Essential thrombocythemia (ET) is one of the myeloproliferative neoplasms, characterized by persistent thrombocytosis, platelets >450,000/μL, and evident clonal abnormalities like JAK2 V617F, MPL, CALR mutation and not fulfilling WHO criteria for MDS, CML, PV, and IDA. Here we report a 24-year-old female who presented with headache and was found to have thrombocytosis with a platelet count of 2,141 × 10/μL, diagnosed as ET as per WHO criteria 2008; she required ICU admission and thrombocytapheresis with a favorable outcome.
原发性血小板增多症（ET）是一种骨髓增殖性肿瘤，其特征为持续性血小板增多，血小板计数>450,000/μL，且存在明显的克隆性异常，如JAK2 V617F、MPL、CALR突变，且不符合世界卫生组织（WHO）关于骨髓增生异常综合征（MDS）、慢性粒细胞白血病（CML）、真性红细胞增多症（PV）和缺铁性贫血（IDA）的诊断标准。在此，我们报告一名24岁女性，因头痛就诊，发现血小板增多，血小板计数为2,141×10/μL，根据2008年WHO标准诊断为ET；她需要入住重症监护病房（ICU）并进行血小板单采术，结果良好。
