Synovial sarcoma of the ethmoid sinus.

INTRODUCTION

Synovial sarcoma is a malignant mesenchymal tumour typically occurring in the extremities. Its occurrence in the head and neck region, particularly in the paranasal sinuses is extremely rare.

CASE REPORT

Here, we report a case of primary synovial sarcoma of the ethmoid sinus in a 36-year-old female and review the literature of synovial sarcomas arising from the ethmoid sinus. Histopathology was essential in confirming the diagnosis. The patient underwent endoscopic excision of the tumour followed by postoperative radiotherapy.

DISCUSSION

As per our knowledge, only 2 cases of ethmoid sinus synovial sarcoma have been reported in the English literature till date. Although synovial sarcomas rarely involve the paranasal sinuses, they should be included in the differential diagnosis of paranasal sinus tumours. The accepted treatment modality is wide local excision followed by post operative radiotherapy.
