Primary orbital calcified synovial sarcoma: a case report.

A 32-year-old woman presented with a progressively increasing recurrent swelling of the left eye. An orbital tumor was detected and histologically classified as a synovial sarcoma, confirmed by immunohistochemistry and electron microscopy. Isolated cases of synovial sarcoma have been reported in the retroperitoneum, mediastinum, pharynx and orofacial region. However, the orbit is an extremely rare site. The authors report a case of recurrent primary orbital calcified synovial sarcoma in a young lady treated with surgery and radiotherapy.
