A 56-year-old woman with liver cirrhosis complained of tarry stool. She was admitted to our hospital for further examination. On upper endoscopic examination no esophageal or gastric varices and no ulceration were seen. There were no abnormal findings at X-ray series and endoscopy of small intestine. Barium enema showed round filling defect with slight irregularity, about 3cm of size located at the ascending colon. Colonoscopic exami-nation revealed submucosal lesion which color appeared slightly pale. Varices were suspected in addition to submucosal tumor. Color doppler ultrasonography and abdominal angiography demonstrated a enormous collateral vessel between superior mesenteric vein and inferior vena cava in right flank abdomen. Endoscopic ultrasonography revealed a luminal structure in the wall. corresponding to the elevated lesion, and we diagnosed colonic varices. Colonic varices are rare, but when patients with portal hypertension are examined, colonic varices must be took into account.
