[Clinico-hematic study of lymphoblastic leukemia of childhood].

The authors write their personal experience in 205 children with lymphoblastic leukemia. The disease has its peak incidence between 5 and 14 years, showing a preference for females and white individuals. The clinical form of presentation was "complete" (66.8%) or "incomplete" (33.2%). Most of the symptoms were due to leukemic infiltration of bone marrow and some other tissues. The amount of leukocytes was variable; most of the cases showed anemia and thrombocytopenia. However, a few patients had normal values of hemoglobin and platelets, whose prognostic significance is discussed. After the FAB classification, the L1 variety predominated. About 3.9% of the patients showed radiological bone alterations suggesting acute leukemia.
