What is pure red cell leukemia?

Chronic myeloid neoplasms are further divided into four operational categories: myelodysplastic syndrome (MDS), MPN, MDS/MPN overlap and myeloid/lymphoid neoplasms with eosinophilia and repeated rearrangements of PDGFRA, PDGFRB and FGFR1 or PMC1-JAK2; the latter mutations correspond to 5q33, 4q12, 8p11 .
