Before the 10th treatment, the platelet count of the patient was 99 x 109/L (Figure 1a). TPO, and corticosteroids, the platelet count returned to the normal level (Figure 1b). Trastuzumab alone was used for the 11th treatment. Dental bleeding, diffuse petechiae and ecchymosis occurred again in 24 h after the infusion and the platelet count decreased to 5 x 109/L (Figure 1c).
