- 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.
