Gastric adenomyoma is a rare benign tumor composed of epithelial structures and smooth muscle stroma. Here, we report an unusual case of gastric adenomyoma mostly composed of smooth muscle that was incidentally found during a laparoscopic intervention. On radiology, it mimicked an acquired hypertrophic pyloric stenosis in an adult patient, and pathologically it resembled a pure smooth muscle hamartoma. Complete submission of the lesion for histology was necessary to find the epithelial component and make the right diagnosis. As a mimicker of benign and malignant entities, gastric adenomyoma is usually an unexpected finding after surgery. The aim of this report is to analyze this adenomyoma variant in the setting of an unexplained thickening of the gastric wall, with explanations concerning histogenesis and biological potential.
胃腺肌瘤是一种罕见的良性肿瘤，由上皮结构和平滑肌基质组成。在此，我们报告一例不寻常的胃腺肌瘤病例，该病例主要由平滑肌组成，在腹腔镜手术中偶然发现。在影像学上，它在成年患者中类似获得性肥厚性幽门狭窄，而在病理上它类似纯平滑肌错构瘤。为了找到上皮成分并做出正确诊断，将病变完整送检做组织学检查是必要的。作为良性和恶性病变的模仿者，胃腺肌瘤通常是手术后意外发现的。本报告的目的是在胃壁不明原因增厚的情况下分析这种腺肌瘤变体，并对其组织发生和生物学潜能进行解释。
