Abstract:
Serrated polyps of the colorectum are a heterogeneous group of lesions with potential malignant transformation through the «serrated pathway» of carcinogenesis. The discovery of these lesions has been a paradigm shift in the concept of the adenoma-carcinoma sequence, so that up to 30% of tumors develop through this pathway. The main factors associated with an increased risk of malignancy in serrated polyps are size≥10mm, multiplicity, sessile serrated adenoma histology, presence of associated dysplasia and proximal location. Current evidence indicates that these lesions should be resected completely, and the patient requires an endoscopic surveillance program. Serrated polyposis syndrome is a clinicopathological entity characterized by multiple and/or large serrated polyps with an increased risk of developing colorectal cancer. These patients and their families, require multidisciplinary assessment in specialized high risk colorectal cancer units.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
