Oligodendrogliomas with abundant refractile eosinophilic granular cells.

چکیده
Refractile eosinophilic granular cells, when present in abundance in a glioma, may trigger a diagnosis of the relatively familiar and inherently malignant 'granular cell astrocytoma'. The following two cases remind us that refractile eosinophilic granular cells are not unique to granular cell astrocytoma but can also dominate the histology of oligodendroglioma confirmed by 1p19q loss, and the immunohistochemical and ultrastructural features of two such cases are reviewed. Refractile eosinophilic granular cells are not to be confused with the similar sounding term of eosinophilic granular bodies, the hyaline PAS positive a c c u m u l a t i o n s frequenting low grade glial and glioneuronal tumours.
