title: [Neoplastic polyps of the colon].
abstract: We report all patients with neoplastic polyps endoscopically excised during 10 years, performed in different hospitals in Mexico City. All ages, both sexes and socio-economic levels were seen in several endoscopy services both, public and private. We find 190 patients (100 females) with 268 polyps and a mean age of 54.5 (range 18-86). Tubulo-villous adenomas have the less frequency (8%). Villous adenomas were the largest and had a 11% frequency, almost all were confined to recto-sigmoid region its mean age was 6 years. Villous adenomas were the most frequent (69%) distributed in all colonic segments, its mean age was 54.5 years with the widest range (18-80 years); they have highest dysplasia rate (8.1%). Carcinomas arising in polyps were all located in recto-sigmoid region, with female predominance (2.3:1) and oldest mean age of presentation (66.3 years). Neoplastic polyps in Mexico City general population has a low frequency; endoscopic polypectomy is safe and had a low morbi-mortality rate.
