ABSTRACT Adenomyoma is a term generally applied to nodular lesions showing proliferation of both epithelial and smooth muscle components. Despite its benign nature, ampullary adenomyoma is usually presented as biliary obstruction. Most cases are misdiagnosed as carcinoma or adenoma by preoperative endoscopic or radiologic procedure. Therefore, it is frequently treated with extensive surgery. To our knowledge, this is the first reported case in English literature of adenomyoma located in the peripancreatic orifice resulting in intermittent pancreatic duct obstruction and recurrent pancreatitis diagnosed by the endoscopic piecemeal resection.

    ABSTRACT: Adenomyoma of the small intestine is an extremely rare condition characterized by abnormal glandular structures surrounded by smooth muscle. We report a case of adenomyoma of the jejunum. The patient was a 61-year-old female with cancer of the sigmoid colon and multiple liver cysts, who was sent to the operation room for exploratory laparotomy and sigmoidectomy. At surgery, a polypoid lesion was incidentally found in the lower jejunum, which was resected. On histologic examination, the morphologic features were typical of adenomyoma. However, new histopathological and immunohistochemistry features are described here, providing evidence that adenomyoma of the jejunum is a form of intestinal epithelial hamartoma.

    ABSTRACT: 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.

    ABSTRACT: Acute recurrent pancreatitis still poses diagnostic difficulties. The coexistence or moreover the causative relationship of carcinoma of the ampulla of Vater and acute recurrent pancreatitis is fairly rare. We present a case of carcinoma of the ampulla of Vater that presented with acute recurrent necrotizing pancreatitis complicated with pseudocysts. A diagnosis of malignancy in the ampulla was only made after several ERCP attempts due to residual inflammation at the periampullary area. Malignancy at the ampulla of Vater causing recurrent episodes of pancreatitis represents a realistic risk and attempts to diagnose the underlying cause should always take into account the possibility of cancer.
