Craniopharyngiomas are epithelial tumors that usually arise in the pituitary stalk adjacent to the optic chiasm. On gross pathology, craniopharyngiomas are cystic or partially cystic with solid areas.The cyst is filled with a turbid, proteinaceous material of brownish-yellow color that glitters and sparkles because of a high content of floating cholesterol crystals. On microscopic histopathology, it is categorized into two subtypes: Adamantinomatous and papillary.
