title: Synovial sarcoma of the abdominal wall: a case report and study of its fine structure.
abstract: A case of synovial sarcoma in the abdominal wall of a 50-year-old Iraq female is reported. The ultrastructure of the tumor has been studied. Eight other cases of synovial sarcoma in the abdominal wall which reported in the English literature up to 1978 have been reviewed. Synovial sarcomas in the abdominal wall tend to occur with a much greater frequency in females in contrast to such tumors in the extremities or the neck which tend to occur with a much greater frequency in males. No ultrastructure studies of abdominal wall synovial sarcomas could be found in the English literature. Ultrastructure characteristics of this tumor were similar to those arising in the usual sites and in the neck. However, the present study has indicated that the light and dark cells reported by earlier workers are not solely limited to the epitheloid areas but are also present in the spindle cell zones.
