We report a case of gastric adenomyoma in a 1-month-old girl. This patient presented with gastric outlet obstruction simulating infantile hypertrophic pyloric stenosis. Histologic examination of the excised specimen showed irregularly arranged glands and interlacing smooth muscle bundles surrounding the glandular elements. We suggest that this lesion is not just heterotopia, but hamartoma composed of abnormal mixture of endoderm-derived epithelial component and mesoderm-derived smooth muscle.
我们报告一例1个月大女童的胃腺肌瘤。该患者表现为胃出口梗阻，类似婴儿肥厚性幽门狭窄。切除标本的组织学检查显示腺体排列不规则，且围绕腺性成分有交错的平滑肌束。我们认为该病变不仅仅是异位，而是由内胚层来源的上皮成分和中胚层来源的平滑肌异常混合组成的错构瘤。
