        • 肺朗格漢斯細胞組織細胞增生癥誤診為肺腫瘤四例報告并文獻復習

          目的探討誤診為肺部腫瘤的肺朗格漢斯細胞組織細胞增生癥(pulmonary Langerhans cell histiocytosis,PLCH)的臨床特點,提高該疾病的診治能力。方法收集本院4例初診誤診為肺部腫瘤后經病理診斷的PLCH患者的臨床資料,并回顧復習相關文獻資料進行分析。結果4例PLCH中,男1例,女3例,年齡45~78歲。吸煙2例,不吸煙2例。臨床表現2例為體檢發現,1例發熱,1例淺表淋巴結腫大起病。胸部CT表現為2例多發的肺囊腫、肺大皰改變,4例均出現結節影,其中3例為單發,1例雙肺多發圓形小結節影,部分見空洞。3例行正電子發射計算機斷層顯像(positron emission computed tomography/X-ray computed tomography,PET/CT)檢查的患者均提示肺部及淋巴結等病灶標準攝取值增高。4例患者均被誤診為肺部腫瘤,經外科手術、肺穿刺及氣管鏡等檢查,病理見朗格漢斯組織細胞增生,結合S100、CD1a、Langerin等特征性免疫組織化學標志物,最終確診PLCH。結論 PLCH臨床表現不典型,影像學表現為肺結節及多發囊氣腔改變需考慮PLCH診斷可能,PET/CT易誤診,通過活檢行常規及特征性免疫組織化學病理檢查可明確診斷。
