Lenalidomide induced durable remission in a patient with MDS/MPN-with ring sideroblasts and thrombocytosis with associated 5q- syndrome. Alshaban A(1), Padilla O(2), Philipovskiy A(1), Corral J(1), McAlice M(1), Gaur S(1). Refractory anemia with ring sideroblasts associated with marked thrombocytosis (RARS-T) is a hematologic malignancy that often results in transfusion dependency and a hypercoagulable state. This rare disease currently lacks formal guidelines for treatment; however, various case reports have demonstrated efficacy in the use of lenalidomide. Refractory anemia with ring sideroblasts associated with marked thrombocytosis (RARS-T) is a hematological malignancy that combines features of both a myeloproliferative and myelodysplastic disorder.

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.
