Background. Most cases of squamous cell carcinoma of the lung in women are classified into peripheral type. However, in a case of endobronchial tumor complicated by total lung atelectasis, it is sometimes difficult to diagnose or determine the range of required resection. Case. A 66-year-old woman with both a smoking history (Brinkmann index; 150) and a family history of cancer complained of cough, and her chest X-ray film showed total atelectasis of the left lung. Bronchoscopy revealed a white-coated tumorous lesion in the left main bronchus, and forceps resection was performed. Pathological examination showed squamous cell carcinoma. Her lung atelectasis improved, although bronchoscopy showed a residual tumor in B3a, and computed tomography (CT) showed a low-density area from the hilum to the apex of the left upper lobe. A left upper lobectomy was performed and pathological examination of the resected tissue demonstrated papillary adenocarcinoma (pT1bN0M0) in S1+2 areas. Furthermore, obstructive pneumonia was detected between the adenocarcinoma and hilar-type squamous cell carcinoma (pT2aN1M0). Conclusion. We report a rare case of synchronous double lung cancers in the same lobe, consisting of hilar-type squamous cell carcinoma complicated by total lung atelectasis and peripheral adenocarcinoma. Resection of the tumor by bronchoscopy confirmed the cause of obstruction and we archived the complete pathological specimen of the left upper lobectomy.
