背景与目的肺淋巴管癌病(PLC)是肺转移癌的一种特殊类型,极易误诊为其他疾病。本研究通过总结PLC的临床特征,拟提高对此病的认识,减少或避免误诊。方法收集整理经尸检证实,但生前均被误诊的7例PLC患者的临床资料,对其临床表现及影像学资料进行回顾性分析,总结本病的特点,为临床诊断提供参考。结果7例PLC患者临床表现均为干咳、气短、呼吸困难,X线胸片表现为双肺纹理增多,有模糊片状影,散在小结节、网状纤维条索影。结论PLC的临床表现无特异性,当恶性肿瘤出现呼吸系症状时,应注意考虑此病,以免误诊。
Background and Objective Pulmonary lymphangitic cancer (PLC) is a special type of lung metastasis that can be easily misdiagnosed as other diseases. This study summarizes the clinical features of PLC, intends to raise awareness of the disease, reduce or avoid misdiagnosis. Methods The clinical data of 7 PLC patients who were confirmed by autopsy but were misdiagnosed before were retrospectively analyzed. The clinical features and imaging data were analyzed retrospectively. The characteristics of this disease were summarized and provided a reference for clinical diagnosis. Results The clinical manifestations of 7 PLC patients were all dry cough, shortness of breath and dyspnea. X-ray showed the increase of double lungs, fuzzy patchy film, scattered nodules and reticular fiber strips. Conclusion The clinical manifestations of PLC is nonspecific. When malignant tumors have respiratory symptoms, care should be taken to consider the disease to avoid misdiagnosis.
