Endobronchial metastases from a leiomyosarcoma of the uterus.

A 63-year-old woman presented with dyspnea, non-productive cough and chest pain. On computed tomography of the thorax, near total atelectasis of the left lung was reported. On bronchoscopic examination, a mass lesion was observed in the mucosa of the left main bronchus leading to near total obstruction. Her medical history revealed that she had been treated with total abdominal hysterectomy and adjuvant radiation therapy for a leiomyosarcoma of the uterus one year ago. She was diagnosed as having a metastatic leiomyosarcoma and was treated with palliative radiation therapy. Six months later, she presented with disseminated disease involving the thorax and the pelvis. She refused further treatment and died one month later. Patients with leiomyosarcomas of the uterus might follow an aggressive clinical course, with relatively early metastases at unusual sites.
