BRAF and adenocarcinoma: The serrated pathway adenocarcinomas of the proximal colon that do not display the morphological features of this pattern are more frequent CK7+/p53−/MLH-1−/BRAF-mutated/K-ras-wt/MSI cases, but those located in the distal colorectal segments seem to be CK7+/CK20+/p53−/MLH-1+/BRAF wt/K-ras-mutated/MSS cases.
