Schwannoma of lower lip: an unusual case report and review of literature -

Schwannoma is a slow-growing benign tumor that is derived from the Schwann cells. It presents as a well-defined radiolucency in the soft tissues where it commonly occurs, and it is also found in the bones. Although schwannoma occurs as a single lesion, it presents as multiple lesion when associated with neurofibromatosis. The most preferred treatment is the conservative surgical removal. The rate of recurrence and malignant transformation are not seen very often. The histological patterns of the lesions reveal that they are well encapsulated and consist of spindle cells showing either an Antoni A (spindle cells arranged in palisaded whorls and waves) or Antoni B (spindle cells with more haphazard appearance). In this article, we review the literature on intraoral schwannoma and describe a case occurring on the lower lip of a 30-year-old male patient.
