eosinophilic nonallergic rhinitis

Most characteristic is the presence of Curschmann's spirals, Charcot-Leyden crystals, and eosinophilic leukocytes.

Certain structures take up only acid dyes, and are called acidophilic, oxyphilic, or eosinophilic.

Nuclei, basophilic granules, and all blood parasites are blue; erythrocytes are red or pink; eosinophilic granules, bright red.

Myelocytes are named according to the character of their granules—neutrophilic, eosinophilic, and basophilic myelocytes.
