Abstract

Synovial sarcoma is a highly aggressive malignancy with a 10-year disease-free survival of around 50%. Synovial sarcoma accounts for 5 to 10% of all soft tissue sarcomas. It is more common in young people and adolescents and it is seen in lower extremities, especially around the knee. The prognosis of the disease is worse in the elderly population. Microscopic imaging, positive staining of epithelial markers and molecular study are required to confirm the the presence of the disease. We present a 44-year-old male patient with a history of falling from the same level and presenting with only shoulder pain. Further investigations have shown that our patient is a rare form of biphasic synovial sarcoma originating from the pulmonary system, which is rarely reported in the literature.
