Differentiating between myelodysplastic syndromes myelodysplastic syndromes: (my-eh-lo-diss-PLASS-tik SIN-dromez) A group of disorders where the bone marrow does not work well, and the bone marrow cells fail to make enough healthy blood cells. Myelo refers to the bone marrow. Dysplastic means abnormal growth or development. People with MDS have low blood cell count for at… , myeloproliferative neoplasms such as primary myelofibrosis, and myelodysplastic syndromes/myeloproliferative neoplasm overlap syndromes can be challenging due to diagnostic similarities among these disorders. While there is some overlap in important risk stratification variables in these chronic myeloid neoplasms, prognostic scoring systems used for individual disorders are distinct. Use this reference card to draw a more clear distinction between the disorders and to help risk-stratify patients.
