Introduction:
CML is a myeloproliferative neoplasm characterized by a translocation
between chromosomes (9, 22), resulting in a BCR-ABL fusion gene with
tyrosine kinase activity. The CML-BP can transform into acute
lymphoblastic leukemia (ALL) as well as acute myeloblastic leukemia
[1]. In 2016, WHO has included AML with BCR/ABL+ gene as a separate
provisional entity in its latest classification of myeloid neoplasms
[1,2]. We report a case of CML-BP in a middle aged gentleman that
posed a challenge to diagnose and differentiate it from de novo AML due
to lack of a definite clinical criteria in such clinical scenarios
[2].
