Alveolar soft part sarcoma is a clinically and morphologically distinct soft tissue tumor that was first defined and named by Christopherson et al in 1952. Since 1953, alveolar soft part sarcoma invading bone have been reported sporadically. We experienced a case of alveolar soft part sarcoma with metastasis to femoral shaft, which was treated by wide resection & vascularized fibular strut graft.
