Abstract

A sixties woman was found to have a about 25mm gastric submucosal tumor (SMT) on the anterior wall of the antrum on esophagogastroduodenoscopy (EGD) , which had not been observed on EGD one year previously. Endoscopic ultrasonography (EUS) showed that the SMT was a heterogenous and echogenic lesion with an anechoic area and it was mainly located in the third layer. Endoscopic submucosal dissection (ESD) was performed in order to diagnose the tumor.
Pathological examination revealed heterotopic gastric glands (HGG) with hyperplastic mucosa. HGG are sometimes accompanied by gastric cancer. Our case was not complicated with gastric cancer.
We experienced a case of HGG whose size increased rapidly within one year, in which ESD was performed in order to obtain a diagnosis.
