Microscopic
Features:[1]
- Pineocytomatous/neurocytic rosette = irregular rosette with a large meshwork of fibers (neuropil) at the centre.[2]
- Similar to Homer-Wright rosette.
- Perinuclear clearing.
- Well-defined cell borders.
DDx:
- Oligodendroglioma - do not have the characteristic rosettes.
- Ganglioglioma.
- Ependymoma.
