Abstract

Schwannoma, also known as a neurilemmoma, is a benign neurogenic tumor that arises from Schwann cells of the nerve sheath. Usually, it occurs as a slowly-growing, well-circumscribed solitary nodule on the head and neck, trunk, or extremities. However, it is rare on the oral mucosa, especially on the lip. Histologically, the lesion is characterized by an encapsulated nodule that consists of Antoni A cellular tissues with verocay bodies, and Antoni B loose myxoid tissues. Herein, we report a case of a schwannoma of the upper lip, which is a rare location
