Intramucosal colorectal carcinoma is a confusing term for high grade (colorectal) dysplasia that should be avoided.[1]

Intramucosal rectal carcinoma, intramucosal colonic carcinoma, intramucosal colonic adenocarcinoma, intramucosal rectal adenocarcinoma and colorectal adenocarcinoma in situ redirect here.

Background

  • Colorectal adenocarcinoma is defined by invasion into the submucosa.
    • This is different than elsewhere in the GI tract, where cancer is defined by invasion through the basement membrane, i.e. into the lamina propria.
    • Rationale: atypical (cancer-like) cells in lamina propria do not have metastatic potential as there are no lymphatics in the colorectal lamina propria.[2]
