title: [Peripheral microthrombotic purpura associated with acute promyelocytic leukemia in pregnancy. A light and electron microscopic study].
abstract: A case is presented of a pregnant patient in the 28th week of gestation with promyelocytic leukemia and an unusual thrombohemorrhagic skin lesion. Ultrastructural examination revealed a microthrombotic purpura. Reduced coagulation factors increased during heparin treatment. The exacerbation of disseminated intravascular coagulation is explained by a hypercoagulable state in pregnancy in association with the as yet unknown etiology of "promyelocytic fibrinopathic leukemia".
