Background. Pulmonary carcinosarcoma is a rare malignant lung tumor that tends to occur in heavy smokers and elderly men. The prognosis is poor, and there is no established method of treatment. Case. A never-smoking 71-year-old woman was admitted to our hospital because of dyspnea. Chest X-ray showed an abnormal shadow in the left lung field. Chest computed tomography showed a mass occupying the left main bronchus with atelectasis of the left upper lobe. Bronchoscopy showed a mass that was covered by necrotic tissue in the left main bronchus. A transbronchial biopsy did not result in a definitive diagnosis. Because lung cancer was suspected, surgery was performed. The pathological findings revealed pulmonary carcinosarcoma with mixed components of squamous cell carcinoma with keratinization and osteosarcoma with osteoid. The tumor recurred early after surgery, but recurrent tumors were well-controlled. The patient is currently alive at about three years after surgery. Conclusion. We herein report a treated case of pulmonary carcinosarcoma in a never-smoking elderly woman.
