ABSTRACT
Lipomas of the oral cavity are not uncommon, but its location in the floor of the mouth is a rare entity. They are soft tissue mesenchymal neoplasm’s of mature adipose tissues. Its overall incidence of occurrence in the oral cavity is 1-5% of all benign oral lesions. Oral lipomas can occur at various anatomic sites, including buccal mucosa, tongue, major salivary glands, and floor of the mouth. Although benign in nature their progressive growth may cause interference with speech and mastication due to the tumors’ dimension. In this article, the author reports an unusually large lipoma occurring in the floor of the mouth in a 44-year-old female patient. The present case is worth presentation considering the relative rarity with respect to the location and the size of the lesion.
