Abstract

Introduction:
Schawannomas (neuromas, neurilemmomas) are benign tumors originating from showann cells or nerve fiber sheet cells. They are solitary, encapsulated tumors usually attached to, or surrounded by a nerve.
Case Report:
We present a case of left hypoglossal nerve schwannoma in a 19 year old man who was admitted with progressive left tongue atrophy.
Conclusion:
Schwannoma of the hypoglossal nerve usually develops in the intracranial and extracranial portion or both in the intracranial and extracranial components forming a dumbbell shape tumor .The peripheral hypoglossal schwannomas are extremely rare.
