Sickle Cell Anemia
Elongated, crescent-shaped and sickle RBCs. Note target cells (arrow) and Howell-Jolly body (both due to autosplenectomy secondary to repeated splenic infarcts). (Courtesy of Dr. M. Reis)
Microangiopathic Hemolytic Anemia
Fragmented RBCs (schistocytes). Note Helmet cell and triangle-shaped cell (arrows).
Small, round, densely staining red blood cells with no central area of pallor.
Autoimmune Hemolytic Anemia
Agglutination of red blood cells (arrow).
Iron Deficiency Anemia
Microcytosis and hypochromia of red blood cells. Note increased area of central pallor.
