title: [Acute myeloblastic leukaemia following Ewing's sarcoma: iatrogenic complication? (author's transl)].
abstract: A seven-year-old child treated for a Ewing's sarcoma of the pelvis with a combination of radiotherapy and sequential polychemotherapy (vincristine, cyclophosphamide, adriamycine and procarbazine), developed an acute myeloblastic leukaemia fourty-one months later. The leukaemia was preceded by a ten-month period of isolated moderate neutropenia. Several possible explanations of the aetiology of this association are discussed, with particular emphasis on current concepts of the histogenesis of Ewing's sarcoma, and more particularly the possible role of radiotherapy and cytotoxic treatment in the induction of acute leukaemia.
