Simultaneous occurrence of advanced neuroblastoma and acute myeloid leukemia.  The authors report the case of a 4-year-old boy with a diagnosis of stage IV neuroblastoma ( NB ) , who had been treated with 6 cycles of cyclophosphamide , doxorubicin , cisplatin , and etoposide for 12 months . The patient reached partial remission and presented a diagnosis of acute myelomonocytic leukemia (M4 AML), confirmed by immunophenotyping. After 2 months of therapy for leukemia, the child died with both malignancies in activity. A necropsy histologically confirmed the simultaneity of the two diseases. The authors review the possibilities of this association. The review leads to the conclusion that AML can occur as a secondary malignancy after the onset of the neuroblastoma, or be suggested by a misdiagnosis. The simultaneous occurrence of both as described here is not, however, found in the literature, to the best of the authors' knowledge.
