title: Benign fibrous histiocytoma of the stomach: report of a case.
abstract: We report herein an extremely very rare case of primary benign fibrous histiocytoma of the stomach found in a 56-year-old man who presented with a 2-week history of nausea and anorexia. Gastrointestinal X-rays and endoscopy revealed a protruding lesion in the stomach, but biopsies failed to demonstrate the nature of the tumor. Histopathologic investigation of the resected tumor showed the typical features of benign fibrous histiocytoma: Consisting of an admixture of spindly fibroblast-like and roundish histiocyte-like cells arranged in a storiform pattern. Furthermore, immunohistochemical staining with alpha-1-antichymotrypsin was positive for histiocyte-like cells in the tumor. The patient has shown no evidence of recurrence in the 2 years of follow-up since his operation.
