refractory anaemia

(Science: haematology) A form of myelodysplasia which primarily affects the red cell production by the bone marrow.

In some cases the developing red cells show an internal ring of iron granules. These cells are called sideroblasts. Refractory anaemia and refractory anaemia with sideroblasts are the most common forms of myelodysplasia.

Origin: Gr. Haima = blood
