Intraductal tubular neoplasms are rare. We report a case highlighting clinicopathological features of such neoplasms. A 62-year-old man referred for acute pancreatitis was found in contrast-enhanced computed tomography to have a low-density area slightly enhanced in the pancreatic body. The distal main pancreatic duct (MPD) was dilated. MRCP and ERCP showed a small MPD filling defect. Cytologically, pancreatic juice at ERCP was Class IV. Based on intraductal tubular carcinoma or ductal carcinoma suspected from these findings, we conducted distal pancreatectomy. Macroscopically, the MPD was dilated to 7mm in diameter and filled by a polypoid tumor 6mm in diameter, histologically diagnosed as intraductal tubular carcinoma.
