* Context.--Perineuriomas are benign peripheral nerve sheath neoplasms composed of perineurial cells with characteristic immunohistochemical and ultrastructural features. They have been traditionally classified into two main types according to their location--intraneural and extraneural--and overlap histologically with many other tumors, which may be diagnostically challenging to general surgical pathologists.

Objective.--To review the clinical, morphologic, immunohisto...
