Echinocytes and keratocytes should be considered in the differential diagnosis of spur cell anemia. Echinocytes or burr cells are spiculated red blood cells with uniform, narrow, spikelike surface projections. Spur cells have fewer spicules, and the spicules vary more in size than echinocytes. Keratocytes are acanthocytelike cells with bizarre shapes and horny projections. Differential Diagnoses.
The reticuloendothelial cells located in the blood cavities of the liver are called Kupffer cells. These cells, together with the cells of the general connective tissue and bone marrow, are capable of transforming into bile pigment the hemoglobin released by disintegrated erythrocytes.
