title: Synchronous resection of pancreatic serous cystadenocarcinoma and liver metastasis: First reported case and review of literature.
abstract: Cystic neoplasms account for approximately 10-20% of all pancreatic cysts and 1% of pancreatic cancers. Serous cystadenomas are considered benign tumors with almost no malignant potential, and thus the management is typically only observation with serial imaging. According to the current World Health Organization classification, cases with distant metastases are defined as serous cystadenocarcinomas. To date, only 17 such cases with concomitant synchronous or metachronous liver metastasis have been described in the literature, and eight of these reports described treatment of secondary liver lesions. This report describes the first case of synchronous resection of pancreatic serous cystadenocarcinoma and liver metastasis in a 56-year-old female patient. The patient is currently well after 30 months of follow-up with no tumor recurrence or new metastatic liver nodules based on magnetic resonance imaging.
