Schowannoma in an Uncommon Site, Upper Lip: A Case Report
Schwannoma is one of the most common benign intracranial tumors which originates from the Schwann cells of neural sheaths in the upper part of vestibular branch of the eighth nerve, especially in patients with neurofibromatosis type 2. Schwannoma in the other parts of head and neck region is, however, relatively uncommon.The present report describes a rare case of schwannoma that was accidentally discovered in the upper lip in asymptomatic patient lasting for more than 10 years with recently size enlargement. Schwannoma could be seen in a variety of anatomic sites. Thus, this diagnosis should be considered in the differential diagnosis of soft tissue tumor in any location.
