title: [Cystic neoplasm diagnosed as pancreatic pseudocyst: report of 5 cases and review of the literature].
abstract: The majority of cystic lesions of the pancreas are pseudocysts. Nine to thirteen per cent of pancreatic cyst are neoplastic, benign or malignant. Failure to recognize neoplastic nature of a cyst leads to an improper management. The authors present five cases of cystic tumors mistaken for pancreatic pseudocysts, including three mucinous cystadenomas and two mucinous cystadenocarcinomas. Four were drained by cystojejunostomy and one cystogastrostomy. One patient with no metastases at first operation had metastatic spread at reoperation. In the other four cases, subsequent resection was possible and probably curative. Review of the literature and guidelines are given for the purpose of differential diagnosis between theses entities.
