Cellular Classification of Colon Cancer

Histologic types of colon cancer include the following:

  • Adenocarcinoma (most colon cancers).
    • Mucinous (colloid) adenocarcinoma.
    • Signet ring adenocarcinoma.
  • Scirrhous tumors.
  • Neuroendocrine.[1] Tumors with neuroendocrine differentiation typically have a poorer prognosis than pure adenocarcinoma variants.
