[A case of successful resection for recurrent intraductal papillary mucinous adenocarcinoma].

Intraductal papillary-mucinous neoplasms (IPMN) of the pancreas have recently been defined and classified by the World Health Organization. In addition, many cases of IPMN continue to be recognized frequently. We report a case of a 65-year-old female who underwent surgical resection of the pancreas twice within a period of 6 months for primary and recurrent IPMN. We first performed distal pancreatectomy with splenectomy for IPMN in the pacreatic body. A histopathological study revealed invasive adenocarcinoma and the negative margin of the pancreatic duct. A cystic mass in the uncinate process of the gland was identified by CT scan 6 months after the initial surgery. Complete pancreaticoduodenectomy was performed. Recurrent IPMN consisted of adenosquamous cell carcinoma. She currently is alive without evidence of disease at 3 years from the second resection. Recurrent disease in the residual pancreas suggests that a long-term surveillance is critical.
