Two cases of duodenal paragangioliomas that were studied using light microscopy and immunocytochemical methods are reported. The tumors showed immunoreactivity to somatostatin, cholecystokinin, calcitonin, gastrin, vasoactive intestinal polypeptide, serotonin, met-enkephalin, leu-enkephalin, and substance P. The similarities of duodenal paragangioliomas to other neoplasms occurring in similar anatomic locations are outlined.
