Refractory anaemia with ringed sideroblasts associated with marked thrombocytosis (RARS-T) with superimposed 5q-syndrome.

Refractory anaemia with ringed sideroblasts associated with marked thrombocytosis (RARS-T) is a rare entity belonging to myeloproliferative/myelodysplastic syndromes. Myelodysplastic syndrome (MDS) with isolated del(5q) is a category of MDS characterized by better prognosis and specific morphology. Herein we describe a 69-year-old male with anaemia and thrombocytosis presenting with coexisting features of both these rare diseases.
