[A case of surgically treated simultaneous bilateral squamous cell carcinoma of the lung].

A case of simultaneous, bilateral squamous cell carcinoma of the lung was presented. One located in right basal bronchus had mediastinal lymph node metastasis even though primary lesion was localized within the bronchial wall. So right lower lobectomy with R 2 lymph node dissection was carried out. The left one located in the left basal bronchus was treated using laser preoperatively, which revealed its location and extension. Sequentially S6 segmental sleeve resection was carried out and preserved his residual lung function. Six months later, the third primary lung cancer was found in left B3. We discussed about diagnosis and treatment of the multiple lung cancer and emphasize that bronchoplastic procedures in segmental level is available for treatment of multiple lung cancer.
