Traditional serrated adenomas: what the endoscopist should  know

Hyperplastic polyps, once thought to have a benign course, are now part of a larger heterogeneous group known as serrated polyps, which include hyperplastic polyps (HPs), sessile serrated polyps (SSPs), and traditional serrated adenomas (TSAs). The latter group, once known as serrated adenomas, are relatively rare, accounting for less than 5% of all serrated polyps. Thus, it is not surprising that less is known about these lesions than about conventional adenomas or even SSPs. Because these lesions have dysplasia and can progress to colorectal cancer (CRC), more data regarding prevalence and risk factors TSAs are vital.
