Chronic myeloid leukemia (CML) with p190 BCR-ABL is rare. In some cases it is associated with peripheral monocytosis, while bone marrow shows features intermediate between CML and chronic myelomonocytic leukemia. The prognosis is controversial, but in the most recent literature p190 BCR-ABL CML seems associated with a poor outcome. We report a case of p190 BCR-ABL CML characterized by moderate monocytosis, without deep molecular response (DMR) to an initial imatinib treatment. After imatinib was replaced by dasatinib, a DMR was achieved, however without appreciable effects on monocytosis.
