Oral fibrosarcoma of low histological grade and high biological aggressiveness: case report
ABSTRACT. The objective of this report was to describe the occurrence of a fibrosarcoma in a 12-year-old golden retriever, weighing 42 kg. The animal presented a clinical history of increased nasal plane volume. At the specific examination of the oral cavity, a mass adhered to the rostral portion of the maxilla was found, encapsulated, measuring about 5 cm in diameter, which extended cranially to the nasal plane, causing its obstruction. An incisional biopsy was performed and the diagnosis was made based on the histopathological evaluation. The animal was submitted to neoadjuvant chemo-radiotherapy and bilateral rostral maxilectomy. To date no locoregional recurrence or metastatic disease has been observed. In Brazil, reports of literature involving radical or reconstructive surgeries in oronasal tumors are still scarce.
