CELL-DYN Ruby

Auto-immune Hemolytic Anemia

Description

This patient was a 76 year old man with a history of chronic lymphocytic leukemia, initially diagnosed 2 years ago. Over the past three weeks the patient had noted progressive fatigue and shortness of breath with exertion. Laboratory examination showed a severe anemia and a disproportionately low RBC count. MCV was strongly increased, due to the massive reticulocytosis (see case 36). Morphology showed numerous spherocytes as well as polychromatic macrocytic erythrocytes. Additional studies revealed 35 % reticulocytosis, an elevated LDH (960 IU/L), and a positive direct Coomb’s test.
