Abstract
We report 2 cases of pseudomyxoma peritonei (PMP) combined with an intraductal papillary mucinous neoplasm (IPMN) and a review of the literature. In both cases, PMP emerged after surgical resection of the IPMN. In one case, neoplastic foci were present in the surgical margin and PMP was found 1 year after the initial resection, while PMP emerged 5 years after surgical resection in the other case. Including these 2 cases, 8 cases of PMP arising from IPMN have been reported. This condition occurs more frequently in males (7 males, 1 female), while the age at diagnosis ranges from 49 to 82 years, with a mean of 63.3 years. IPMNs occur more commonly in the tail of the pancreas (62.5%). Two different patterns regarding the mechanism of PMP arising from IPMN have been indicated; a rupture of the pancreatic duct, after which the neoplasm spreads through the fistula into the peritoneal cavity, and post-surgical development of PMP after insufficient surgical treatment for an IPMN. Our findings indicate that attention must be given to avoid mucous leakage and obtain a negative surgical margin during surgical treatment of an IPMN.
