ABSTRACT

Sessile serrated adenomas (SSA) were originally thought to be rare lesions, but recent literature suggests they may account for 3% to 9% of all colorectal polyps. Morphologically, these lesions are typically flat and Paris classification 0-IIa. The classic location of SSA is within the right colon. Here, we present a SSA which was pedunculated, Paris classification 0-Ip, and obtained from the sigmoid colon. To our knowledge, this represents a rare presentation of SSA with a limited number of previous cases. This observation should be considered by endoscopists when encountering similar lesions given the malignant potential of these polyps.
