Abstract:
Autoimmune pancreatitis is a rare cause of chronic pancreatitis and pancreatic mass. We describe a case of focal autoimmune pancreatitis in a 51-year-old man presenting with obstructive jaundice and pancreatic mass, mimicking malignancy. The immunological test was suggestive of autoimmune pancreatitis, and the patient responded well to a course of steroids, with complete resolution of the pancreatic mass. Autoimmune pancreatitis, therefore, must be kept in mind as a differential diagnosis of pancreatic mass. Recognition of this disease by its typical radiological and serological findings may help to avoid unnecessary surgical resection.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
