The presence of sideroblasts per se does not define sideroblastic anemia. Only the finding of ring (or ringed) sideroblasts characterizes sideroblastic anemia. anaemia with ring sideroblasts and thrombocytosis treated with lenalidomide To the Editor: Refractory anaemia with ring sideroblasts and thrombocyto-sis (RARS-T) is a rare entity and is deﬁned as an overlap syndrome with clinical and morphologic features of both myelodysplastic syndrome (MDS) and BCR-ABL-negative 2018-01-01 · The pathological hallmark of dysplasia was the presence of ringed sideroblasts detected by Prussian blue staining, in 15% or more of the erythroid progenitors. However, presence of ringed sideroblasts do not signify clonality, is sometimes reversible, and the percentage of RS do not correlate with prognosis.

Sideroblastic anemia (SA) includes a group of inherited and acquired anemias of ineffective erythropoiesis characterized by an accumulation of ring sideroblasts (RS) in the bone marrow and decreased production of mature red blood cells. 1 Ring sideroblasts are nucleated erythroblasts with a pathologic accumulation of iron granules in the mitochondrial matrix. Disease Overview: Ring sideroblasts (RS) are erythroid precursors with abnormal perinuclear mitochondrial iron accumulation. Two myeloid neoplasms defined by the presence of RS, include refractory anemia with ring sideroblasts (RARS) and RARS with thrombocytosis (RARS-T).

The woman, who had been diagnosed with ring sideroblasts associated with marked thrombocytosis, started receiving lenalidomide 10mg daily in September 2010 due to persistent transfusion dependent anaemia, thrombocytosis and with ring sideroblasts associated with marked thrombo-cytosis complicated by massive splenomegaly treated with lenalidomide resulting in resolution of splenomegaly but severe and prolonged pancytopenia.

In non-del 5q, low-risk Recently described SF3B1 mutations appear to be associated with myeloid neoplasms with ring sideroblasts [4, 5]. Lenalidomide is an immunomodulatory thalidomide analogue (IMiD) that has been shown to have some efficacy in the treatment of anemia in other myelodysplastic syndromes [6, 7], particularly when associated with deletions of chromosome 5q, where transfusion independence occurs in some two-thirds of patients . Patients with refractory anemia with ring sideroblasts and thrombocytosis (RARS-T) are difficult to treat because the cytoreductive treatment might be beneficial for the thrombocytosis component but harmful for the RARS component.

The 2016 World Health Organization classification categorizes patients with ≥ 5% RS and SF3B1 mutation as MDS-RS, in contrast to its prior MDS-RS classification (≥ 15% RS, no genotyping data).

Median number of prior therapies was 1 (range 0-3). Three patients received lenalidomide frontline therapy. Overall, 3/7 patients (43%) responded to lenalidomide therapy. Four patients were red cell transfusion dependent at the time of lenalidomide initiation. 1 DISEASE OVERVIEW. Ring sideroblasts (RS) are erythroid precursors in which after Prussian blue staining (Perls reaction) there are a minimum of five siderotic granules covering at least a third of the nuclear circumference (Figure 1). 1 The iron deposited in the perinuclear mitochondria of RS is present in the form of mitochondrial ferritin.
