Histologic types of rectal cancer include:

  • Adenocarcinoma (most rectal cases).
    • Mucinous (colloid) adenocarcinoma.
    • Signet ring adenocarcinoma.
  • Scirrhous tumors.
  • Neuroendocrine:[1] Tumors with neuroendocrine differentiation typically have a poorer prognosis than pure adenocarcinoma variants.
  • Carcinoid tumors. (Refer to the PDQ summary on Gastrointestinal Carcinoid Tumor Treatment 1 for more information.)
