Diagnosis and treatment approaches of this entity are complex and require a skilled and experienced multidisciplinary team. Authors report their experience with a case of FS of humerus showing a pathologic complete response to neoadjuvant chemotherapy based on adriamycin cisplatin and ifosfamid. This approach allowed limb-sparing surgery with an excellent functional and psychological result. Background Fibrosarcomas FS of bone represent 5 of all primary bone sarcomas 1 2 . It occurs most frequently in the middle age 1 and affects men and women with equal frequency. In addition it affects most commonly the long bones. The tumor may be either central 68 or cortical 31 1 . Fibrosarcomas can arises as a primary lesions or secondary to fibrous dysplasia to Paget s disease to bone infarcts to osteomyelitis or to postirradiation of bone and giant cell tumors GCT 3 4 . Histologically tumors are characterized by interlacing bundles of collagen fibers without any osteoid or cartilage production 1 . Differential diagnosis includes fibroblastic osteosarcoma and malignant fibrous histiocytoma MFH 5 . Surgery is the standard treatment for fibrosarcoma of bone 1 . Amputation was the primary method of therapy yielding the best curative results 1 . However by combining advanced bone imaging techniques with surgical techniques implant development and neo-adjuvant therapy limb-sparing .
