Abstract
Synovial sarcoma (SS) primary to the pleura is an extremely rare tumor. So far, only
nine cases have been reported in pediatric patients. However, none of these patients
was found to have a conglomeration of tumors. Here, we report a case of 16-year-old
female with monophasic SS and synchronous occurrence of left paraspinal ganglioneuroma
and a right paraovarian cystadenoma. A next-generation sequencing genetic panel revealed
a novel variant of unknown significance in the MET gene. The occurrence of multiple
different tumors in a young patient with a novel genetic variant in a known oncogene
(MET) may suggest a possibility of a hitherto unknown cancer predisposition syndrome.
We also present a brief review of primary pleural SS reported in pediatric patients.
