Abstract
We report a case of schwannoma of the left lower lip in a 17-year-old female. A schwannoma is a tumor thought to be derived from Schwann cells and is rarely seen in the lip. On initial visual and palpation examination, a nodular, elastic hard, mobile mass was found on the left lower labial mucosa, which was suspected to be a benign tumor. Contrast-enhanced magnetic resonance imaging （MRI） showed a homogeneous contrast effect on T1-weighted images, negating malignant findings. Aspiration cytology showed no atypical cells. There was no rapid growth of the tumor during follow-up. The patient was diagnosed as having a benign tumor of the lower lip and the tumor was enucleated under local anesthesia. The pathological diagnosis was an Antoni A-type schwannoma. The patient is progressing well with no postoperative motor or sensory deficits.
