Chromosome abnormalities in erythroleukemia [PDF]

Cancer, 1987
Erythroleukemia (EL) is a heterogeneous disease in terms of cell type affected, chromosome abnormalities found in the malignant clone, and clinical course. In this article, cases of erythroid EL from the recent medical literature are reviewed using cytogenetic criteria to distinguish such cases from those of myeloid EL.
