76) In typical cases, ductular reaction is prominent and consists of a proliferation of small, interanastomosing ductules located at the periphery of the portal tracts.
These can be distinguished by immunostaining for keratin 7 and keratin 19, which highlight the presence of a ductular reaction around reactive and regenerating clusters (pseudoinvasion) as a ductular reaction is absent around tumor cells of stromal invasion (Figure 5, F).

Benign biliary lesions such as bile duct hamartoma, bile duct adenoma, and reactive bile ductular proliferation can be difficult to distinguish from metastatic adenocarcinoma (from the pancreas, for example), especially on frozen section (Figure 5, A through C).
The inflammatory subgroup with no mutations in either gene demonstrated, in addition to marked lymphohistiocytic infiltrates, cytologic atypia, reactive ductular proliferation, and dystrophic blood vessels.
73) This metaplasia is a common finding in a variety of genetically engineered mouse models and is characterized by tubular structures that have features of acinar as well as ductular differentiation.
Occasionally, the ductular transformation of acini, that is, the formation of tubular complexes, may result in closely packed clusters, but these clusters of tubular complexes are evenly shaped, evenly sized, evenly spaced, and smoothly demarcated from the surrounding fibrotic tissue.
Studies using 3-dimensional and computerized reconstruction have shown that DCIS is mainly unicentric and extends along a complex, branching ductular system, intertwining with adjacent ducts in a pyramid-like shape toward the nipple.
Histologic sections of the liver needle core biopsy specimen showed cirrhotic hepatic parenchyma with bile ductular proliferation and portal inflammatory infiltrates composed of lymphocytes, neutrophils, and a few scattered eosinophils.
In addition, the presence of the ductular component in the islet cell tumor supports the theory that the endocrine cells originated from the ductal component.
The epithelial component consisted of ductular structures of varying caliber lined by pseudostratified, columnar to cuboidal basaloid cells with hyperchromatic nuclei and brisk mitotic activity.
