Abstract

Schwannomas, benign neural sheath tumors, are mostly located at head and neck region on the cranial nerves and sympathetic nerves as solitary lesions. Most of the cases are asymptomatic and can be detected in any age and gender. Imaging modalities such as magnetic resonance imaging and computer tomography may be suggestive for diagnosis but pathologic diagnosis is sometimes difficult with fine needle aspiration biopsy. The treatment modality is surgical excision of the mass via enucleation or total excision. We represent a hypoglossal nerve schwannoma in submandibular region of a 39-year-old female patient who was treated successfully with extracapsular excision without any recurrence during one-year follow-up.
