A large oral lipoma in a young patient: A rare combination.

Lipoma is a benign neoplasm of mature fat cells. Although a common mesenchymal neoplasm of trunk and extremities, its occurrence in the oral and oropharyngeal region is rather rare. Lipoma accounts for 1-5% of all benign oral tumors, occurring in patients above 40 years of age with slight male predilection. Oral lipoma presents as asymptomatic, slowly growing mass rarely exceeding 25 mm in diameter. Documented here is a rare case of a large size lipoma (>3 cm in diameter) occurring as an extraoral swelling in a girl aged 13 years, which was subsequently diagnosed and treated 4 years later. Furthermore discussed are the peculiarities in the clinical presentation, differential diagnosis, and investigations for this case.
