Adenoma size and number are predictive of adenoma recurrence: implications for surveillance colonoscopy.

Background: Three-year colonoscopic surveillance after initial polypectomy may not be required for all patients. Those with multiple baseline polyps and large adenomas, implicated as predictors of colon cancer, merit close observation. Conversely, patients with single small adenomas may be subjected to early endoscopic surveillance unnecessarily.

An unusual cutaneous manifestation of ulcerative colitis: thrombotic skin gangrene.

Ulcerative colitis has a number of associated skin lesions. We report the case of a patient with active ulcerative disease presenting with rapidly progressive necrotic skin lesions, identified as thrombotic and requiring skin grafting. Thrombotic cutaneous gangrene is a rare but potentially serious manifestation of uncontrolled ulcerative colitis.
