Background: Colonic polyp is a clinical definition that refers to lesions presenting a protrusion of the mucosa, without considering histology. The most recent classification by the WHO is based on a better understanding of these lesions; however, its application in daily practice may be subject to interobserver variability biases that could have clinical implications. Objectives: To determine interobserver variability in the histopathological reporting and grading of dysplasia in samples obtained from elevated colon lesions in a private laboratory in the city of Lima. Materials and Methods: Observational, descriptive, and prospective study: Case series type. All biopsies of elevated colon lesions received within a period of 03 months were evaluated by two observers without clinical information on the cases, to diagnose the lesions according to the WHO classification. In cases of diagnostic differences, the cases were evaluated together to reach a consensus. Results: A Kappa coefficient value of 0.458 was obtained in the diagnostic classification of elevated colon lesions, while a Kappa value of 0.416 in the evaluation of dysplasia, indicating moderate agreement. Conclusions: The study demonstrates that, despite achieving moderate agreement among evaluators, it emphasizes the importance of not relying solely on morphological criteria for diagnostic classification but also including criteria related to the location and size of these lesions to increase diagnostic accuracy.
