Insights

This case highlights idiopathic duct-centric pancreatitis (IDCP) with granulocytic epithelial lesions (GEL) in Japan. It offers valuable insights into IDCP, distinct from typical autoimmune pancreatitis presentations.

Area of Science:

  • Gastroenterology
  • Pathology

Background:

  • Autoimmune pancreatitis (AIP) is a chronic inflammatory condition often presenting as lymphoplasmacytic sclerosing pancreatitis (LPSP).
  • Distinguishing between AIP subtypes is crucial for accurate diagnosis and treatment.

Observation:

  • A 65-year-old woman presented with elevated pancreatic enzymes and imaging findings suggestive of pancreatic malignancy.
  • Abdominal US, contrast-enhanced CT, MRCP, and ERCP revealed pancreatic body and tail swelling with abrupt main pancreatic duct (MPD) termination.

Findings:

  • Histopathological examination confirmed idiopathic duct-centric pancreatitis (IDCP) with granulocytic epithelial lesions (GEL).
  • This diagnosis contrasts with the more common LPSP subtype of AIP observed in Japan.

Implications:

  • This case expands the understanding of IDCP clinical manifestations in Japan.
  • Recognizing IDCP with GEL is important for differentiating it from other pancreatic diseases, including malignancy and typical AIP.

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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...

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...

Acute Pancreatitis I: Introduction01:25

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
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:
