Osseous Metaplasia in Rectal Polyp: A Case Report with Review of Probable Pathogenesis

Azar Naimi et al. Adv Biomed Res. .

Abstract

Heterotopic bone formation is a rare event in gastrointestinal lesions, especially in the pediatric population. Osseous metaplasia is exceedingly rare in colonic polyps. We present a case of rectal juvenile polyp with stromal osseous metaplasia in a 10-year-old male child. This histologic finding is very rare in children with colorectal polyps.

Keywords: Juvenile; osseous metaplasia; pediatric; rectal polyp.
