A Case of Myeloid Blast Crisis of Atypical Chronic Myelogenous Leukemia / 대한혈액학회지

ABSTRACT

Atypical chronic myelogenous leukemia (aCML) has dysplastic as well as proliferative features in most instance and rarely evolves to blast crisis, so it is considered as a distinct clinical entity to classical BCR-ABL (+) CML. We experienced a patient who are diagnosed aCML and transformed to myeloid blast crisis after 17 months. Monosomy 7 and deletion of 12p were found on conventional cytogenetics.
