ES. a, b Loosely cohesive or tight clusters with perivascular arrangement of tumor cells and occasional rosette-like structures (H&E stain). c, d Dual appearances: small dark and large light cells, tigroid background, and intracytoplasmic vacuoles obvious in air-dried smears (MGG stain). e Cytoplasmic glycogen associated with cytoplasmic vacuoles and clear spaces (cell block; PAS stain). b, f Uncommon, divergent findings in smears: intranuclear inclusions and eosinophilic tissue fragments (desmoplasia) in the background of the smears (H&E and MGG stains).
