morphology of UC vs. Crohn’s Disease
UC - pseudopolyps - ulceration and raised mucosa *Mucosa and Submucosa involved Crohn’s Disease - cobblestoning = walls are thick
Erythema Nodosum
painful red nodules, mosquto bites Parallels Bowel disease
Pyoderma gangrenosum
ulceration and skin necrosis Independent from bowel disease
Uveitis

PSC
Primary Sclerosis Cholngitis bile duct is narrowed - can process to cirrhosis and increased risk of cancer *Ulcerative Colitis
