  • Abstract
  • Look Inside

 A 52-year-old woman, asymptomatic, was seen because of a small tumorous lesion in the pancreatic head demonstrated by conventional ultrasonography. Endoscopic ultrasonography (EUS) showed a tumor mass in the dilated pancreatic duct. Endoscopic retrograde pancreatography (ERP) also revealed a tumor located within a cystically dilated branch duct of the head of the pancreas. Peroral pancreatoscopy (PPS) was performed to further elucidate the nature of the lesion. It was shown as a pink-reddish papillary tumor by PPS. Examination of biopsy specimen obtained under direct observation revealed papillary adenocarcinoma of the pancreas.

 Pancreatoduodenectomy was performed. Examination of the resected materials showed papillary tumor, 18×15×13 mm in size, in the first branch of the pancreatic duct. Histologically, the tumor proved to be an adenoma with severe dysplasia containing focal malignant change.
