SYNOVIAL SARCOMA, A RARE TUMOR OF THE LAR YNX (CASE-REPORT AND DIFFERENTIAL DIAGNOSTIC CONSIDERATIONS)

The synovial sarcoma of the larynx is a very rare tumour. Only six cas es have been published so far in international literature. We describe a synovial sarcoma of the larynx in a 53-year old patient. Laryngecto my and neck-dissection were performed, followed by adjuvant radiothera py. 16 months after therapy neither locoregional recurrence nor lung m etastases have occurred. Clinically, an attempt can be made to differe ntiate a synovial sarcoma from a squamous cell carcinoma based on the appearance of the surface epithelium. It is still a problem to safely establish the diagnosis of a synovial sarcoma on the basis of a biopsy . The poor prognosis of this tumour requires radical surgical removal. The effects of radiation are discussed controversially.
