A 25 year old woman presents with bloody diarrhea and is diagnosed as a case of Ulcerative colitis. Which of the following condition is not associated with ulcerative colitis?
**Core Concept**
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by inflammation and ulcers in the colon, leading to symptoms such as bloody diarrhea. The exact cause of UC is unknown, but it is believed to involve an abnormal immune response to gut bacteria, leading to chronic inflammation.
**Why the Correct Answer is Right**
Ulcerative colitis is associated with an increased risk of various extraintestinal manifestations, including arthritis, skin rashes, and eye inflammation. The condition is also linked to an increased risk of primary sclerosing cholangitis (PSC), a chronic liver disease characterized by inflammation and scarring of the bile ducts. Additionally, UC is associated with an increased risk of osteoporosis, particularly in patients taking long-term corticosteroids.
**Why Each Wrong Option is Incorrect**
**Option A:** Primary sclerosing cholangitis (PSC) is associated with ulcerative colitis, as mentioned earlier.
**Option B:** Osteoporosis is indeed a complication of ulcerative colitis, particularly in patients on long-term corticosteroids.
**Option C:** Ulcerative colitis is associated with an increased risk of colorectal cancer, particularly in patients with extensive disease or long-standing disease.
**Clinical Pearl / High-Yield Fact**
It is essential to screen patients with ulcerative colitis for extraintestinal manifestations, such as primary sclerosing cholangitis and osteoporosis, and to monitor them regularly for signs of these complications. Regular colonoscopy is also crucial to detect dysplasia and colorectal cancer.
**Correct Answer:** D
