  • Clinical Analysis on Pulmonary Langerhans’ Cells Histiocytosis and Literatures Review

    ObjectiveTo investigate the clinical features of Pulmonary Langerhans' cells histiocytosis (PLCH). MethodsFour cases of PLCH diagnosed by histopathologic examination between August 2004 and September 2013 were retrospectively analyzed. ResultsFour male patients aged from 19 to 46 year old, including three smokers. The main symptoms were chest tightness, cough, and dyspnea. Pneumothorax was presented in two cases, and tuberculosis was in one. The chest high resolution CT (HRCT) revealed lung cysts, nodles, and reticular changes predominantly in the upper and middle lung fields. The pathological Langerhans' cells infiltration were found in the histological biopsy of lesions of the 4 cases. All of the patients were positive in the immuno-histological staining for the S-100 and CD1a antigens. Two cases were positive in Langrin staining (other two patients didn't underwent the staining). Two of the 4 patients were given oral steroid, and the symptoms were improved in one of them. The case with pulmonary tuberculosis improved in symptoms and CT results showed the absorption of the lesion after anti-tuberculosis therapy. Three cases were not followed up. ConclusionPLCH patients were mainly young adults, often presented with chest tightness, cough, and dyspnea. The clinical features of chest HRCT are bilateral cysts, nodules and reticular changes. The disease may be defined by the finding of pathologic Langerhans' cells or the positive staining for CD1a antigens or Langerin.

  • 肺朗格汉斯细胞组织细胞增生症误诊为肺肿瘤四例报告并文献复习

    目的探讨误诊为肺部肿瘤的肺朗格汉斯细胞组织细胞增生症(pulmonary Langerhans cell histiocytosis,PLCH)的临床特点,提高该疾病的诊治能力。方法收集本院4例初诊误诊为肺部肿瘤后经病理诊断的PLCH患者的临床资料,并回顾复习相关文献资料进行分析。结果4例PLCH中,男1例,女3例,年龄45~78岁。吸烟2例,不吸烟2例。临床表现2例为体检发现,1例发热,1例浅表淋巴结肿大起病。胸部CT表现为2例多发的肺囊肿、肺大疱改变,4例均出现结节影,其中3例为单发,1例双肺多发圆形小结节影,部分见空洞。3例行正电子发射计算机断层显像(positron emission computed tomography/X-ray computed tomography,PET/CT)检查的患者均提示肺部及淋巴结等病灶标准摄取值增高。4例患者均被误诊为肺部肿瘤,经外科手术、肺穿刺及气管镜等检查,病理见朗格汉斯组织细胞增生,结合S100、CD1a、Langerin等特征性免疫组织化学标志物,最终确诊PLCH。结论 PLCH临床表现不典型,影像学表现为肺结节及多发囊气腔改变需考虑PLCH诊断可能,PET/CT易误诊,通过活检行常规及特征性免疫组织化学病理检查可明确诊断。
