Abstract
Retroperitoneal synovial sarcomas are very rare. The authors describe a 39-year-old male with a primary retroperitoneal synovial sarcoma showing a monophasic pattern. Immunohistochemically, the tumor cells were positive for cytokeratin AE1/AE3, epithelial membrane antigen, vimentin, S-100 protein, CD99 and calretinin. The differential diagnosis, clinical evolution and principles of treatment are shortly discussed.
