Therapy related CMML: a case report and review of the literature

Therapy related chronic myelomonocytic leukemia (t-CMML) is rare. We report a 23-year-old female who developed acute fulminant hepatic failure after drug overdose. She underwent ABO incompatible orthotopic liver transplant. She received cyclophosphamide along with other immunosuppressants. Seven years later, she was diagnosed with t-CMML-2 with 45XX,-7 karyotype. She received 4 cycles of azacitidine and proceeded with allogeneic bone marrow transplant. This is the first a case of t-CMML reported in a liver transplant recipient. In this article, we also summarize all reported cases of t-CMML, and we review therapy related MDS in recipients of solid organ transplant.
