[HTML][HTML] Clinicopathological features and global genomic copy number alterations of pilomyxoid astrocytoma in the hypothalamus/optic pathway: comparative analysis …
Pilomyxoid astrocytoma is a recently identified variant of pilocytic astrocytoma. We studied
11 circumscribed astrocytomas with focal (n= 5) or diffuse (n= 6) pilomyxoid features and
compared them with 17 pilocytic astrocytomas from the hypothalamic/chiasmatic region in
children. In one patient, a tumor that recurred after initial surgery had changed from pure-
form pilomyxoid astrocytoma to the mixed form. The presence of a pilomyxoid area was
associated with shorter survival. Next, we compared the comprehensive genome copy …
