Synovial sarcoma of the maxillary sinus and chest wall: An exceptional association of two synchronous rare locations, Case report

INTRODUCTION: Synovial sarcoma is a malignant tumour of mesenchymal origin with an aggressive character and a rare cervicofacial location. Its management is multidisciplinary in order to improve prognosis and survival. CASE REPORT: We report the case of two rare and synchronous localizations of monophasic synovial sarcoma of the maxilla and chest wall in a 58-year-old woman, whose management was based on exclusive chemotherapy. DISCUSSION: The cervicofacial location of synovial sarcoma represents 3% of all locations in the body. Its clinical and radiological manifestations are aspecific. Its diagnosis is based on a combination of histological and genetic arguments. Its therapeutic management depends on the tumour stage and prognostic factors. CONCLUSION: Early diagnosis of cervicofacial synovial sarcoma allows to avoid a mutilating procedure for the patient and to improve the long-term prognosis by a good control of the tumour.
