Abstract
Lymphangioma occurring in the large intestine is a rare benign tumor. We have recently encountered a case of lymphangioma of the ascending colon. The patient was a 42-year-old male who was admitted to our hospital for the treatment of cholecystolithiasis.
Colonoscopic examination, performed incidentally, revealed about 20mm in size, semilimpid globular submucosal tumor with “cushion sign” in the ascending colon.
Barium enema examination demonstrated a sharply marginated round defect with increased radiolucency in the same site.
These findings were suggestive for colonic lymphangioma.
Initially, polypectomy under endoscopic control was thought to be feasible, however, surgical resection was adopted because he was expecting laparotomy for cholecystolithiasis, Histopathologically, the colonic lesion was diagnosed as cystic lymphangioma. In this paper, we have discussed efficiency and usefulness of total colonoscopy on diagnosis and treatment of colorectal lymphangioma.
