Lipoma of the colon.

Lipoma, an uncommon tumor in the gastrointestinal tract, occurs most often in the colon. The majority are asymptomatic but may cause abdominal pain, obstruction, or bleeding. The diagnosis can be made roentgenographically but is usually not made until operation is performed. Small lipomas may be removed by colonoscopy or followed conservatively after biopsy via colonoscopy. The treatment for symptomatic or large lipomas is surgical excision.
