Oral Cavity Tumours - Benign

Papilloma

Papilloma evolves from epithelial tissue and has a prevalence of 0.1 per cent in Sweden [3]. In a clinical situation, papilloma cannot be distinguished from verruca vulgaris. Papillomas are usually stalked and have a cauliflower-like surface, but they can also have a broad base and a fairly smooth surface. Papillomas grow slowly and almost invariably remain benign. They are caused by local trauma, but cases exist where papilloma virus has been demonstrated [8,9]. *CASE*

Fibroma

Fibroma is mainly composed of connective tissue. This lesion is quite rare, the prevalence in Sweden is less than 0.1 per cent [3]. Clinically it is indistinguishable from irritant hyperplasia. The fibroma is usually manifested as solid, well demarcated, rounded structure covered by ordinary mucosa. Local trauma, which occasionally gives rise to an ulcerated surface, is the most common cause of fibroma. Fibroma is a benign tumour, but can grow aggressively [8,9].

Other Lesions

There are a number of other benign tumours in the oral cavity of which the granular cell tumour or myoblastoma should be mentioned. This is a benign tumour of the tongue that is often covered by hyperplastic epithelium and exhibits so-called pseudoepitheliomatous hyperplasia. *CASE* Furthermore, fibroepithelioma, hemangioma and lipoma can be categorized as benign tumours of the oral cavity [8,9].

Management

Benign tumours should be removed and sent for histopathological examination to secure a definitive diagnosis.
