  • Uncommon, benign (WHO I) tumor that occurs in both children & adults.

Subtypes of craniopharyngioma

Adamantinomatous craniopharyngioma

  • epithelium that form stellate reticulum, wet keratin & basal palisades.
  • Up to 95% of this variant shows CTNNB1 mutations & aberrant nuclear expression of β-catenin.
  • Bimodal age distribution: childhood peak age 5–15 yrs, adult peak age 45–60 years.

Papillary craniopharyngioma

  • epithelium that form papillary features.
  • MC in supratentorial compartment or 3rd ventricle.
  • 81–95% of cases show BRAF V600E mutations.
  • Usually solid, or rarely cystic.
  • almost exclusively in adults w/ ~40–55 y/o.
