The antiestrogenic drug tamoxifen, used in patients with breast cancer, is associated with an increase in arterial and venous thrombotic events, the mechanism of which is not clearly understood. We report a case of a lady who presented with new bruising and prolonged bleeding following a tooth extraction 4-6 weeks after starting tamoxifen. Investigations were consistent with an acquired platelet storage pool disorder. Repeat platelet function analysis was normal, performed 3 months after discontinuation of tamoxifen. We present a previously clinically unreported effect of tamoxifen on platelet function.
用于乳腺癌患者的抗雌激素药物他莫昔芬与动脉和静脉血栓形成事件的增加有关,其机制尚不清楚。我们报告了一例女性患者,在开始服用他莫昔芬4 - 6周后拔牙,出现了新的瘀伤和出血时间延长的情况。检查结果符合获得性血小板贮存池病。在停用他莫昔芬3个月后进行的重复血小板功能分析结果正常。我们展示了他莫昔芬对血小板功能的一种此前未被临床报道的作用。
