Introduction: raised diminutive colon lesions are of great interest due to their frequent appearance in endoscopic procedures and their association with adenomatous lesions. Objective: carry out a clinical, endoscopic and histological characterization of this type of lesions. Methods: an observational descriptive cross-sectional study was conducted at the Institute of Gastroenterology from January 2007 to June 2009. The sample consisted of 249 raised diminutive colon lesions found in 193 patients aged 18 and over. These patients underwent colonoscopy and biopsies were taken from their lesions. Results: there was a prevalence of the 50-69 age group, female sex and white skin color. Most patients were asymptomatic and the colon disease most commonly associated was polyps. The most common locations were the sigmoid colon and the rectum, with a prevalence of £ 2 mm and > 4-5 mm lesions. Most lesions were non-neoplastic and all adenomas were tubular. Low-grade dysplasia was the most common.
