We report an unusual case of a primary osteosarcoma of the lung in an asymptomatic 77-year-old male, who underwent lobectomy with complete resection of the lung lesion. His pattern of relapse was to multiple lymph nodes. The first relapse was 11 weeks after lobectomy in subcarinal lymph nodes, confirmed on needle aspiration to be consistent with sarcoma. Given his excellent performance status, this was treated with radical radiotherapy to 70 Gy in 35 fractions with good control. He relapsed to other lymph node regions. A biopsy of the external iliac lymph node was done and revealed osteoid production, consistent with osteosarcoma. He received palliative radiotherapy to several nodal areas with good clinical response. We review the literature of this rare tumor with an unusual pattern of relapse.
