Infectious Diseases and Mycology

The occurrences of neoplasia’s in the nasal cavity in dogs occur in approximately 1% of all neoplasms. Olfactory neuroblastoma is a neuroepithelial neoplasm of the nasal cavity and paranasal sinuses rarely reported in dogs and has as main clinical signs epistaxis, sneezing, respiratory distress, facial deformity and neurological changes. For definitive diagnosis, histopathological examination is indispensable, and extensive mitosis, pleomorphism and necrosis are generally observed. There is still no standard protocol for the treatment of olfactory neuroblastoma, but removal of the tumor followed by radiotherapy is the treatment modality that has given the patients a longer survival time. The objective of this work was to report a case of olfactory neuroblastoma in a dog with no defined breed at eleven years old, highlighting the diagnostic methods for this disease, with emphasis on tomographic and histopathological findings.
