Overview
The myelodysplastic syndromes (MDS, formerly known as "preleukemia") are a diverse collection of hematological conditions united by ineffective production of blood cells and varying risks of transformation to acute myelogenous leukemia. Anemia requiring chronic blood transfusion is frequently present. Although not truly malignant, MDS is nevertheless classified within the haematological neoplasms. Since the early 20th century it began to be recognized that some people with acute myelogenous leukemia had a preceding period of anemia and abnormal blood cell production. These conditions were lumped with other diseases under the term "refractory anemia". The first description of "preleukemia" as a specific entity was published in 1953 by Block et al. The early identification, characterization and classification of this disorder were problematical, and the syndrome went by many names until the 1976 FAB classification was published and popularized the term MDS.
