Case Reports of Three Patients with Lipomas in the Oral Cavity

Abstract

Benign soft tissue neoplasms commonly occur in the oral cavity. Lipoma is one of the benign mesenchymal tumors which rarely occurs in the oral mucosa. About 20% of lipomas are seen in the head and neck region among which oral lipomas take place only 1-4% of all lipomas. They occur as slow growing, painless, asymptomatic submucosal masses which can cause speech, mastication and denture problems if only they extend to large sizes. Surgical excision is the proper choice of treatment. In the histopathological evaluation, most oral lipomas are composed of circumscribed mass of mature fat cells with varying number of collagen fibers mixing through the lesion and supporting small blood vessels. Here we present three cases with oral lipomas to emphasize this rare entity.
