9352/1 Craniopharyngioma, papillary


Definitions

Tumours of the central nervous system
ICD-O-3 topography code: C70, C71 and C72

A craniopharyngioma composed of sheets of squamous epithelium which separate to form pseudopapillae. This variant typically lacks nuclear palisading, wet keratin, calcification, and cholesterol deposits. Clinically, endocrine deficiencies are more often associated with papillary craniopharyngioma than with the adamantinomatous type. Papillary craniopharyngiomas occur almost exclusively in adults, at a mean age of 40?55 years 1
