[Lipoma of the colon]

Two cases of submucosal lipoma of the transverse colon are described with their anatomoclinic characteristics and the different aspects of their treatment. These lesions occur with the maximum frequency in the fifth or sixth decades of life and are mostly found in women. 18 per cent of them are located on the transverse colon. In 10 per cent of the cases, the lipomas are multiple. Their clinical symptoms are directly related to their size. Abdominal pains, rectal bleedings and signs of obstruction are the most common symptoms. Thanks to barium enema and endoscopic examination, they are usually diagnosed preoparatively and may be excised through a colotomy in the majority of cases, or by endoscopic removal.
