[Cystic lymphangioma of the colon: endoscopic treatment and diagnosis]

We present a case of cavernomatous cystic lymphangioma in the hepatic angle of the colon, a extremely rare benign tumor developed in a patient under continued radiologic and endoscopic surveillance because of multiple polyps and colon carcinoma. The lesion was asymptomatic and was diagnosed in a routine follow-up colonoscopy. The endoscopic appearance was similar to that of an adenomatous polyp and was safely resected by polypectomy without evidence of relapse to the present time. Trends in the treatment of lymphangioma have been changing since the development of snare polypectomy; thus before 1980 it was treated mainly by surgery, while at present lymphangiomas less than 2 cm have been removed more frequently by polypectomy.
