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. Acanthomatous ameloblastomas have also been known as acanthomatous epulis, peripheral ameloblastomas, basal cell carcinomas and adamantinomas.
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
Radiography may show a soft tissue opacity in the area of the gingiva with lytic invasion of the underlying alveolar bone
Biopsy
Required for a definitive diagnosis
- Incisional Biopsy - best.
- Cytological or grab procedures - difficult to obtain a representative sample.
Treatment
Prognosis
