Overview

Pathophysiology

  • Chronic pancreatitis is a progressive inflammatory process leading to irreversible structural damage to pancreas resulting in exocrine and endocrine dysfunction[1]
  • The pathogenesis is still unclear but two findings consistently seen in the pathogenesis of chronic pancreatitis are:
    • Protein hypersecretion resulting in proteinaceous ductal plugs leading to ductal blockage and obstruction[2]
    • Patchy inflammatory lesions in exocrine pancreas seen on microscopic examination

Genetics

  • [Disease name] is transmitted in [mode of genetic transmission] pattern.
  • Genes involved in the pathogenesis of [disease name] include [gene1], [gene2], and [gene3].
  • The development of [disease name] is the result of multiple genetic mutations.

Associated Conditions

Gross Pathology

  • Patchy focal disease
  • Fibrosis

Microscopic Pathology

  • On microscopic histopathological analysis:
    • Patchy focal disease characterized by a mononuclear infiltrate
    • Fibrosis
