There are few studies from Iran regarding to the predominant type of polyps in colorectal area. Objectives We conducted this retrospective study to evaluate the predominant colorectal polyps in our center as the largest referral center of the South region of Iran. Material and Methods We retrospectively analyzed pathology reports of colonoscopies during five years (2005 - 2011). Histologic reports and demographic findings were recorded and compared with published studies in the literatures of other countries from different geographic regions of the world. Results During these years, 990 patients with colorectal polyps were refered to the center. The most common types of polyps were adenomatous (603), followed by hyperplastic (300), juvenile (80), inflammatory (5) and Peutz-Jeghers (2). The most common site of polyp was rectosigmoid. Discussion The type and distribution of colorectal polyps in Iran is very similar to western countries.
