title: Lymphangioma of the transverse colon treated by transendoscopic polypectomy: report of a case and review of literature.
abstract: This report concerns a 73-year-old man complaining of intermittent, dull, umbilical pain on one month's duration. Barium-enema examination and endoscopy revealed a hemispheric cystic tumor at the midportion of the transverse colon, and the presumptive diagnosis was cystic submucosal tumor of the colon. Transendoscopic polypectomy was performed and the bulk of the lesion was locally excised from the colonic mucosa. Histologic examination revealed cavernous lymphangioma originating from the submucosa.
