ENDOBRONCHIAL METASTASIS FROM A PRIMARY UTERINE OSTEOSARCOMA IN A PATIENT WITH MULTIPLE-MYELOMA - REPORT OF A CASE

We present herein the case of a 75-year-old woman with multiple myeloma who underwent a left lower lobectomy for endobronchial metastasis from an uterine osteosarcoma. She had initially been admitted to our hospital for chemotherapy more than 1 year earlier, soon after which a primary uterine osteosarcoma was discovered and a total abdominal hysterectomy and bilateral salpingo-oophorectomy performed. One year after the operation, the patient developed hemoptysis. A flexible bronchofiberscopy demonstrated a polypoid mass obstructing the left basal bronchus, and computed tomographic scans showed three pulmonary nodules. Surgery was performed to control the hemoptysis. At thoracotomy, two metastatic nodules were identified in the left lower lobe, and the endobronchial extension of the tumor was resected en bloc with the left lower lobe. The tumor was diagnosed as lung metastasis from the uterine osteosarcoma. Although further lung tumors have recently appeared, the patient has remained well for the 3 years since her last operation without any hemoptysis.
