Pilomyxoid astrocytoma

Angiocentricity, a hallmark of pilomyxoid astroctyoma, is demonstrated here
Although thought to be related to pilocytic astrocytoma, full characterization of pilomyxoid astrocytoma has yet to yield a definitive WHO grade for these tumors (although the prior edition of the WHO book pegged this tumor as grade II). Pilomyxoid astrocytomas differ from pilocytic astrocytomas in that they tend not to be biphasic or harbor Rosenthal fibers.

Thank you for your continued conversation regarding PMA. My child was diagnosed in 2014. I have some questions about the histology of PMA that was not available for discussion at the time of my experience. Are you available for offline discussion? Wondering if there is something that is common within all locations for this type of tumor that all literature is now mentioning over the years since my child was diagnosed.
