Osseous metaplasia is described in a variety of organs in both neoplastic and non-neoplastic conditions. In gastrointestinal tract, it is a very rare phenomenon. Only few cases have been reported in literature in colonic polyps especially in juvenile polyps and colonic malignancies. We report three cases of heterotopic ossification in juvenile polyp and one in colonic adenocarcinoma with review of literature. Many mechanisms of its pathogenesis are hypothesized but exact cause remains still unclear.
Key words: Juvenile polyp, osseous metaplasia, rectal polyp.
