Gastroscopy revealed superficial ulceration at the esophagogastric junction with irregular protrusion and a polypoidal protuberant mass in the duodenal papilla protruding into the lumen ( Figure 1 ).
MRCP results. (A) A soft tissue nodule at the end of the common bile duct with low biliary tract obstruction. (Arrow: the location of the tumor). (B) A poorly defined somatic nodule at the body of the pancreas. (Arrow: the location of the tumor).

Pancreatic magnetic resonance cholangiopancreatography (MRCP) reported soft tissue nodules at the end of the common bile duct approximately 2.6x1.7 cm in size that were prone to malignancy, with low biliary tract obstruction ( Figure 2A ). Another pancreatic somatic nodule was found in the body of the pancreas that was approximately 2.0x2.3 cm in size and poorly defined, so the possibility of malignancy could not be excluded ( Figure 2B ).
Pathological results. (A) Duodenal adenocarcinoma. (B) Moderately differentiated adenocarcinoma (Lauren classification: intestinal type) at the esophagogastric junction. (C) Pancreatic adenocarcinoma at the pancreatic body. Hematoxylin-eosin (H&E) staining of biopsy samples (40x) magnification.
