Abstract
- Plexiform neurilemmoma is a rare variant of neurilemmoma characterized by a multinodular growth pattern which is originated from Schwann cells. Neurilemmoma most commonly occurs in the head, neck, and flexor surface of the extremities. Neurilemmoma also takes place in the oral cavity. Amongst the oral cavity, the tongue is frequently involved, but the lip rarely. To our knowledge, there has been one report in Korean dermatologic literature presenting a classical form of neurilemmoma on the upper lip. We report here in a case of plexiform neurilemmoma that showed typical histologic findings on the upper lip of a 37-year old woman. We present this rare case and review the literature briefly concerning neurilemmoma. Even though a plexiform neurilemmoma of the upper lip is very rare, it should be taken into consideration in the differential diagnosis of a lip mass.
