Neck metastasis of a myxoid liposarcoma of the lower extremity

We report the clinical features of two cases presenting metastatic neck tumors (in the anterior neck and submandibular regions) secondary to myxoid liposarcoma of the lower extremity. Both cases underwent repeated resection of primary., legions of the lower extremities because of recurrences. Such repeated surgical procedures are thought to be a risk factor for distant metastasis resulting from hematogeneous dissemination of tumor cells, although there is considerable debate about multicentricity N7 versus metastasis in liposarcomas. Where possible therapy for liposarcomas should initially comprise complete and wide resection of the lesions. Combined therapy consisting of surgery and postoperative radiation and chemotherapy should be investigated in the future. (C) 2004 Elsevier Ireland Ltd. All rights reserved.
