Description
This is a benign but locally invasive odontogenic tumour that appears in the gingiva, often surrounding and displacing the adjacent teeth. The lesions have a raised and cauliflower appearance and are slow growing. Eventually the lesions can become very large and involve the jaw bone.
Signalment
Common oral tumour in dogs but rarely occurs in cats.
Diagnosis
Clinical Signs
Include halitosis, oral bleeding, dental disruption or loss, facial or mandibular deformity, excessive salivation, growth protruding from the mouth and rarely dysphagia.
Diagnostic Imaging
Skull radiography may show a soft tissue opacity in the area of the gingiva with lytic invasion of the underlying alveolar bone. If a malignant neoplasm is a diagnostic possibility, thoracic radiography should be carried out to evaluate for lung metastases.
Biopsy
Required for a definitive diagnosis and incisional biopsy is the technique of choice. When undertaking cytological or grab procedures it is more difficult to obtain a representative sample.
Treatment
Surgical resection is the best option with margins of at least 1cm. Radiation therapy may be considered in patients where wide surgical excision is not possible, however there is a risk of malignant transformation of the tumour at a later stage.
Prognosis
Good following complete surgical excision.
Literature Search
Use these links to find recent scientific publications via CAB Abstracts (log in required unless accessing from a subscribing organisation).
