INTRODUCTION: Chondrosarcomas are the second most frequent primary malignant bone tumors, after osteosarcomas . They are also the most common primary malignant chest wall tumors. 5-15% of chondrosarcomas are located in the thoracic wall .The most frequent site of metastasis are the lungs; other sites include the bones, brain, regional lymph nodes, and liver . Although, most pulmonary metastases present with multiple peripheral, round nodules of varying size on roentgenograms, certain metastatic sarcomas such as osteosarcomas may have unusual presentation i.e., lymphangitic carcinomatosis, endobronchial metastasis, or pneumothorax Surgical resection remains the primary mode of therapy.

CASE PRESENTATION: A 40 year-old male patient was admitted wıth cough to our hospital.He had undergone hemipelvictomy for pelvic chondrosarcoma four years ago.Chest x-ray and thorax CT showed a 44x60 mm diameter mass in the rigth upper lung and consolidation of left paracardiac location.Fiberoptic bronchoscopy showed an endobrochial metastasis in lingula which was confirmed as metastatic chondrosarcoma by histopathology.He underwent left upper lobectomy and rigth upper lobectomy after a month , is alive and followed-up for 8 months

DISCUSSION: Endobronchial metastasis is defined as documented extrathoracic malig­nancies metastatic to the endobronchus within a bronchoscopically visible range. Although the clinical and radiologic findings of endobronchial metastasis are simi­lar to primary lung cancer, treatment and prognosis may be different.

CONCLUSIONS: As chondrosarcoma rarely presents with endobrochial metastases , we discuss the clinical, radiological and histopathologic features of this case in the light of literature data.
