Erythroid proliferations in myeloid neoplasms

摘要: Prominent erythroid proliferations (in which elements comprise ≥50% of total bone marrow cells) can be seen in various hematopoietic stem cell neoplasms. The myeloproliferative neoplasm polycythemia vera exhibits effective, overexuberant erythropoiesis resulting an increased red blood mass; contrast, most other diseases characterized by predominance exhibit ineffective hemopoiesis. latter include acute leukemia (erythroid-myeloid and pure subtypes) as well some cases myelodysplastic syndromes, myeloid with myelodysplasia-related changes, therapy-related Some nonneoplastic reactive conditions may also manifest a striking predominance. In this article, we review the literature relevant to group for better understanding their clinicopathologic features surrounding controversies. We examine position neoplastic current 2008 World Health Organization Classification Myeloid Neoplasms provide recommendations how approach differential diagnosis diseases.
