16 immunohistochemistry profiles of
PXA
, giant‐cell glioblastoma (
gcGBM
) and ganglioglioma (
GG
). Among PXAs, 51% of cases were both VE1‐immunopositive (+) and p16‐immunonegative (−). This combination was not observed among 28 giant‐cell glioblastomas, which were VE1‐negative in all cases and either p16‐negative or p16‐positive. Among gangliogliomas, combined VE1‐positive and p16‐negative results were observed in only 3/63 cases (5%), the majority being VE1‐positive and p16‐positive. Data on ganglioglioma from Koelsche et al
