Do all colorectal mucinous adenocarcinomas arise via the serrated neoplasia pathway?

The Journal of Pathology: Clinical Research, Volume 12, Issue 3, May 2026.
Abstract Colorectal mucinous adenocarcinomas (MACs) and serrated adenocarcinomas (SACs) demonstrate considerable overlap in morphological and molecular features, suggesting a spectrum rather than two distinct tumour types. This study investigates the presence of serrated morphological features, precursors, and molecular features in a large cohort of ...
