Abstract

INTRODUCTION

Heterotopic bone is rarely found in the gastrointestinal tract. Here we report a rare case of metaplastic ossification within a benign ulcerating adenoma and review the literature concerning the aetiology.

CASE PRESENTATION

A 63-year-old woman, who presented with a history of melaena, was found at colonoscopy to have a pedunculated ulcerating polyp. Histological examination demonstrated multiple areas of osseous metaplasia within the polyp stroma.

CONCLUSION

Heterotopic ossification in colonic adenomas is a particularly rare phenomenon, with the majority of cases occurring within malignant lesions. The suggested mechanisms for its aetiology still remain unclear.

摘要

引言

胃肠道中很少发现异位骨。在此,我们报告一例罕见的良性溃疡性腺瘤内化生骨化病例,并回顾有关病因的文献。

病例介绍

一名63岁女性,有黑便病史,结肠镜检查发现有一个带蒂的溃疡性息肉。组织学检查显示息肉基质内有多个骨化生区域。

结论

结肠腺瘤中的异位骨化是一种特别罕见的现象,大多数病例发生在恶性病变中。其病因的推测机制仍不清楚。
