There are many clinical and histological problems in mucin producing pancreatic cancer (MPPC). We experienced a case of cystic adenocarcinoma of the pancreas in a 73 year-old woman, in whom the main pancreatic duct was dilated as in MPPC. Several examinations revealed that she had pancreatic cancer which was diagnosed as MPPC and we performed a pancreaticoduodectomy. We could not observe a tumor in the main pancreatic duct of the specimen, but we found a papillomatous tumor in a cystic dilatation of the pancreas head. It was it is unclear if these cystic dilatations were from a branch of the pancreatic duct or not. The histological diagnosis was cystadenocarcinoma. According to TNM Post Surgical Histopathological Classification, this cancer was pT2, pN0, pM0, stage I. It is difficult to decide whether this was a case of MPPC or cystadenocarcinoma of the pancreas communicating with the main pancreatic duct. But these two diseases could be categorized as mucinproducing pancreatic tumor.
