An eleven-year-old male Yorkshire terrier weighing 2.6 kg with a primarily indoor lifestyle was presented for cardiopulmonary examination due to a 6-month history of difficulty breathing. No cardiopulmonary abnormalities were detected but the history included bilateral serous nasal discharge and oral abnormalities were evident. Examination under general anaesthesia confirmed advanced periodontal disease with oronasal fistulae detected at the maxillary canine teeth. Dental treatment, including repair of the oronasal fistulas, appeared to resolve the respiratory signs but the discharge reappeared at the left nostril 1 month later. There was no evidence of persistent or recurrent oronasal fistula, so rhinoscopy was performed identifying a mass in the left nasal cavity. Histopathological examination identified the biopsy specimen as a low-grade predominantly papillary-cystic adenocarcinoma combined with transitional carcinoma.
