Schwannoma of the urinary bladder waa : a case report / 대한비뇨기과학회지

ABSTRACT

Schwannoma, also referred to as neurilemmoma, neurinoma, and perineural fibroblastoma, is the most frequent solitary tumor of the peripheral nerves. It is an encapsulated sheath tumor consisting or two components a highly ordered cellular component( Antoni A area) and a loose, myxoid tomponent( Antoni B area ). It is usually solitary and may be benign or malignant, solid or cystic, encapsulated or diffuse. It rarely occurs in the retroperitoneal space. We report a very rare case of Schwannoma developed in the muscular layer of the bladder wall and review the relevant literatures.
