Ewing sarcoma is a small-blue-round-cell tumor that typically has a clear cytoplasm on H&E staining, due to glycogen. The presence of the glycogen can be ...

Ewing's sarcoma is a very rare tumor which has, however, attracted much oncological interest since the dramatic improvement of its prognosis under ...

Ewing's sarcoma/PNET is a prototype of the “small round cell” tumor group. It is composed of sheets of small cells with high nuclear to cytoplasmic ratio. The cytoplasm is scant, eosinophilic, and usually contains glycogen, which is detected by periodic acid Schiff stain and is diastase degradable.
