Myelodysplastic neoplasm with low blasts and SF3B1 mutation (MDS-LB-SF3B1) has undergone significant classification changes in the past year with the publication of the 5th edition of the World Health Organization Classification of Tumors of Haematopoietic and Lymphoid Tissues and the International Consensus Classification. This article reviews the basic biology of SF3B1, iron metabolism, and dysfunction that leads to the formation of ring sideroblasts. It highlights neoplastic and non-neoplastic considerations to the differential diagnoses. Finally, a review on the evolution of the prognostic scoring system and treatment regimens that are available to patients with a diagnosis of MDS is presented.

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
