The concomitant presence of BCR-Abl1 and JAK2/CALR mutations in Myeloproliferative neoplasms (MPNs) is rare. The clinical presentation of Chronic Myelogenous Leukemia (CML) and Ph-negative MPN may vary, but  CML seems to play a dominant role, so patients usually receive treatment with tyrosine kinase inhibitor (TKI) only. The second Ph-negative MPN becomes evident under the selective pressure of the TK.I.
