ABSTRACT
Endobronchial metastasis (EBM) from extrapulmonary primary malignancy is a rare entity. Although the most common site of metastasis of osteosarcoma is the lungs, EBM remains a rare occurrence. Cough and dyspnea are the most common symptoms. A significant number of patients are asymptomatic, making the diagnosis without any radiographic imaging challenging. CT scan of the lung, along with bronchoscopy and biopsy, is the mainstay of diagnosis and staging. A 36-year-old man presented with small cell osteosarcoma of the left maxillary region and was treated with surgery and adjuvant chemotherapy. The patient presented 8 years later with axillary metastasis and was found to have lung metastasis on further workup. Bronchoscopy and biopsy proved an EBM that was debulked by hot snare technique. The patient was then started on chemotherapy for recurrent small cell osteosarcoma.
