| [ Summary ] | Serous cystadenocarcinomas of the pancreas are often difficult to diagnose preoperatively, since they give non-specific findings through images of cystic lesions, and have subtypes such as macrocystic, oligocystic, multiple and multinodular types. Six cases of serous cystadenomas or cystadenocarcinomas with malignant histopathological findings have been reported. Therefore, strategies for treatment of microcystic adenomas are not uniform. According to six such cases with malignant findings, tumors measuring more than 10cm, involving ducts and vessels, and having a multinodular appearance are often associated with malignant histopathological f indings. We believe that a microcystic adenoma measuring more than 4cm in diameter should be recommended for resection, wheather it is located in the pancreatic head or not. | |
