Myeloid Neoplasms with t(5;12) and ETV6-ACSL6 Gene Fusion, Potential Mimickers of Myeloid Neoplasm with PDGFRB Rearrangement: Case Report with Imatinib Therapy and Review of the Literature
We report the second case of ETV6-ACSL6 associated myeloproliferative neoplasm that has received a full course of imatinib therapy. The patient was a 51-year-old previously healthy man who presented with three months of worsening dyspnea and was found to have a white count of 216,000/cmm, of which 84% were eosinophil lineage. Cytogenetic analysis revealed a t(5;12)(q31~33;p13). FISH was negativ...
متن کاملHyper eosinophilia associated with myeloid and lymphoid neoplasms
Eosinophilia in the absence of allergies, asthma, drug reactions, parasitic infections and connective tissue diseases can be eosinophilic clonal disorders, lymphoma or myeloproliferative disorders. Hypereosinophilia with the persistence of eosinophils ≥1500 /mm³ in blood or more than 20% of eosinophils in the bone marrow may be observed in many reactive or clonal disorders, the result of which ...
متن کاملETV6 mutation in a cohort of 970 patients with hematologic malignancies.
The ETV6 gene (previously known as TEL) belongs to the ETS (E26 transformation specific) family of transcription factors characterized by 2 important domains: the Cterminal Ets domain responsible for specific DNA-binding activities and the N-terminal helix–loop–helix (HLH) oligomerization domain, also known as pointed (PNT) or sterile alpha motif (SAM), that mediates protein–protein interaction...
متن کامل[Myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1].
The 2008 World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues introduced a new category for myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1. Many of these cases present as a myeloproliferative neoplasm, usually with eosinophilia. However, neoplasms associated with rearrangement of PDGFRA can present as acute...
متن کاملPDGFRB-rearranged T-lymphoblastic leukemia/lymphoma occurring with myeloid neoplasms: the missing link supporting a stem cell origin.
The 2008 WHO classification scheme of hematolymphoid neoplasms recognizes a category of myeloid and lymphoid neoplasms (MLNs) with eosinophilia and abnormalities of PDGFRA, PDGFRB, or FGFR1. The postulated cell of origin for PDGFRA or FGFR1-rearranged diseases is a pluripotent progenitor capable of giving rise to myeloid neoplasms (myeloproliferative neoplasms and acute leukemias) and to lympho...
