BENIGN FIBROUS HISTIOCYTOMA OF THE STOMACH - REPORT OF A CASE

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 biopsie s failed to demonstrate the nature of the tumor. Histopathologic inves tigation of the resected tumor showed the typical features of benign f ibrous histiocytoma: Consisting of an admixture of spindly fibroblast- like and roundish histiocyte-like cells ar ranged in a storifirm patte rn. Furthermore, immunohistochemical staining with alpha-1-antichymotr ypsin 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.
