[Intraoral lipoma in the region of the mental nerve--report of a case and review of the literature].

The intraoral lipoma is a benign, slowly growing, painless soft tissue neoplasia, which can cause esthetic or functional problems for the patient, depending on its size. All parts of the body can be affected, whereas the oral cavity is rarely involved. Clinically, the tumour often exhibits an exophytic growth pattern, a soft consistency, a broad base connected to the underlying tissue, and frequently has a reddish-yellowish colour. Instead of a superficial mucosal involvement, a deep localization in the soft tissues is also possible. Depending on the localization of the tumour, the diagnosis and the resulting therapy can turn out to be a challenge for the clinician. A clear differentiation to malign neoplasias of the fat tissues and other soft tissue expansions is essential. The following case report presents a female patient who is affected by a lipoma in the proximity of the mental nerve. The diagnostic work-up and resulting therapy including a review of the current literature are presented and discussed.
