| Field: | Gastroenterology |
| Symptoms: | Asymptomatic |
| Complications: | Colorectal cancer |

| Diagnosis: | Colonoscopy |
| Treatment: | Polypectomy |
| Frequency: | <1% of all colon polyps |
Traditional serrated adenoma is a premalignant type of polyp found in the colon, often in the distal colon (sigmoid, rectum). Traditional serrated adenomas are a type of serrated polyp, and may occur sporadically or as a part of serrated polyposis syndrome. Traditional serrated adenomas are relatively rare, accounting for less than 1% of all colon polyps.[1] Usually, traditional serrated adenomas are found in the distal colon and are usually less than 10 mm in size. __TOC__
Traditional serrated adenomas are characterized by ectopic crypts, pseudostratification, and a villous pattern with stretched nuclei.
Usually found in individuals over the age of 50 years, traditional serrated adenomas affect men and women equally.[2] The overall prevalence of traditional serrated adenomas is less than 1% of the general population.[3] Traditional serrated adenomas are the least common type of serrated polyps found in the colon, accounting for 5% of serrated colon polyps.[4]
