What about this cell with red granular cytoplasm?

I'm working on a high-grade glioma and am coming across scattered presumably neoplastic cells that have course red granular cytoplasm. How does one interpret such cells? Does it raise the possibility of a granular cell astrocytoma? Or are these often present and I've just ignored them until now? Thanks for any help you might be able to provide in the comments section!
