Lymphangioma of the large intestine is rare benign tumor which is composed of numerous small or large thin-walled lymphatic spaces contained fibrous tissue, smooth muscle and aggregastes of lymphoid tissue. Lymphangioma of the large intestine has
not
any pathognomic signs or sympthtoms, and never demonstrated any potential for malignant degeneration. There are three types: 1) simple capillary lymphangioma, 2) caveronous lymphangioma, and 3) cystic lymphangioma. Recently, We experienced a case
of
cystic lymphangioma of large intestine which has been revealed smooth surfaced, non lobulated, soft, polypoid mass with broad base in the transverse colon near the hepatic flexure by colonoscopy and cystic mass limited to the submucosal layer of
the
transverse colon by water-filled ultrasonogram, and confirmed by surgical resection.
