Juvenile Rectal Polyp with Osseous Metaplasia - A Rare Case with Review of Literature
Heterotopic bone formation (osseous metaplasia) is rarely detected in the gastrointestinal tract. We report a unique case of juvenile rectal polyp occurring in a 5 year old female child which showed osseous metaplasia. This phenomenon is detected at histology but has no clinical significance. Literature with regard to the pathogenesis of osseous metaplasia is reviewed.
