Initial cytogenetic analysis revealed a t(5;12)(q31~33;p13) in 17 of 20 cells (Figure 1(c)) and a presumptive diagnosis of myeloid neoplasm with eosinophilia and translocation t(5;12) suggestive of PDGFRB rearrangement was made.

Myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB, orFGFR1.
14) The major disease entities within this category are myeloproliferative neoplasm (MPN) with PDGFRA rearrangement, MPN with PDGFRB rearrangement, and the so-called 8p11 myeloproliferative syndrome.
Se incluyeron los pacientes mayores de 18 anos con los siguientes tipos de neoplasias mieloproliferativas: policitemia Vera, trombocitemia esencial, mielofibrosis idiopatica, leucemia eosinofilica cronica, neoplasia mieloproliferativa asociadas a eosinofilia (con rearreglo PDGFRA, PDGFRB y FGFR1) y neoplasias mieloproliferativas no clasificables.
Since PDGFRB and B-RAF work cooperatively, keeping both turned off causes synergistic effects in tumours, according to Cheresh.
In the 2008 World Health Organization classification system, the category of MPNs includes chronic myelogenous leukemia; chronic neutrophilic leukemia; polycythemia vera; primary myelofibrosis; essential thrombocythemia; chronic eosinophilic leukemia; mastocytosis; and MPN, unclassifiable; and the clinical and pathologic findings may overlap with the category of myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB, and FGFR1.
In a phase II open-label trial--Study B2225, the largest study involving patients with DFSP)--imatinib mesylate, an inhibitor of PDGFRB, was found to be safe and effective in the treatment of patients with locally advanced and metastatic DFSP tumors containing t(17;22) translocation.
Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed to detect gene rearrangements of BCR / ABL , FIPIL1/PDGFRA , TEL / PDGFRB were all negative as well as c-KIT and JAK2V617F mutations.
Crenolanib is a selective inhibitor of PDGFRA and PDGFRB that has been reported to inhibit the PDGFRA D842V mutant kinase and to be 100- to 150-fold more potent than imatinib against that mutation.
These neoplasms respond to tyrosine kinase inhibitors and are addressed below in the section "Myeloid Neoplasms Associated With Eosinophilia and Abnormalities of PDGFRB.
