Adenomyoma is a rare benign lesion occurring commonly in the fundus of the gallbladder in the biliary tract. Ampullary adenomyoma is rarer still, presenting as obstructive jaundice due to its location at the ampulla and may mimic malignancy on clinical and radiological examination. Endoscopic biopsy may not be always diagnostic if the lesion is deep seated. Histologically these lesions show a combination of diverse benign epithelial and mesenchymal elements, which should not be confused with an invasive tumor because of its arrangement. We report three cases of adenomyoma located at the ampulla presenting as obstructive jaundice. The diagnosis was confirmed on pacreaticoduodenectomy resection specimens.
腺肌瘤是一种罕见的良性病变，常见于胆道系统的胆囊底部。壶腹腺肌瘤更为罕见，因其位于壶腹部可导致梗阻性黄疸，在临床和影像学检查中可能类似恶性肿瘤。如果病变位置较深，内镜活检不一定总能明确诊断。从组织学上看，这些病变表现为多种良性上皮和间充质成分的组合，由于其排列方式，不应与浸润性肿瘤相混淆。我们报告3例位于壶腹部表现为梗阻性黄疸的腺肌瘤病例。诊断在胰十二指肠切除标本上得到证实。
