title: Colonic varices: a rare, but important cause of gastrointestinal hemorrhage.
abstract: The diagnosis of colonic varices, a rare cause of gastrointestinal hemorrhage, may be exceedingly difficult. If this entity is not considered, a rectal or colonic biopsy may lead to brisk and dangerous bleeding, as in our patient on two separate occasions. Once the diagnosis is made, appropriate surgery will prevent future bleeding episodes.
