Based on their causes, hypereosinophilias can be sorted into subtypes. However, cases of eosinophilia, which exhibit eosinophil counts between 500 and 1,500/μL, may fit the clinical criteria for, and thus be regarded as falling into, one of these hypereosinophilia categories: the cutoff of 1,500/μL between hypereosinophilia and eosinophilia is somewhat arbitrary.
Depending on eosinophil target-organ infiltration, the clinical presentation of hypereosinophilic syndrome (HES) varies from patient to patient. [13] Individuals with myeloproliferative variant HES may be more likely to experience mucosal ulcerations involving the genitalia or airways, while patients with lymphocytic variant HES typically exhibit prominent skin symptoms such as urticarial ...
For instance, patients with eosinophilic asthma have high levels of eosinophils that lead to inflammation and tissue damage, making it more difficult for patients to breathe. [ 6 ] [ 7 ] Eosinophils persist in the circulation for 8–12 hours, and can survive in tissue for an additional 8–12 days in the absence of stimulation. [ 8 ]
When overproduced and over-activated, such as in cases of eosinophilic myocarditis, eosinophils behave as though they were attacking a foreign or malignant tissue: they enter a seemingly normal organ such as the heart, misdirect their reactive oxygen species and armamentarium of preformed molecules toward seemingly normal tissue such as heart ...

In 10% to 25% of patients, mostly 3 to 10 years after initial diagnosis, the indolent course of lymphocyte-variant hypereosinophilia changes. Patients exhibit rapid increases in lymphadenopathy , spleen size , and blood cell numbers, some cells of which take on the appearance of immature and/or malignant cells.
