Abstract: Osteosarcoma is the most common bone tumor in dogs. The usual sites are the axial and the appendicular skeleton. However, the involvement of the paranasal sinuses and the nasal cavity is considered extremely rare. The present study describes a six-year-old, female, mongrel dog with a mass located in the right nasal cavity and 90-days of evolution. Radiographic, rhinoscopy and computed tomography findings suggested the presence of an intranasal tumor. The histopathological examination associated with clinical and imaging findings allowed to define the presence of osteosarcoma in the nasal cavity. The patient had an overall survival time of 12 months after diagnosis. Keywords: Bone tumor, dog, neoplasia, veterinary pathology.

Abstract: Osteosarcoma is the most commonly reported bone tumor in dogs, typically affecting the axial and appendicular skeleton. Involvement of the paranasal sinuses and the nasal cavity is extremely rare. This report describes a six-year-old, female, cross-breed dog presented with signs of 90 days duration and diagnosed with a mass located in the right nasal cavity. Radiography, rhinoscopy and computed tomography findings suggested the presence of an intranasal tumor. Osteosarcoma in the nasal cavity was diagnosed based on histopathological examination and clinical and imaging findings. Survival time was 12 months from diagnosis.
