In the early stages of chronic pancreatitis, the parenchyma exhibits an increase in connective tissue around the ducts and between the lobules. The degree of inflammation is minimal to moderate, consisting mostly of T lymphocytes, and a patchy, focal process unevenly affects the pancreas. With increasing severity, the connective tissue progresses between the acini, which gradually become distorted and tend to disappear. In advanced disease, fibrous tissue replaces the acinar tissue, and the pancreas becomes contracted, small, and hard. The islets of Langerhans are relatively spared until very late in the disease process.
