✦ Synopsis

Cervical synovial sarcoma has been reported in only 15 cases; in none o E these was there any association with a vascular structure. A patient with cervical synovial sarcoma encompassing the bifurcation of the left carotid artery underwent a left radical neck dissection, including excision of the left external carotid artery and the hypoglossal nerve. The tumor was dissected away from the common carotid and internal carotid arteries. Although the fibrous pseudocapsule of the tumor was focally infiltrated by malignant cells it appeared that the tumor had not involved the fibrous adventitia of the carotid arteries. Radiation therapy with 6000 rads tumor dose was administered t o a wide local field. There is no evidence of recurrence 1 year postoperatively. Histologic and ultrastructural findings were similar to those reported previously in a case of synovial sarcoma of an extremity. Cancer 35:483-489, 1975. YNOVIAL SARCOMA IS NOT AN UNCOMMON S mesenchymal tumor. Pack and Ariel reported it to be the most frequent sarcoma of the hands and feet.16 Stout reviewed 2095 cases of malignant tumors of the soft tissues and peripheral nerves, of which 77 (3.5%)

were synovial sarcomas.18 Van Andel,l@ reviewing che literature on treated cases of synovial sarcoma, found 450 cases and added 28 of his own. Thus, at least 555 cases of synovial sarcoma have been reported. Of this number, only 3 cases were studied by electron microscopy,5s*JO and only 1 of them in detail.6 Cervical synovial sarcoma has been reported in only 15 patients. Krugman et aL9 recently reviewed 9 cases and added 1, while Stout had 5 others in his series in 1961.l8 T h e specific cervical location of the sarcoma could be de-From the
