Benign Solitary Schwannoma of the Cheek: A Case Report and a Review of the Literature.

Abstract

Schwannomas are generally known to be benign tumors that arise from Schwann cells. The most frequently encountered tumors of this type in ENT are vestibular schwannomas or acoustic neuromas. However, head and neck localization, although rare, has been documented in the literature. We present the case of a 13-year-old girl who presented with chronic swelling of the left cheek, leading to aesthetic discomfort. Clinical examination objectified a palpable swelling on both the external and internal sides of the left cheek. No other abnormalities were detected during the clinical examination. Ultrasound of the soft tissues identified the left cheek swelling as corresponding to a subcutaneous cyst. No further investigations were indicated for this patient. The treatment consisted of surgical excision via an intraoral approach with an internal buccal incision. Histological analysis confirmed the diagnosis of schwannoma. Schwannoma, a benign neurologic tumor, is rarely located in the face, particularly in the jaw. Its diagnosis is confirmed through histopathological examination, and treatment typically involves complete surgical removal when feasible.
