title: Adenomyoma of ampulla: a rare cause of obstructive jaundice.
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.
