Pancreatic pathology: A practical review

Abstract

Given advances in diagnostic imaging and surgical technique, a variety of neoplastic and non-neoplastic pancreatic lesions are increasingly encountered in clinical practice. The distinction of these lesions has significant therapeutic and prognostic implications. Herein, we review the major clinicoepidemiologic and pathologic features of ductal adenocarcinoma, pancreatic cystic neoplasia, pancreatic endocrine tumor, and related lesions. Emphasis is placed on frozen-section diagnosis and differential diagnostic features. Also, potential diagnostic pitfalls are highlighted, such that they may be avoided.
