Abstract

A solitary pedunculated gastric polyp in the gastric fundus was removed from an asymptomatic 36-year-old woman with normal gastric acid secretion and a normal serum gastrin level. This lesion exhibited distinctive histological features including prominent proliferation of pseudopyloric glands, fundic glands, foveolar epithelium and a fibromuscular stroma. Moreover, its surface was entirely covered by a layer of normal gastric epithelium. Biopsies of the background mucosa taken from the gastric fundus revealed only mild superficial gastritis. A gastric gland heterotopia was diagnosed because of its unique morphology.

摘要

一名36岁无症状女性，胃酸分泌正常，血清胃泌素水平正常，其胃底有一个带蒂的孤立性胃息肉被切除。该病变具有独特的组织学特征，包括假幽门腺、胃底腺、小凹上皮和纤维肌性间质显著增生。此外，其表面完全被一层正常胃上皮覆盖。取自胃底的背景黏膜活检仅显示轻度浅表性胃炎。因其独特的形态，诊断为胃腺异位。
