Anaplastic carcinoma occurring in association with a mucinous cystic neoplasm of the pancreas.

Anaplastic carcinomas of the pancreas are considered variants of ductal adenocarcinoma. They typically occur in elderly men. They have rarely been reported to occur in association with mucinous cystic neoplasms of the pancreas. We report a case of anaplastic carcinoma occurring in association with a pancreatic mucinous cystic neoplasm, borderline-type, in a 25-year-old woman who presented with lymph node and hepatic metastases.
