title: Endobronchial metastases of fibrosarcoma and non-Hodgkin's lymphoma.
abstract: Endobronchial metastases of extrapulmonary malignant tumors are rarely encountered. Herein, we have reported two cases of endobronchial metastases from nonpulmonary tumors. The first case was a 32-year-old female patient who underwent surgery for a sclerosing epitheloid fibrosarcoma in her left thigh in 2007. Metastatic bilateral parenchymal nodules in her lungs were seen on thorax CT. Bronchoscopy revealed a mass plugging, particularly in the openings of the anterior and lateral basal segments of the left lower lung lobe. Pathological examination of the biopsies was interpreted as fibrosarcoma metastasis. The second case was a 49-year-old male patient who complained of cough, weight loss, excessive sweating, and fatigue. A 7 × 8 cm, irregular limited soft tissue density in the right middle lobe of the lung that showed air bronchogram and cystic regions was detected on thorax CT. Bronchoscopy was performed. Pathological examination of the bronchoscopic materials taken from the mass that had obstructed the entrance of the middle lobe revealed a large B cell diffuse lymphoma.
