Safe endoscopic resection of gangliocytic paraganglioma of the major duodenal papilla.

Gangliocytic paraganglioma of the duodenal papilla associated with esophagogastric adenocarcinoma.

A 3-cm painless epigastric mass was found on examination in 53-year-old man with abdominal pain and vomiting for the past 6 months. An abdominal computed tomography (CT) scan showed asymmetric thickening of the distal esophagus, and upper endoscopy showed a neoplastic lesion in the distal esophagus (histological examination of the biopsy revealed adenocarcinoma).

Gangliocytic Paraganglioma of the Minor Papilla of the Duodenum

A duodenal polyp was found during a health check of a 71-year-old asymptomatic man. Duodenoscopy demonstrated a pedunculated, smooth-surfaced tumor of 18 mm in size, protruding from the minor papilla. Endoscopic ultrasonography demonstrated a homogeneously low-echoic submucosal tumor. Enhanced computed tomography and magnetic resonance imaging demonstrated a well-enhanced duodenal tumor without...
