title: Benign tumors and tumor-like lesions of the lung.
abstract: We detail an investigation of the diagnosis and operative method for benign tumors and tumor-like lesions of the lung. In benign tumors, the preoperative diagnosis was almost the same as the postoperative one. In tumor-like lesions, the correlation of preoperative and postoperative diagnosis was poor. Since 1986, no patient with benign tumors has undergone invasive methods, but this has been required in some tumor-like lesions. Malignant tumors are easily distinguished from benign tumors but difficult from tumor-like lesions, preoperatively. Therefore, open biopsy is necessary in cases of suspicious malignancy. Then small invasive procedure should be selected due to the possibility of benign tumors.
