Abstract

A solitary pedunculated polyp of the oxyntic mucosa removed from a 66-year-old patient with atrophic gastritis and achlorhydria exhibited distinctive histological features consisting of submucosal, mostly oxyntic-type glands with a smooth muscular framework. Histochemical and immunohistochemical studies demonstrated that the glands were composed of well differentiated chief, parietal, and endocrine cells. Moreover, less frequent glands of the antro-pyloric type were also seen. The lesion was regarded as a previously unrecognized variety of gastric hamartoma.

摘要

从一名患有萎缩性胃炎和胃酸缺乏症的66岁患者的胃体黏膜中切除的一个带蒂孤立性息肉，呈现出独特的组织学特征，包括黏膜下层主要为胃体型腺体且有平滑的肌性框架。组织化学和免疫组织化学研究表明，这些腺体由分化良好的主细胞、壁细胞和内分泌细胞组成。此外，还可见较少见的胃窦 - 幽门型腺体。该病变被认为是一种先前未被认识的胃错构瘤类型。
