A Case of Multiple Hypoglossal Neurilemmomas in the Submandibular Space / 대한이비인후과학회지

ABSTRACT

Neurilemmoma is a benign tumor which is known to originate from the myelin-producing Schwann cells of the spinal nerve root, peripheral nerve and all kinds of cranial nerves except the optic nerve and olfactory nerve. Approximately, 25% to 40% of all neurilemmomas are found in the neural structures of the head and neck. Neurilemmoma of the 12th cranial nerve is rare ; multiple neurilemmoma is even more rare. Recently, the authors experienced a case of multiple (x3) hypoglossal neurilemmoma in the submandibular space. The tumor was removed completely and verified histopathologically as neurilemmoma.
