Abstract

Pancreatic ductal adenocarcinoma (PDAC) represents the most common neoplasm of the pancreas. PDAC is an infiltrating tumor of epithelial origin forming glandular, duct-like structures. Histological subtypes of PDAC exist, and classification is performed according to the WHO classification system, mainly taking into account histomorphological criteria and marker profiles. Recent studies have shown a great deal of morphological heterogeneity in PDAC, which to some extent correlates with a distinct molecular pathogenesis and a different prognosis. However, a clear-cut correlation between morphologic and molecular subtypes is still missing. In this chapter, we provide an overview of the gross, histomorphological, and immunohistochemical characteristics of PDAC. Furthermore, we discuss its different variants according to emerging concepts of tumor heterogeneity in this entity.
