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 ...
Eosinophilia is a condition in which the eosinophil count in the peripheral blood exceeds 5 × 10 8 /L (500/μL). [1] Hypereosinophilia is an elevation in an individual's circulating blood eosinophil count above 1.5 × 10 9 /L (i.e. 1,500/μL).
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
Hypereosinophilia (i.e. blood eosinophil counts at or above 1,500 per microliter) or, less commonly, eosinophilia (counts above 500 but below 1,500 per microliter) are found in the vast majority of cases of eosinophilic myocarditis and are valuable clues that point to this rather than other types of myocarditis or myocardial injuries. However ...
Hypereosinophilia, extreme increase (>1,500 cells per microliter) in eosinophil blood count; Clonal hypereosinophilia, presence of a premalignant or malignant clone of eosinophils in bone marrow and blood; Chronic eosinophilic leukemia; Acidophile (histology) List of distinct cell types in the adult human body
Clonal hypereosinophilia, also termed primary hypereosinophilia or clonal eosinophilia, is a grouping of hematological disorders all of which are characterized by the development and growth of a pre-malignant or malignant population of eosinophils, a type of white blood cell that occupies the bone marrow, blood, and other tissues.
Lymphocyte-variant hypereosinophilia is a rare disorder in which eosinophilia or hypereosinophilia (i.e. a large or extremely large increase in the number of eosinophils in the blood circulation) is caused by an aberrant population of lymphocytes.
Familial eosinophilia is a rare congenital disorder characterized by the presence of sustained elevations in blood eosinophil levels that reach ranges diagnostic of eosinophilia (i.e. 500–1500/microliter) or, far more commonly, hypereosinophilia (i.e. >1,500/microliter).
