Chronic eosinophilic leukemia is a form of cancer in which too many eosinophils are found in the bone marrow, blood, and other tissues. Most cases are associated with fusion genes . [ 1 ]
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 ...
Lymphoid neoplasms can be associated with eosinophilia presumably because of the secretion of eosinophil/eosinophil precursor cell-stimulating cytokines by the malignant lymphoid cells. Most commonly, this is seen in cutaneous T cell lymphoma , adult T-cell leukemia/lymphoma , and angioimmunoblastic T cell lymphoma .
It can arise de novo or may develop in patients having the chronic form of a hypereosinophilic syndrome. Patients with acute eosinophilic leukemia have a propensity for developing bronchospasm as well as symptoms of the acute coronary syndrome and/or heart failure due to eosinophilic myocarditis and eosinophil-based endomyocardial fibrosis.
The expanding population of eosinophils initially formed in the bone marrow may spread to the blood and then enter into and injure various tissues and organs. [1] Clinically, clonal eosinophilia resembles various types of chronic or acute leukemias, lymphomas, or myeloproliferative hematological malignancies. However, many of the clonal ...
When a pathologist examines a biopsy of a suspected cancer, they will stain the biopsy with H&E. Some structures seen inside cells are described as being eosinophilic; for example, Lewy and Mallory bodies. [4] Some cells are also described as eosinophilic, such as Leukocytes. [5]
If the cause is unknown, it is specified and called "simple pulmonary eosinophilia". Cardiac damage caused by the damaging effects of eosinophil granule proteins (e.g. major basic protein) is known as Loeffler endocarditis and can be caused by idiopathic eosinophilia or eosinophilia in response to parasitic infection.
