我們在此報告一名23 歲的男性士兵，最初始於右腿疼痛，後來快速發展到危及生命的感 染性肺栓塞，感染性休克，急性呼吸衰竭的情況。最後的診斷是由甲氧西林敏感之金黃色葡 萄球菌所引起的化膿性肌炎和壞死性肺炎，此菌株可製造潘頓 - 瓦倫丁殺白細胞素(PVL)，屬 於序列型59 單基因變異 (ST59slv)。這類微生物在台灣是普遍的，通常是無生命危險的皮膚和 軟組織感染症。這是序列型59 金黃色葡萄球菌感染所造成生命威脅的第一份報告。病人經由 抗葡萄球菌和抗毒素藥物，手術引流及清創，重症監護，和多重專科合併治療之後存活。

We herein report a case involving a 23-year-old male soldier with initial right leg pain that rapidly progressed to life-threatening septic pulmonary emboli, septic shock, and acute respiratory failure. The eventual diagnosis was pyomyositis and necrotizing pneumonia caused by Panton-Valentine leukocidin-producing, sequence type 59 single-locus variant (ST59slv) methicillin-susceptible Staphylococcus aureus. This microorganism is common in Taiwan and usually causes non-life-threatening skin and soft tissue infections. This is the first report of a life-threatening condition caused by ST59slv S. aureus infection. The patient survived with antistaphylococcal and antitoxic therapy, surgical drainage and debridement, intensive care, and multidisciplinary intervention.
