Abstract

Osseoz metaplazi, heterotopik kemik oluşumudur ve gastrointestinal sistemde, özellikle benign lezyonlarda nadiren karşılaşılır. Patofizyolojisi net olarak bilinmemekle birlikte bazı teoriler öne sürülmüştür. Bu olgu sunumunda, 7 yaşında bir kız çocuğunda rektal kanama ile bulgu veren kemik metaplazili inflamatuar rektal polip olgusunu sunduk. Aynı zamanda literatürü taradık ve kolon poliplerinde osseoz metaplazi olgularını özetledik. Sunulan vakalarda bunun spesifik bir antite olabileceğini düşündürten, bazı benzerlikler saptadık. Kolorektal poliplerde osseoz metaplazi oldukça nadirdir. Saptadığımız kadarıyla olgumuz osseoz metaplazi içeren on birinci rektal inflamatuar polip vakasıdır. Kolon poliplerinde osseoz metaplazi hem klinik hem de prognoz üzerinde önemli bir etkiye sahip olmasa da, mikroskopik incelemede karşılaşıldığında kafa karıştırıcı olabilir.

Inflammatory Rectal Polyp with Osseous Metaplasia: Is It a Distinctive Disease Entity?

Abstract

Osseous metaplasia is a heterotopic bone formation and it is encountered rarely in the gastrointestinal tract, especially in benign lesions. Although its pathophysiology is not known clearly, there are several theories suggested. In this case report, we presented a case of bone formation in a rectal inflammatory polyp presenting with rectal bleeding in a 7-year-old girl. Therewithal, we reviewed the literature and summarized the subject of osseous metaplasia in colon polyps. We detected some similarities in the cases presented that suggest it might be a distinctive disease entity. Osseous metaplasia in colorectal polyps is extremely rare. To our knowledge, this is the eleventh reported case of osseous metaplasia in a rectal inflammatory polyp. Although osseous metaplasia in colon polyps has not a significant effect on both clinic and the prognosis, it can be confusing when encountered in microscopic examination.
