Pathology and Pathogenesis of Diverticular Disease and Patterns of Colonic Mucosal Changes Overlying the Diverticula

We were the first group to propose a histological classification for sigmoid colitis-associated diverticular disease, and in this paper we are adding another feature to our original observation.
