Epithelial colon polyps are largely divided into hyperplastic and adenomatous polyps. Adenomatous polyps are premalignant lesions, whereas hyperplastic polyps are regarded as benign lesions. However, this histological classification has been blurred, as cases of malignant changes in hyperplastic polyposis, mixed hyperplastic adenomatous polyps (MHAPs), and serrated adenomas in the colon have been reported. Rare cases of MHAP have been reported, and are mainly found at the proximal colon with a relatively large size. MHAPs seem to be an intermediate stage of the hyperplastic polyp-adenoma sequence or a collision tumor. Here, we report on a case of a single polyp in the rectum diagnosed with a MHAP combined with an invasive adenocarcinoma. (Intest Res 2012;10:295-299)

Klippel - Trenaunay syndrome (KTS) is characterized by a cutaneous vascular nevus of the involved extremity, bone and soft tissue hypertrophy of the extremity and venous malformations. We present a case of KTS with splenic hemangiomas and rectal varices. A 29-year-old woman was referred for intermittent hematochezia for several years. She had history with a number of operations for cutaneous and soft tissue hamangiomas since the age of one year old and for increased circumference of her left thigh during the last few months. Abdominal CT revealed multiple hemangiomas in the spleen, fusiform aneurismal dilatation of the deep veins and soft tissue hemangiomas. There was no evidence of hepatosplenomegaly or liver cirrhosis. Colonoscopy revealed hemangiomatous involvement in the rectum. There were rectal varices without evidence of active bleeding. Upon venography of the left leg, we also found infiltrative dilated superficial veins in the subcutaneous tissue and aneurismal dilatation of the deep veins. The patient was finally diagnosed with KTS, and treated with oral iron supplementation only, which has been tolerable to date. Intervention or surgery is not required. When gastrointestinal varices or hemangiomatous mucosal changes are detected in a young patient without definite underlying cause, KTS should be considered. (Korean J Gastroenterol 2011;58:157-161)
