Pathology – Chronic Pancreatitis
chronic pancreatitis is defined as a prolonged inflammation of the pancreas that causes irreversible loss of function.Chronic pancreatitis can closely resemble pancreatic cancer in clinical, radiological, and pathological aspects.
Epidemiology • Uncommon
. Aetiology: • Most instances are linked to alcohol abuse. • A tiny percentage are suspected to be autoimmune in nature.
Pathogenesis: • Chronic inflammation in the pancreas causes the replacement of functional tissue by fibrous scar tissue. Symptoms include persistent upper abdomen pain and weight loss, as well as late-onset steatorrhea and diabetes mellitus due to gland destruction.
Macroscopy: • The pancreas is replaced by fibrous tissue, resulting in dilated ducts and calcification. 2 The scarred mass can nearly resemble cancer when viewed from a macro perspective.
Histopathology reveals persistent immune cell infiltration in the pancreas, resulting in scarring and loss of exocrine tissues. Endocrine tissue is usually spared until late in the disease. Dilated ducts hold inspissated fluids. Calcification is also prevalent. 2 Small residual atrophic ducts in a fibrous background can mimic infiltrating pancreatic carcinoma. A new variant of chronic pancreatitis has been identified, characterized by a periductal and perivenular inflammatory cell infiltrate rich in IgG4+ plasma cells. Patients generally have elevated serum IgG4 levels. This variation is believed to be autoimmune in nature.
Prognosis: Alcoholic chronic pancreatitis is typically associated with poor outcomes.
Treatment is primarily supportive, and most patients will have other alcohol-related issues. • Steroid medication is effective in treating autoimmune pancreatitis, improving the outlook for patients.
