Surgical management of recurrent malignant schwannoma of the scalp

Abstract

Localization of malignant schwannoma in the head and neck region is rare. Malignant schwannoma is a highly aggressive, slowly growing, encapsulated tumor of nerve sheath origin. The most common presentation of this tumor is a subcutaneous progressively enlarging mass with or without neurologic symptoms. These tumors arise from neurofibromas with or without von Recklinghausen disease, and most of the remains develop from peripheral nerve trunks. We report a case with recurrent malignant schwannoma of the scalp that is an uncommon presentation and discuss the clinicopathologic properties of this tumor. Copyright © 2011 by Mutaz B. Habal, MD.
