Resumen

HERREROS-DE-TEJADA, Alberto; GONZALEZ-LOIS, Carmen  y  SANTIAGO, José. Serrated lesions and serrated polyposis syndrome. Rev. esp. enferm. dig. [online]. 2017, vol.109, n.7, pp.516-526. ISSN 1130-0108.  http://dx.doi.org/10.17235/reed.2017.4065/2015.

The serrated pathway has been shown to be an alternative colorectal carcinogenetic route potentially accounting for up to one third of all CRCs. Serrated lesions, particularly SSPs, have been a focus of research during the past few years. They have well-established histological and molecular characteristics that account for their potential carcinogenetic risk through the accumulation BRAF, KRAS and methylator profile (CpG) mutations. Their endoscopic identification and resection represent a challenge because of their specific characteristics, and the need for an adequate specimen for histological diagnosis. Knowledge of these lesions is key, as is the adoption of established criteria for their endoscopic description and histological diagnosis. SPS is the maximum expression of involvement by serrated lesions, is associated with increased risk for CRC, and requires attentive endoscopic follow-up, as well as family screening. While the exact etiopathogenic mechanism remains unknown, current research will likely provide us with appropriate answers in the not too distant future.
