肺结节病与中央型肺癌的鉴别诊断

分析２９例Ｉ期肺结节病和１１６例中央型肺癌的临床特点。肺结节病多发于４１岁左右女性，而肺癌则多发于５５岁左右男性。前者呼吸道症状较少，后者则较多。Ｘ线胸片：肺结节病多为双侧肺门淋巴结对称性肿大；肺癌多为单侧肺门淋巴结肿大，且常伴肺门肿块、肺不张和胸膜病变。纤维支气管镜所见肺结节病无特征性变化，而肺癌则可见增生性改变和充血、水肿等，病理可见癌细胞。

Differential Diagnosis between Pulmonary Sarcoidosis and Central Lung Carcinoma

Twenty-nine cases of pulmonary sarcoidosis (stage I) were compared with 116 cases of central lung carcinoma. Sarcoidosis was more common in women about 41 years old, while lung cancer in man about 55 years old. Respiratory symptoms were less presented in the former group and were more presented in the latter. The chest X-ray film showed that bilateral symmetrical hilar lymphadenopathy were more common in pulmonary sarcoidosis, and unilateral hilar lymphadenopathy with lung mass and atelectasis in lung cancer. There were no special signs in pulmonary sarcoidosis on fibrobron-choscopy, and proliferation,congestion and edema of mucosa could be found in lung cancer.
