We report a new case of therapy-related acute myeloid leukemia in a child with Langerhans cell histiocytosis. This patient was previously treated with a protocol of multidrug chemotherapy, containing a relatively low dose of etoposide (total dose of 900/m(2)). Twenty-six months after the end of the therapy, the patient returned to the hospital with fever and anemia. The white blood cell count was 53 x 10(9)/L. The bone marrow examination showed massive infiltration with French-American-British acute myeloid leukemia classification M4 blast cells. The patient did not respond to an intensive treatment with high dose ARA-C and idarubicin. He died 6 months later. The cytogenetic abnormality of the blast cells was a t(11;11)(p13 -15;q23), that has not been described before in a secondary leukemia case.
