Abstract
We reported two resection cases of pleomorphic carcinoma of the lung . In case 1, an abnormal mass shadow was found on the chest X-ray of a 65-year-old male. After right upper lobectomy and chest wall resection, the tumor was found to measure 6 cm and was diagnosed as a pleomorphic carcinoma because imagings showed sarcomatous components consisting mainly of spindle cells and giant cells . About 4 months after surgical operation, multiple liver metastases were found. In case 2, a 46-year-old woman complained of hemosputum . An huge abnormal shadow was found on chest X-ray and we resected the right upper lobe and performed partial resection of the middle lobe. Histological findings showed numerous giant cells, thus it was diagnosed as pleomorphic carcinoma . About 2 months after surgical operation, multiple brain metastases were found . Both patients had recurrence soon after operation.
