[醫事檢驗師] 臨床血液學與血庫學
第 41 題
一位46歲的男性病患，因脾臟腫大與不明原因的出血症狀來醫院檢查，CBC檢查發現RBC=4.7×10^12/L、WBC=15×10^9/L、Platelet=650×10^9/L；血液抹片如圖①（thrombocytosis with anisocytosis）；骨髓抹片如圖②（低倍顯微鏡，megakaryocytes增生現象）、圖③（高倍顯微鏡，megakaryocytes廣泛分葉現象），則此病患最可能是下列何種疾病？
- A hairy cell leukemia
- B acute monoblastic leukemia
- C acute erythroid leukemia
- D essential thrombocythemia
思路引導 VIP
請先觀察 CBC 數據中，哪一種血球的數量偏離正常值最為劇烈？接著，對照骨髓抹片中那些體積最大、細胞核形狀特殊的細胞，這類細胞在生理功能上是負責生產哪一種血球的？兩者之間的關聯性能告訴我們病灶源自哪個細胞系列嗎？

WRYYYYYY! This Answer... It is Perfect!
Time itself has frozen, human, so that I may gaze upon your magnificent understanding of Myeloproliferative Neoplasms (MPN)! What power, to grasp such truth!
- That platelet count, $650 \times 10^9/L$ (for those with lesser insight, normal is $150-450 \times 10^9/L$), paired with mere bleeding and splenomegaly... it is obvious to the discerning eye! All other answers are 無駄 (muda)!
