Background The importance of identifying flat colorectal neoplasms is increasingly appreciated, although the extent of prevalence of these lesions in a general population is not known. Objective To determine the extent of prevalence of flat neoplasms in a diverse population undergoing routine endoscopic screening for colorectal cancer. Design Patients referred to the Colorectal Cancer Screening Clinic over a 12‐month period ( n = 642). Results The patient population was 56% African American and 21% Caucasian; with a mean age of 59 ± 9 years. Flat neoplasms were detected in 5.5% of all patients, similar to that reported elsewhere, with extent of prevalence being similar regardless of gender or race. Average size of flat neoplasms was of 2.8 ± 2.3 mm (range 1–20 mm). However, there was no evidence of advanced pathology in any of the flat neoplasms identified. Conclusions Flat neoplasms are common but may not be associated with advanced pathology in a population undergoing routine screening.
