Elliptocytes, also known as ovalocytes or cigar cells, are abnormally shaped red blood cells that appear oval or elongated, from slightly egg-shaped to rod or pencil forms. They have normal central pallor with the hemoglobin appearing concentrated at the ends of the elongated cells when viewed through a light microscope. The ends of the cells are blunt and not sharp like sickle cells.[1]
