Benign fibroblastic polyp of the colon: a case report.

There are a fair number of polyps in the gastrointestinal tract, which cannot be classified under a certain category. We report herein a 50-year-old man with a 6-mm sigmoidal polyp; he had been operated previously for rectal carcinoma. The polyp was characterized by benign-appearing spindle cells in the lamina propria leading to a wide separation and disorganization of the colonic crypts, accompanied by focal erosion and restricted areas suspicious for inflammatory fibroid polyp. The histologic features were found consistent with the disease spectrum of 'benign fibroblastic polyp of the colon' defined by Eslami-Varzaneh et al. The case is presented with a review of the literature and differential diagnostic considerations.
