This 6 year old pointer mix dog is missing a canine tooth.
The referring veterinary hospital in Atlanta took radiographs and found an unerupted canine tooth.
Surgical removal of the tooth and what appeared to be cyst-like material was completed and the tissue sent for histopathology. The most likely diagnosis is dentigerous cyst.
Communication with the nasal cavity was evident. All abnormal tissue was removed.
The defect was closed and the patient did very well postoperatively. An unfavorable diagnosis of osteosarcoma was made on histopathology. Although the prognosis is better in general for oral osteosarcoma the tissue was very diffusely distributed. Chemotherapy is a followup option.
