A 67-year-old man visiting our hospital with the chief complaint of sudden upper abdominal pain was diagnosed with acute pancreatitis. Based on computed tomography findings, intraductal papillary mucinous neoplasm(IPMN)was suspected as the cause of the pancreatitis and detailed examination was conducted following its alleviation. Endoscopic retrograde and magnetic resonance cholangiopancreatography showed marked dilation of the main pancreatic duct, with a mural nodule inside the main pancreatic duct at the pancreatic head. Main duct IPMN was diagnosed and pancreaticoduodenectomy was performed 3 months after the onset of acute pancreatitis. The histopathological findings showed a tumor proliferating in a mold pattern in the lumen of the dilated main pancreatic duct, resulting in a diagnosis of intraductal papillary mucinous carcinoma(IPMC). The presence of IPMN should be considered as a cause of acute pancreatitis; if findings suggestive of IPMN are found on imaging, detailed examinations and treatment are needed in consideration of the potential for malignancy following alleviation of pancreatitis.

We report a case of intraductal papillary mucinous carcinoma(IPMC)penetrating the colon in an 82-year-old man. He visited our hospital with left upper abdominal pain. Abdominal CT showed IPMC of the pancreatic tail, measuring 7 cm, with tumor penetration to the colon and retrograde infection. After the antibacterial treatment, we performed distal pancreatectomy with colectomy. Pathological examination showed proliferation of adenocarcinoma of the gastrointestinal tract with penetration to the colon. Severe fibrosis and calcification surrounding the invasive cancer cells suggested a long disease duration. Despite adjuvant chemotherapy, he developed recurrence of peritoneal dissemination after 9 postoperative months, and subsequently, systemic chemotherapy was started. As intraductal papillary mucinous neoplasm(IPMN)might penetrate the adjacent organs, leading to a poor prognosis, even over a prolonged time period, IPMN should be followed-up appropriately and resected soon after the suspicion of malignant transformation.

A 53-year-old woman was referred to our hospital because of upper abdominal pain and expansion of the pancreatic main duct. Enhanced computed tomography revealed expansion of the main pancreatic duct from the head to the tail; in addition, a 30 mm cystic tumor was observed in the pancreatic head and a 56 mm tumor was observed in the ventral side of the pancreatic body. Endoscopy revealed fistula formation in the duodenum of the Vater papilla on the oral side. The patient was diagnosed with an intraductal papillary mucinous carcinoma(IPMC). In addition, PET-CT revealed accumulation of FDG in the ventral side of the pancreatic body, and a disseminated nodule in the omental bursa was suspected. We administered 6 courses of gemcitabine plus nab-paclitaxel therapy, after which, the tumor in the ventral side of the pancreatic body disappeared. We then performed sub-stomach-preserving pancreatoduodenectomy. The results of abdominal cavity washing cytology were negative, and there were no disseminated nodules in the omental bursa. Therefore, we could perform R0 excision.
