Item Mandibulectomia parcial para exérese de neurofibrossarcoma em cão - Relato de caso(2021-12-06) Gouveia, Igor Soares; Cavalcanti, Grazielle Anahy de Sousa Aleixo; http://lattes.cnpq.br/3165940085830406; http://lattes.cnpq.br/8150604312901033The Mandatory Supervised Internship (referred as ESO in Portuguese) is referent to the last term of the Veterinary Medicine degree at the Federal Rural University of Pernambuco, where the student will have 420 hours of extracurricular activities and will develop a final paper. The ESO was carried out in two different clinics. The first in the Animalis surgery sector – Surgery and Veterinary Clinic, and the second in the Oncology Surgery sector of CORe – Veterinary Oncology, both located in Recife municipality, Pernambuco state, Brazil. Several species of domestic and wild vertebrates were treated during the internship experience, adding up to 58 patients. During the internship at CORe, we recorded and avaluated a study case of oral neurofibrosarcoma in a dog. Neurofibrosarcoma or malignant tumor of the peripheral nerve sheath is a highly infiltrative neoplasm that commonly affects the brachial and lumbosacral plexus, nerve roots and, sometimes, the cranial nerves which is rarely described in Veterinary Medicine. The treatment indicated for malignant oral neoplasms is the surgical excision, which may be just a palliative procedure. This study aimed to report the case of an 11.7 years-old German Shepherd dog, weighing 35 kg, that had a multilobed nodule growing in the left mandible. This nodule showed a shatterable aspect, histopathological grade II soft tissue sarcoma and immunohistochemical profile that suggested neurofibrosarcoma - malignant tumor of the peripheral nerve sheath. Was performed a partial mandibulectomy procedure with preservation of the temporomandibular joint as the healing method for this type of neoplasia, along with a left mandibular lymphadenectomy. The histopathological examination conducted after surgical removal concluded that the nodule was a non-metastatic lymph node with free physical margins. Post-surgical complications were lateral lingual projection and difficulty in feeding itself. After the recovering interval the patient should be referred to chemotherapy.
