Focal nodular hyperplasia (FNH), a benign liver tumor, can rarely rupture and bleed, mimicking surgical emergencies. This case underscores the risk, even in asymptomatic FNH, especially with larger lesions.
Area of Science:
- Hepatology
- Surgical Pathology
Background:
- Focal nodular hyperplasia (FNH) is a common benign liver lesion.
- Typically asymptomatic, FNH rarely requires intervention when diagnosed non-invasively.
Observation:
- A 42-year-old woman presented with an acute surgical abdomen due to a ruptured and hemorrhagic FNH.
- The diagnosis was confirmed post-surgical resection and histopathological examination.
Findings:
- Hemorrhage and rupture of hepatic FNH are extremely rare complications.
- Large FNH lesions may carry a small but significant risk of rupture.
Implications:
- This case highlights the importance of considering rare complications of FNH.
- Even benign liver tumors like FNH can present as surgical emergencies, necessitating prompt diagnosis and management.

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:

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...
