Synovial sarcoma of the larynx in a child: case report and histological appearances.

Synovial sarcoma of the larynx is extremely rare having been reported only six times previously in the literature. We add another case report, which to our knowledge is the first recorded case in a child. We discuss the alternative approach of combination chemotherapy and radiotherapy which in this case led to a remission lasting about 3 years. The immunohistological and ultrastructural characteristics of the tumour are also presented.
