline, mixed breed, with nonspecific clinical signs, such as vomiting, constipation and progressive weight loss. The patient underwent an ultrasound examination at the University Veterinary Hospital of the Federal University of Santa Maria - HVU/UFSM, where focal alteration was evidenced, with thickening of the intestinal segment (jejunum) and loss of layer stratification, compatible with neoplasia and reactive adjacent lymph nodes. After enteroanastomosis surgery, samples of the intestinal loop and affected jejunal lymph nodes were sent for histopathological examination, which confirmed intestinal mastocytoma with metastasis in lymph nodes.
