Lynch syndrome (LS) is the most common cause of inherited colorectal cancer and the increases risk of developing extracolonic cancers. We present the first case of pediatric-onset LS with recurrent adenomatous colonic polyps presenting with rectal prolapse. This case highlights the importance of considering polyposis syndromes such as LS as possible diagnoses for pediatric patients who present with colorectal adenomatous polyps, as well as the need to consider immunohistochemical staining of polyps for mismatch repair protein expression in pediatric populations to rule out LS as a diagnosis. We demonstrate the need to consider pediatric patients in LS guidelines.
