    Description / Table of Contents: Summary In addition to an increase of the erythropoesis and myelopoesis and an increase of the reticulum cells a 5-year-old boy with erythroleukemia showed immunological phenomena: positive Coombs' test, hypergammaglobulinemia, nucleophagocytosis and normoblasts with a reticulum cell showing central storage which were arranged in a rosette-like manner. Genuine LE-cells could not be demonstrated. These findings correspond to the “syndrome resembling lupus-erythematosus.” Chromosome analysis of 250 bone-marrow cells in the final stage of hemoblastosis which could not be affected by treatment shows a mosaic of at least 3 cell lines: 46 XY/46, XY, C-, r+/47, XY, C-, 2r. The authors discuss the cytogenetic findings of the cases with erythroleukemias hitherto examined. Hypodiploidias are predominant.
    Notes: Zusammenfassung Bei einem 5jährigen Jungen mit Erythroleukämie fanden sich neben der gesteigerten Erythro- und Myelopoese sowie einer Vermehrung von Retikulumzellen immunologische Phänomene: positiver Coombs-Test, Hypergammaglobulinämie, Nukleophagozytose und rosettenartig angeordnete Normoblasten mit zentral speichernder Retikulumzelle. Echte LE-Zellen waren nicht nachzuweisen. Die Befunde entsprechen dem “Lupus-erythematodes-ähnlichen syndrom”. Die Chromosomenanalyse von 250 Knochenmarkzellen im Finalstadium der therapeutisch unbeeinflußbaren Hämoblastose zeigte ein Mosaik von mindestens 3 Zellinien: 46 XY/46, XY, C-, r+/47, XY, C-, 2 r. Die zytogenetischen Befunde der bisher untersuchten Fälle von Erythroleukämien serden diskutiert. Hypodiploidien überwiegen.
