Bone marrow necrosis in paediatric patients.

Necrosis of bone marrow is a very rare condition with a prevalence ranging from 0.15 to 7 percent. It is mostly not compatible with life. We diagnosed four cases of necrotic marrow out of 830 bone marrow aspirations done in last five years of time. All were paediatric patients having peripheral pancytopenia. Three out of four patients expired within one month of diagnosis.
