Notes: Non-malignant CNS, January 2019 Update
Update to current manual/Solid Tumor Rules (2018)/Histology--Brain and CNS: Table 6 (Non-Malignant CNS Equivalent Terms and Definitions) lists
Adenomatous craniopharyngioma 9351/1 as a subtype/variant of craniopharyngioma 9350/1. This is not a valid histology per the ICD-O-3 or the 2018 ICD-O-3 Update Table. Is this actually supposed to read,
Adamantinomatous craniopharyngioma 9351/1?
Adamantinomatous craniopharyngioma (9351/1) is a subtype of craniopharygioma. We will correct the Non-Malignant CNS Solid Tumor Rules in the next update.
