Microangiopathic haemolytic anaemia in cancer patients with bone marrow infiltration.

Abstract

Eight patients suffering from wide-spread malignancies presented with a severe microangiopathic haemolytic anaemia (MHA) without gross evidence for coagulation abnormalities. The common feature in these patients was bone marrow infiltration with malignant cells, suggesting a pathogenic link between bone marrow carcinosis and red cell destruction. Furthermore, it is concluded that MHA is a rare complication of malignancy and a terminal syndrome rather than an early manifestation of the disease.
