Monstrocellular Glioblastoma wit

Monstrocellular glioblastoma, also called giant cell glioblastoma. The hallmark of this subtype of GBM is the presence of enormous mononucleated and multinucleated tumor cells, as indicated by the unnecessarily large green arrow. Much of the proliferation of this type of tumor occurs with the intervening smaller tumor cells. Like other GBMs, this is a WHO Grade IV tumor.
