A 31-year-old otherwise healthy man was referred to hematology clinic for evaluation of long-standing thrombocytopenia. He has had thrombocytopenia since his teenage years with a platelet count in the 60 to 90 x 109/L range. He had no history of prior bleeding episodes, and had never required therapy for his cytopenia. The remainder of his CBC showed a normal white blood cell count (4.4 x 109/L) and mild anemia (hemoglobin of 11.2 g/dL; MCV of 97.0 fL). The reticulocyte count was 4.45 percent with an absolute count of 158.1 x 109/L. The peripheral blood smear is shown in the images below:
