Large Intestine: Neoplastic Patterns and Mimics
Tumours and polypoid lesions of the colon are the most commonly encountered biopies in gastrointestinal practice. In this chapter, the entities are presented according to the schema outlined in chapter 1. Particular attention is paid to serrated lesions in the colon which is an area where our understanding of the morphological classification and pathogenesis of the lesions has expanded recently. Special attention is also given to inflammatory bowel disease related dysplastic lesions and to mesenchymal lesions of the colon, many of which almost exclusively occur at this site.
