A case of retroperitoneal schwannoma with histological features of gastrointestinal (GI) schwannomaoccurring in a 67-year-old woman is reported. The tumor was composed of spindle cells withfocal pseudoatypism and it showed several features typical of gastrointestinal-type schwannomasuch as lymphocytic infiltration, peripheral cuff of lymphocytes, lack of Antoni A pattern, andabsence of thick walled vessels. Immunohistochemically, the tumor showed diffuse reactivity forS100 protein and glial fibrillary acidic protein. The authors discuss a phenotypical similarity ofthe lesion with GI schwannoma as well as the possible existence of GI-type schwannoma outsidethe tubal GI tract.
