RESUMEN
The problem of single adenomatous polypus and adenocarcinoma of rectosigmoid is debatable. Forty eight polypi with adenomatous structure were diagnosed and total polypectomy performed with 925 rectoromanoscopic examinations. In 6 of them, zones of malignization various in dissemination, were histologically confirmed. In two of the patients intestinal resection was performed, due to invasion of the malignization within the base of the polypus. The rest, four patients, with focal superficial malignization and the other 42 patients with "pure" adenomatous polypi are subjected to periodical rectoromanoscopic observations.
