Refractory cytopenia of childhood
Refractory cytopenia of childhood (RCC) is a subgroup of myelodysplastic syndrome (MDS), having been added to the World Health Organization classification in 2008. Before then, RCC cases were classified as childhood aplastic anemia.[1][2] RCC is the most common form of MDS in children.[3]
Clinical features
Symptoms result from underproduction of red blood cells (weakness, pallor, failure to thrive, pica), white blood cells (recurrent or overwhelming infection), and/or platelets (bleeding).
Bone marrow transplant is the only known curative treatment.
Histopathologic features
The bone marrow of patients with RCC contains islands of erythroid precursors and spare granulocytes.
