This case report provides the first ultrastructural study of an abdominal wall synovial sarcoma in the English literature, showing light and dark cells in both epitheloid and spindle cell zones.
Adds rare-site ultrastructural data to synovial sarcoma literature; leaves open need for validation before diagnostic adoption.
A case of synovial sarcoma in the abdominal wall of a 50-year-old Iraqi woman is reported. The ultrastructure of the tumor has been studied. Eight other cases of synovial sarcoma in the abdominal wall 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 women, whereas such tumors occurring in the extremities or the neck are more common in men than woman. No ultrastructural studies of abdominal wall synovial sarcomas could be found in the English literature. The ultrastructural characters of this tumor are similar to those of such tumors arising in the usual sites and the neck. However, the present study has indicated that the light and dark cells reported by earlier workers are not limited solely to the epitheloid areas but are also present in the spindle cell zones.
