AbstractOptical diagnosis during colorectal cancer screening is instrumental in deciding whether or not to resect colorectal lesions, choose the appropriate technique and to properly communicate with the pathologist. The latter is even more important when it comes to serrated lesions with the latest WHO classification justifying a pathology diagnosis of a serrated lesion with a minimum criterion of characteristic findings in just one crypt, which may only be detectable when adequate sectioning and scrutinization is performed. Here, we present a unique case of comparatively small rectal lesions with typical endoscopic findings warranting a diagnosis of a serrated lesion (open pit pattern) and adenoma (valley sign).
Rectal polyp and hemorrhoids are common causes of bleeding per rectum in pediatric age group.However, there are some other causes which should be considered in differential diagnosis. We haveacquainted a case of rectal bleeding due to solitary rectal ulcer in a child of 10 year. Colonoscopicexamination was required for diagnosis as proctoscopic examination and digital rectal examinationmissed the diagnosis, probably due to poor co-operation by the patient and rare nature of the disease.Although well recognized in the adult population, the pediatric experience with this condition islimited.Key word: children, rectal bleeding, solitary rectal ulcer
