Intraosseous Schwannoma of the Mandible - A Case Report

Schwannomas, originally called neurilemmoma, are benign and slow growing peripheral nerve sheath neoplasms. They originate from Schwann cells, which are the myelin depositing cells of the peripheral nervous system, thus deriving its name. They can be found in both soft tissue and bone. When found within bone, they are referred to as intraosseous, or central, schwannoma. Intraosseous lesions are exceptionally rare, representing less than 1% of all primary tumors of the jaws. Conservative excision is the treatment of choice and is associated with a near 100% cure rate. Although extremely rare, schwannomas can undergo malignant transformation. The aim of this report is to describe an additional intraosseous schwannoma of the mandible and provide further literal review literature on this rare entity.
