The observation of teardrop erythrocytes ranges from individual forms in a blood smear to numerous teardrop shapes in patients with marrow fibrosis and/or extramedullary hematopoiesis, often yielding a leukoerythroblastic blood smear. Peripheral smear; Complete blood count - peripheral; CBC - peripheral. The three main types of anemia are iron deficiency anemia (the most common type), thalassemia, and anemia of chronic disease. Myelophthisis: displacement of normal hematopoietic tissue in the bone marrow by abnormal cells (malignancies) or fibrosis, leading to bone marrow crowding and pinching of RBCs as they as pushed out of the bone marrow. Elliptocytes: Red blood cells are cigar or pencil shaped with parallel sides and an area of pallor. Commendations to SofiaDeo on providing a fine example. Eventually, these abnormal cells crowd out normal, healthy cells in the marrow and, along with scarring within the marrow, disrupt the production of red and white blood cells and platelets.

By comparing the sequence of DNA in cancer cells with the DNA in normal cells, doctors can find genetic changes that are unique to the cancer cells and may be driving the growth of the patient's cancer. Natelson EA, Chughtai-Harvey I, Rabbi S. Hematology. Medically reviewed by Doru Paul, MD. The abnormal hemoglobin causes red blood cells to assume a sickle shape, like the ones seen in this photomicrograph. White blood cell and platelet counts are usually abnormal, too.
