Synovial Sarcoma Arising in the Chest Wall Following Ten Years Unexplained Chest Pain

Synovial sarcomas are the fourth most common malignant soft-tissue tumors, and typically develop in para-articular locations of the extremities. Other less common sites include the head and neck, abdominal wall, intra-abdominal cavity, and mediastinum. However, the occurrence of these tumors in the chest wall is rare. In this article, we report the interesting case of a 31-year-old male with monophasic synovial sarcoma arising in the left anterior chest wall, who had sustained an unexplained, intermittent sharp pain in the area over a period of ten years before the development of the tumor. We discuss his clinical and radiological findings and include a brief review of the literature.
