Intraoral lipoma. A rare cause of dysphagia.

Lipomas of the oral cavity are rare and in most cases asymptomatic. A case of lipoma in the floor of the mouth in a 89-year-old man, causing severe dysphagia and difficulty with speech, is presented. After surgical excision of the lipoma, the symptoms disappeared. Histologically, lipomas are composed of mature fat cells. Their aetiology is uncertain. Recurrence after surgical excision is unusual.
