[Management and follow-up of acute myeloblastic leukemia with translocation (8; 21). Report of one case].

We describe the management and follow-up of a 20-year-old male with acute myeloblastic leukemia with translocation (8; 21) [t (8; 21)]. A quantitative polymerase chain reaction for t(8; 21) in bone marrow was performed at diagnosis and after three consolidations with high doses of cytarabine. Currently, the management of this type of leukemias has been oriented towards the early detection of relapse.

[Association between von Willebrand disease and angiodysplasia].

Von Willebrand factor (vWf) is a fundamental multimeric plasma glycoprotein in the coagulation process. Its function is to mediate platelet adhesion and to stabilize circulating factor VIII. A functional or quantitative alteration of vWf gives rise to von Willebrand disease (vWD).
