[Myeloid leukemia with myelofibrosis (author's transl)].
Myelofibrosis is observed in 1/5 of the cases of C.M.L. It consists of reticulin fibers with few collagen and no osteosclerosis. It involves signs which usually indicate the extension of the myelosis to other organs and other types of cells: hepatosplenomegaly, erythroblastosis, thrombocytemia. Its prognosis is always bad. In one third of the cases, myelofibrosis develops early, and in two third it is late. Chimiotherapy is not responsible for it. These forms of C.M.L. with myelofibrosis appear as a special type of myeloproliferative disorder apart from the true C.M.L. and the true osteomyelofibrosis.
