ABSTRACT

Schwannoma also referred to as neurilemmoma, neurinoma, and perineural fibroblastoma, is an encapsulated nerve sheath tumor consisting of two componentsa highly ordered cellular component (Antoni A area) and a loose, myxoid component (Antoni B area). It is usually solitary and may be benign or malignant, solid or cystic, encapsulated or diffuse. It is rarely occur in the retroperitoneal space. The term cellular Schwannoma is indicative of a Schwannoma composed predominantly of Antoni A type tissue. We report one case of retroperitoneal with brief review of literatures.
