Myeloid neoplasms with PDGFRB usually present as chronic myelomonocytic leukemia, but may also present as atypical chronic myeloid leukemia (aCML), CEL, MPN with eosinophilia, AML and juvenile myelomonocytic leukemia (JMML). [neogenomics.com]

Here, we discuss the case of 51 year old man who presented with nodal myeloid sarcoma mimicking lymphoma as the presenting feature of his FIP1L1 - PDGFRA myeloid neoplasm. [jscimedcentral.com]

In patients who present with CEL there may be subsequent transformation to AML, T or B lymphoblastic leukaemia or MPAL. [viapath.co.uk]

Core-binding factor AML with inv(16) or t(16;16) can also present with eosinophilia, may present with less than 20% blasts, and still meet criteria for AML if the chromosomal 16 abnormality is present. [clinicaladvisor.com]

A minority of patients present with acute leukemia, either myeloid or T-lymphoblastic with preceding eosinophilia being documented or being present at the time of diagnosis. 5 The prototype of this group of neoplasms is CEL associated with a FIP1L1-PDGFRA [clinicalgate.com]

• Vascular Disease

  diseases Kimura disease Vasculitis Cyclical eosinophilia Aberrant T cell population associated eosinophilia Also known as lymphocyte variant hypereosinophilia Abnormal T cell population does not meet diagnostic criteria for leukemia or lymphoma Causes [surgpathcriteria.stanford.edu]

• Hypercellular Bone Marrow

  Most of the patients show a hypercellular bone marrow that leads to a diagnosis of myeloid hyperplasia or a myeloproliferative neoplasm. [atlasgeneticsoncology.org]

At initial diagnosis or before treatment the RUNX1 mutations were subclonal. [ncbi.nlm.nih.gov]

BCR/ABL1 tyrosine kinase inhibitors (TKIs ) have been developed as a first line treatment for patients with CML. These include Imatinab and Desatinab but there are also other treatments. [viapath.co.uk]

• Oral once daily dosing: 21-day (2-weeks-on/1-week-off) cycle Start disease assessment* after cycle 2 • Stable disease/partial or complete response → continue treatment on 21-day cycle • Disease progression → discontinue treatment; safety and survival [cancerres.aacrjournals.org]

This form of myeloid sarcoma is distinguished by its highly successful treatment with imatinib (the recommended treatment for FIP1L1-PDGRGA fusion gene-induced eosinophilic leukemia) rather than more aggressive and toxic therapy. [5] Primary chloroma [en.wikipedia.org]

Imatinib mesylate (imatinib) is the first-line therapy for patients with abnormalities of PDGFRA/B, whereas patients with FGFR1 fusions are resistant to this therapy and carry a poor prognosis. [ncbi.nlm.nih.gov]

[…] definition to require biallelic mutations. • A provisional category of AML with mutated RUNX1 has been added to the classification for cases of de novo AML with this mutation which has possibly worse prognosis than other AML types. 39. [slideshare.net]

Disease prognosis relies on accurately classifying the eosinophilia. [eposters.net]

Diagnostic criteria for polycythemia vera (PV) are notably changed to lower the hemoglobin threshold and thus prevent underdiagnosis. [hematology.org]
