Common oral tumour in dogs but rarely occurs in cats
Common oral tumour in dogs but rarely occurs in cats.
==Diagnosis==
==Diagnosis==
===Clinical Signs===
===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===
===Diagnostic Imaging===
Skull radiography may show a soft tissue opacity in the area of the [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|gingiva]] with lytic invasion of the underlying [[Alveolar bone - Anatomy & Physiology|alveolar bone]]. If a malignant neoplasm is a dignostic possibility, thoracic radiography should be carried out to evaluate for lung metastases.

Required for a definitive diagnosis
Incisional Biopsy is the technique of choice. When undertaking cytological or grab procedures it is more difficult to obtain a representative sample.
==Treatment==
==Treatment==
Surgical resection 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.
