Abstract

Head and neck synovial sarcoma is rare. We report the case of a 71-year-old man who presented with progressive dysphagia, odynophagia, shortness of breath on exertion and hoarseness of voice. Nasendoscopy revealed a smooth, non-fungating, non-ulcerative mass arising from the left lateral pharyngeal wall. CT showed a well-defined, heterogenous enhancing lesion arising from the left pyriform fossa. Initial biopsy taken was inconclusive and patient underwent a transcervical complete excision of the tumour, where histopathological analysis confirmed the diagnosis of monophasic synovial sarcoma of the left pyriform fossa. This patient also received adjuvant radiotherapy postoperatively and remained disease free 1 year after completion of treatment.
