Nosectomia em felino portador de carcinoma de células escamosas: relato de caso

Abstract

Squamous cell carcinoma (SCC) is a malignant neoplasm commonly seen in older, fair-skinned cats chronically exposed to ultraviolet (UV) radiation. Considered one of the most common neoplasms in Veterinary Medicine, representing about 15% of skin tumors that affect domestic cats. The most common locations in cats are the nasal plane, ears and eyelids. The aim of this study was to report a case of nosectomy in a 14-year-old feline with squamous cell carcinoma, with a history of treatment with Itraconazole during a 2-year period with no response, with progressive evolution of the lesion in the nasal plane. We opted to perform the anesthesic protocol with acepromazine and methadone, intramuscularly, for the pre-anesthetic step, during anesthetic induction, propofol was administered, intravenously and for maintenance of general anesthesia, isoflurane was used. Then, the nosectomy procedure was performed, using the basic technique of resection of the nasal plane with skin incision and excision of neoplastic mass in the nasal cavity with the association of a reconstruction technique, aiming at facial aesthetics. The patient recovered and gained weight but presented a relapse that required a new intervention. It is concluded that the technique, besides making the diagnosis possible, provided the animal with quality of life.
