Vaginal bleeding as a presenting symptom of synovial sarcoma

A case is reported of a woman who presented with bleeding from a vaginal extension of a synovial sarcoma. The patient was unaware of the primary tumor in the left thigh and histologically, the tumor resembled a carcinosarcoma. Awareness of the physical and radiologic findings allowed the correct pathologic diagnosis to be made. The manner of presentation of the tumor is believed to be unique.
