NONINVASIVE MUCINOUS CYSTADENOCARCINOMA - A 16-YEAR COURSE

A 26-year-old woman was operated on because of a suspected infectious pseudocyst of the pancreas. A Large cyst was found on the body of the pancreas. During laparotomy a biopsy specimen was taken from the cysti c wall, but no evidence of a tumor was obtained. On the ba sis of thes e intraoperative findings, a cystogastrostomy was performed and the pa tient had an uneventful postoperative course. The patient presented 8 years later with a recurrent cyst and was operated. As there was a sus picion of a cystic neoplasm, total resection of the cyst was performed . Based on the histological findings a noninvasive mucinous cystadenoc arcinoma of the pancreas was diagnosed. We believe that from the begin ning this cyst was a noninvasive mucinous cystadenocarcinoma. Followin g the complete resection the clinical course was favorable for 8 more years without evidence of recurrence or metastases.
