Abstract:
Cytogenetic study of a case of erythroleukemia in a 9-year-old white male showed a modal number of 72 with tetraploidy of several chromosomes and duplication of markers. The disease had a very rapid initial response to therapy. The uniqueness of this karyotype and its relationship to previously reported cytogenetic studies on erythroleukemia are discussed.
