Synovial sarcoma (SS) is a rare tumor. It is characterized by various sites of occurrence but rarely involves the chest. The tumor may be wrongly diagnosed as benign due to its slow growth. Less than.10% of patients present with metastatic cancer. Endobronchial metastases are exceptional. Immunohistochemical examination and cytogenetic analysis allow to distinguish it from other mesenchymal tumors. The presence of SYT-SSX fusion transcript allows the diagnosis. Surgery is used for localized tumors that can be treated with radiation therapy while chemiotherapy is used for metastatic tumors. The average rate of locoregional or metastatic recurrence two years after 55 is 50%. We report the case of a 28-year old patient with metastatic SS characterized by its uncommon metastatic site. He presented with endobronchial metastasis revealing his disease, that had evolved for more than 2 years. The SS is life-threatening due to its slow and insidious growth. Prognosis is guarded. This study aimed to emphasize this atypical site for metastatic synovial sarcoma as well as to insist on the role of early diagnosis and treatment.
