A peripheral smear examination revealed abundant platelet clusters and normal leukocyte distribution and red cell morphology (Figure 2).
Dense bodies are absent in platelets with electron microscopy. Glycogen deposit area (thin arrow), open canalicular system (thick arrow), and electron-dense areas are not surrounded by membrane (white arrow), as observed in platelet cytoplasm.
