Abstract

BACKGROUND/AIMS: Since 1980 a group of pancreatic tumors have been termed intraductal papillary mucinous tumors (IPMT). Controversy about the term and clinico pathologic entity still exist. This study compared the clinicopathlogic features, imaging, prognostic differences between mucinous cystic tumors (MCT) and intraductal papillary mucinous tumors (IPMT) of pancreas.
METHODS
We reviewed 7 operated patients between January of 1997 to December of 2000, retrospectively by clinical record. 4 patients with mucinous cystic tumors and 3 patients with intraductal papillary mucinous tumors.
RESULTS
Gender, age, symptoms, signs, tumor location and size, the presence or abscece of communication with the pancreatic duct differed between two types. Mucinous cystic tumors showed single cyst, located in pancreatic tail. Intraductal papillary mucinous tumor showed pancreatic duct dilatation & mucin plug, located in pancreatic head & body. 4 patients of mucinous cystic tumor were received distal pacreatectomy. 2 patients of intraductal papillary mucinous tumor received pancreaticoduodenectomy. 1 patient of intraductal papillary mucinous tumor received distal pancreatectomy.
CONCLUSIONS
Mucinous cystic tumors and Intraductal papillary mucinous tumors were different clinicopathologic entities. Complete resection should be attempted for these mucin producing tumors.
