Eleven cases of myeloproliferative disease occurred in a group of 24 beagle dogs placed in a 60Co gamma-ray field at about 13 months of age and irradiated at an exposure rate of 5 R/22-hour day for duratior of life. Of these 11 dogs, 5 (described in this paper) were diagnosed as having erythroleukemia. The bone marrow showed marked erythroblastic hyperplasia, with maturation arrest of the erythroid elements, and increased numbers of myeloblasts and promyelocytes. The terminal peripheral blood was characterized by marked anemia and thrombocytopenia, with circulating erythrocytic precursors and abnormal erythrocyte morphology. Splenomegaly and hepatomegaly occurred in 4 of the 5 animals. In the spleens and livers of all 5, there was extensive leukemic infiltration and proliferation. The extent of leukemic involvement in other tissues and organs varied in individual dogs.

A total of 134 cases of erythroleukemia (119 from the literature and 15 of the authors' patients) were reviewed in an attempt to correlate survival with age, sex, hepatomegaly, splenomegaly, lymphadenopathy, infection, or hemorrhagic complications at initial presentation; hemoglobin (Hgb), white blood cell (WBC) count, and platelet count; percent myeloblasts in the marrow at diagnosis; and treatment regimens employed. Statistical methods included single classification analysis of variance, nonparametric analysis of variance (Kruskal-Wallis method), contingency table analysis, and correlation coefficient determination for numerical data. No significant correlation between survival and age, sex, hepatomegaly, lymphadenopathy, infection, or hemorrhagic phenomena was found. Improved survival was noted in patients without splenomegaly, and in daunorubicin-treated cases in contrast to those treated with other chemotherapeutic agents. A positive correlation between survival and initial Hgb and WBC was also noted. Erythroleukemia complicating a chronic myeloproliferative disorder had a worse prognosis than de novo erythroleukemia.

Herein, the first case of childhood erythrophagocytosis following chemotherapy for erythroleukemia in a child with monosomy 7 is reported. A 5-year-old boy presented with anemia, thrombocytopenia, and hepatosplenomegaly in whom erythroleukemia was diagnosed. Prolonged pancytopenia accompanied by persistent fever and huge splenomegaly and hepatomegaly became evident after 2 courses of chemotherapy. On bone marrow aspiration, macrophages phagocytosing erythroid precursors were observed and the diagnosis of HLH was established; additionally, monosomy 7 was detected on bone marrow cytogenetic examination. In conclusion, monosomy 7 can lead to erythrophagocytosis associated with erythroid leukemia and should be considered among the chromosomal abnormalities contributing to the association.

We present a case of pure erythroleukemia, diagnosed at autopsy, in a dysmorphic premature infant who died of multiorgan failure within 24 hours of birth. Dysmorphic features included facial and limb abnormalities with long philtrum, microagnathia, downturned mouth, short neck as well as abnormal and missing nails, missing distal phalanx from the second toe, and overlapping toes. Internal findings included gross hepatomegaly and patchy hemorrhages in the liver, splenomegaly, and cardiomegaly; and subdural, intracerebral, and intraventricular hemorrhages. Histology revealed infiltration of bone marrow, kidney, heart, liver, adrenal, lung, spleen, pancreas, thyroid, testis, thymus, and placenta by pure erythroleukemia. Only 6 cases of congenital erythroleukemia have been previously reported with autopsy findings similar to those of this case. The dysmorphic features, although not fitting any specific syndrome, make this case unique. Congenital erythroleukemia and possible syndromes suggested by the dysmorphic features are discussed.
