Rosenthal fibers.
H&E staining showing these elongated eosinophilic structures in a case of pilocytic astrocytoma. Magnification 400x
A Rosenthal fiber is a thick, elongated, worm-like or "corkscrew" eosinophilic (pink) bundle that is found on H&E staining of the brain in the presence of long standing gliosis, occasional tumors, and some metabolic disorders.

Associated conditions[edit]
Its presence is associated with either pilocytic astrocytoma[1] (more common) or Alexander's disease (a rare leukodystrophy). They are also seen in the context of fucosidosis.
Composition[edit]
The fibers are found in astrocytic processes and are thought to be clumped intermediate filament proteins.
Their components include glial fibrillary acidic protein.[2]
