**Core Concept**
Primary sclerosing cholangitis (PSC) is a chronic liver disease characterized by inflammation and fibrosis of the intrahepatic and extrahepatic bile ducts, leading to bile duct strictures and eventual liver damage. This condition often presents with symptoms such as jaundice, pruritus, and abdominal pain, and is commonly associated with inflammatory bowel disease (IBD).

**Why the Correct Answer is Right**
PSC is a chronic and progressive disease, often requiring long-term management and potentially leading to liver transplantation. The exact pathogenesis of PSC is not fully understood, but it is believed to involve a combination of genetic predisposition, immune system dysfunction, and environmental factors. The disease is characterized by the presence of fibro-obliterative cholangitis, which involves the destruction of the bile duct epithelium and subsequent scarring of the bile ducts.

**Clinical Pearl / High-Yield Fact**
PSC has a strong association with IBD, particularly ulcerative colitis (UC), with approximately 70-80% of patients with PSC also having UC. This association highlights the importance of a thorough gastrointestinal evaluation in patients with PSC.
