Refractory cytopenia of childhood 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 and adolescents, accounting for approximately half of all MDS cases.^[3]

Presentation

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).^{[citation needed]}

Histopathologic features

The bone marrow of patients with RCC contains islands of erythroid precursors and spare granulocytes. In some scenarios, multiple bone marrow biopsy examinations may be recommended before a diagnosis can be established.^{[citation needed]}
