[Heterotopic erythropoiesis in liver transplantation]

Various conditions may restore hematopoietic activity in the adult liver. Of them, liver transplantation is of most interest. The causes and the mechanism of hematopoiesis restoral in liver grafts is not yet fully clarified. The Authors analyze the incidence of immature erythroid cells in a series of hepatic fine-needle aspiration biopsies performed in 28 patients with orthotopic liver transplant and in two clusters. The post-mortem liver examination, available in the two clusters, confirmed the ungoing hematopoietic activity.
