myelosis

 [mi″ĕ-lo´sis]
formation of a tumor of the spinal cord.
aleukemic myelosis agnogenic myeloid metaplasia.
erythremic myelosis erythroleukemia.
nonleukemic myelosis agnogenic myeloid metaplasia.

er·y·threm·ic my·e·lo·sis

a neoplastic process involving the erythropoietic tissue, characterized by anemia, irregular fever, splenomegaly, hepatomegaly, hemorrhagic disorders, and numerous erythroblasts in all stages of maturation (with disproportionately large numbers of less mature forms) in the circulating blood; postmortem studies reveal primitive erythroblasts and reticuloendothelial cells, not only in hemopoietic organs, but also in the kidneys, adrenal glands, and other sites. Acute and chronic forms are recognized, but in the latter there is less prominence of the immature cells; the former is also called Di Guglielmo disease (or syndrome) and acute erythremia.Synonym(s): Di Guglielmo disease

(er'i-thrē'mik mī-ĕ-lō'sis)
A neoplastic process of erythropoietic tissue, characterized by anemia, irregular fever, splenomegaly, hepatomegaly, hemorrhagic disorders, and numerous erythroblasts in blood. Acute and chronic forms are recognized, but in the latter there is less prominence of the immature cells; the former is also called Di Guglielmo disease and acute erythremia.
Synonym(s): erythraemic myelosis.

erythremic myelosis

a myeloproliferative disorder of cats, rarely other species, manifested by marked anemia but with marked anisocytosis without an accompanying polychromasia. Large numbers of rubricytes can be found in the bone marrow and sometimes in the circulation. The condition has been compared to Di Guglielmo syndrome in humans. Feline leukemia virus has been implicated in the etiology.

blast form of erythremic myelosis
previously called reticuloendotheliosis, the predominant cell type is more primitive.
