Solid and papillary epithelial neoplasm of the pancreas.

Abstract

Solid and papillary epithelial neoplasm of the pancreas is an uncommon low grade malignant tumor histologically distinct from the usual ductal adenocarcinoma and amenable to cure by surgical excision. It tends to occur in black women in their second or third decade of life and has often been misclassified as nonfunctional islet cell tumor or as cystadenoma or cystadenocarcinoma. Twelve cases were reviewed. Sonography and CT of solid and papillary epithelial neoplasms depict a well-demarcated mass that can be solid, mixed cystic and solid, or largely cystic. The radiologic appearance is dependent on the maintenance of the integrity of the neoplasm versus the extent of retrogressive changes that have occurred.
