CML may precede a lymphoproliferative disorder. There are a few reports showing associating of CML with multiple myeloma and we report a known CML case that transformed into a full-blown multiple myeloma. This patient had more than 69% of infiltrating myeloma cells in her bone marrow and Philadelphia chromosome was detected in 18 out of 42. However, the probable presence of some myeloma cells with classic Philadelphia-positive chromosome could be proposed. https://acta.tums.ac.ir/index.php/acta/article/view/2631 https://acta.tums.ac.ir/index.php/acta/article/download/2631/2613
