Extramedullary blast crisis and hemolytic anemia in a patient with t(3p+;4q-) and rapidly evolving myelogenous
We have reported the case of a patient with a rapidly evolving myelogenous leukemia associated with hemolytic anemia, extramedullary evolution, and an isolated translocation of the long arm of chromosome 4 to the short arm of chromosome 3. The hemolytic process was primarily extravascular and was not associated with pyruvate kinase or glucose-6-phosphate dehydrogenase deficiency. Although blasts were absent from the peripheral smear and represented less than 10% of the bone marrow myeloid precursors, multiple organs including the heart, liver, lungs, and spleen were infiltrated with blasts at autopsy.
