Typical Signalment

  • This is a common odontogenic tumour in cats.
  • More rarely found in dogs.

Description

Diagnosis

Clinical Signs

  • halitosis
  • oral bleeding
  • dental disruption or loss
  • facial or mandibular deformity
  • excessive salivation
  • growth protruding from the mouth
  • dysphagia occurs rarely

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 dignostic possibility, thoracic radiography should be carried out to evaluate for lung metastases.

Biopsy

Required for a definitive diagnosis

  • Incisional Biopsy - best
  • Cytological or grab procedures - difficult to obtain a representative sample

Treatment

Prognosis

Good following complete surgical excision.
