Serous and mucinous cystadenoma/cystadenocarcinoma of the pancreas.

Twenty cases of cystic pancreatic neoplasms were examined over a 10-year period by the Department of Radiology, University Hospital, Lund, Sweden. Four patients had serous cystadenoma, seven had mucinous cystadenoma, and seven had mucinous cystadenocarcinoma. One patient had a mucin-producing ductal carcinoma, and one patient had a benign mucus cyst. The various types of tumor are illustrated, and the difficulty in differentiating the subtypes is stressed.
