A CLINICAL AND ULTRASTRUCTURAL STUDY OF ACUTE ESOINOPHILIC LEUKEMIA

The present study analyses two cases with acuteimmature eosinophilic leukemia. The clinical, physical,laboratory and pathologic materials are discussed.There is an abnormal number of immature eosinophiliccells in the blood and bone marrow, usually accompaniedby anemia and thrombocytopenia. Especially the ultra-structural features include abnormal granules, asyn-chronous maturation of the nucleus and cytoplasm,dilated endoplasmic reticulum and more Conspicuousnucleoli. Differential count was more precise underelectron microscope than under light microscope. Thesefindings may be helpful for differential diagnosis andclassification.
