WebBACKGROUND AND PURPOSE: Suprasellar papillary craniopharyngiomas and germ cell tumors in adults share some clinical and imaging similarities but have different therapeutic strategies and outcomes. Th WebMaterials and methods: b-Catenin, EGFR, ErbB2, and p63 immunostaining was performed on paraffin embedded tissue sections of 25 CPs including 18 adamantinomatous craniopharyngioma (ACP) and 7 cases of papillary craniopharyngiomas (PCPs). Results: 17 cases (94%) of ACP exhibited strong nuclear/cytoplasmic expression of b-catenin.
