Experimental Factor Ontology term EFO_1000447 (Papillary Craniopharyngioma) is 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. (Adapted from WHO).
