Eosinophilia may be seen in all of the following conditions EXCEPT which one?

Eosinophilia, which refers to an elevated eosinophil count in the blood, is commonly associated with various medical conditions. In allergic reactions, eosinophils are often elevated as they play a role in the body's immune response to allergens, contributing to inflammation. Parasitic infections also typically trigger an increase in eosinophils, as these cells help combat parasitic infestations. Chronic myelogenous leukemia is a myeloproliferative disorder that can lead to increased numbers of eosinophils, especially during certain phases of the disease, although it primarily involves an increase in myeloid cells overall.

Erythroleukemia, on the other hand, is a type of acute leukemia characterized by an increase in immature red blood cell precursors and does not typically involve a significant elevation in eosinophils. This condition is more closely associated with dysplastic changes in erythroid cells rather than an eosinophilic response. Therefore, choosing erythroleukemia is accurate in this context, as it is not commonly linked to eosinophilia compared to the other conditions listed.
