Chronic Myelogenous Leukemia in an Infant: Serial Cytogenetic and Fetal Hemoglobin Studies

Abstract
An 8-month-old child is described who showed typical features of the adult type of chronic myelogenous leukemia including the Philadelphia chromosome. As far as known, this is the youngest patient reported with this disease. Serial fetal hemoglobin levels and cytogenetic studies are presented and discussed in terms of their possible relationship to the origin of the two types of chronic myelogenous leukemia found in childhood.
