Schwannoma of the upper lip: a case report.

Schwannomas are neurogenic tumors that arise from the Schwann cells of the nerve sheath. They are benign, usually solitary, and encapsulated neoplasms. In this report, a 29-year-old woman with a complaint of painless swelling in the upper lip is presented. Computed tomography showed a well-circumscribed solid mass. The lesion was excised and histopathologic diagnosis was made as schwannoma. The postoperative course was uneventful. No recurrence was observed during a follow-up period of 12 months.
