Submucosal hematoma of the gastrointestinal tract can be formed during endoscopic examination. Two cases of colonic submucosal hematoma formed in the sigmoid colon resembling varices, were reported. We speculated that colonic submucosal hematoma could be formed when a stiffening cuff was intubated violently or a colonoscope was manipulated roughly. When mucosal separation between the superficial and deeper layers occurred, submucosal hematoma would be possibly formed. Though most cases of colonic submucosal hematoma are thought to heal spontaneously without any clinical troubles, there may be the possibility of massive bleeding from the hematoma. One should be always careful to do colonoscopic examination.
