title: [Preleukemia].
abstract: The six cases of Preleukemia (or Preleukemic States) are described. The peripheral blood was characterised with Pancythopoenia in 5 and bicytopoenia in 1 patient. Morphological alterations of Erythrocytes were present in all cases. The Bone Marrow was hypercellular in 3 and hypocellular in 3 patients. Erythropoiesis was megaloblastic or partly megaloblastic in 5 cases, with "ring" sideroblasts present in all cases. The percentage of Leukemic blast cells was as follow: 0, 5, 6, 10, 30 and 33. The duration of the preleukemic phase varied from 3-53 months. With the manifestations of overt Acute Nonlymphatic Leukemia the agressive therapy was applied. The results were poor in 5 patients (the survival 1, 5-4 m.). Only one survived more than 60 months and is still in full remission.
