Question:

Histology/Behavior--Brain and CNS: How should Histology and Behavior be coded for a polymorphous low-grade neuroepithelial tumor of the young (PLNTY) arising in the brain?

Discussion:

Answer:

Assign code 9505/1 for ganglioglioma. Per our expert neuropathologist, according to the paper that has done the most work on PLNTY cases, it appears most closely related to the ganglioglioma. It is surely a neoplasm as it has recurrent mutations and fusions seen in other tumors, again, most like gangliogliomas.
