Tratamento de fibrossarcoma grau II em um felino submetido a hemipelvectomia parcial medial a caudal

Abstract

Fibrosarcoma is a soft tissue sarcoma originated from mesenchymal cells called fibroblasts, which can occur in canines and felines. Arrived for care at the University Veterinary Hospital (HVU/UFSM), A male, mixed-breed feline was attended by the surgery department, with a main complaint of increased volume in the left pelvic region associated with lameness. At screening, hematological and biochemical tests and aspiration cytology were requested. Due to the cytological suggestiveness of sarcoma, it was decided to perform chest radiography, in the search for metastases and of the affected limb, to assess the degree of tumor infiltration. Due to the wide invasiveness, the animal was referred for mass excision through medial to caudal partial hemipelvectomy associated with limb amputation. The histopathological report revealed that it was a grade II fibrosarcoma with compromised margins. After four months there was local recurrence and adjuvant therapy with electrochemotherapy was established, but without response, culminating in the death of the feline. It is then concluded that the medial to caudal partial hemipelvectomy procedure was beneficial to improve the animal's survival and quality of life, but it was not sufficient in isolation to cure the animal of the neoplasm.
