Serrated polyps with "intermediate features" of sessile serrated polyp and microvesicular hyperplastic polyp: a practical approach to the classification of nondysplastic serrated polyps.

Abstract excerpt

Sessile serrated polyps (SSPs) have been implicated in the pathogenesis of proximal colonic carcinomas, but they lack well-defined diagnostic criteria and their features overlap considerably with those of microvesicular hyperplastic polyps (MVHPs). We have noted that morphologic features of SSPs are often present in small, distally located MVHPs, suggesting that these polyps represent points on a continuum,...
