Gangliocytic paraganglioma of duodenum

An elderly person, aged 60 years, presented with pain abdomen localized to the epigastric region, of one year duration. There was a past history of a single episode of passing black-colored tarry stools and hematemesis. Ultrasonography (USG) of abdomen reported a suspected duodenal / periampullary growth. Biopsy performed was inconclusive. Contrast enhanced computerized tomography (CECT) scan abdomen suggested suspected submucosal leiomyoma of duodenum with intrahepatic biliary dis-tension. Whipple's procedure was performed which recovered a growth measuring 6x5x5cms arising in periampullary region of second part of duodenum. Pancreatic duct and common bile duct (CBD) were dilated. The histopathological findings were suggestive of neuroendocrine tumor of duodenum. The diagnosis of gangliocytic paraganglioma was confirmed by immunohistochemical stains.
