RESUMO
The 1st case was a 74-year-old male diagnosed as femoral neck fracture. Biopsy of the bone revealed metastatic adenocarcinoma. Chest computed tomography (CT) showed a mass lesion located in the right lower lobe. With a diagnosis of primary lung cancer (cT2N1M1), two-staged operation was performed. Pathological diagnosis was pleomorphic carcinoma [pT2N1M1 (OSS), stage IV]. He died 8 months after surgery due to metastasis to the thoracic spine. The 2nd case was a 80-year-old female who complained of lateral chest pain. Chest CT revealed a tumor in the right hilar region, which was diagnosed as adenocarcinoma by transbronchial lung biopsy. Only thoracic drainage was performed since metastases to the brain and the rib were demonstrated. She died 2 months after admission. Autopsy revealed pleomorphic carcinoma of the lung with metastasis to the brain, costa and mediastinal lymph nodes.
