Recently limb-salvage operation is widely used for the treatment of malignant bone tumor. But distal leg is out of range of limb-salvage operation due to its technical problem. We report satisfactory limb-salvage operation with tumor prosthesis in 3 cases of osteosarcoma of the distal tibia and fibula. Two cases involved in the tibia and 1 case in the fibula. Average age at operation was 23 years. Neoadjuvant and adjuvant chemotherapy were performed in all 3 cases. We used custom made tumor prosthesis which is designed by Seoul National University Orthopaedic Department. Overall Functional Evaluations by Enneking rating system were good in all 3 cases. All cases are CDF(continuosly disease free since the surgical procedure) state at mean follow-up 2 year and 9 months. In conclusion limb-salvage with tumor prosthesis is useful treatment modality for malignant bone tumor of distal tibia and fibula. Good functional results and few complications suggests limb salvage of distal lower leg may be replaceable with B-K amputation.

Soft tissue sarcomas are malignant tumors that arise in the extraskeletal connective tissues of the body. And the clinical behavior of soft tissue sarcomas is characterized by a tendency to extensively invade surrounding soft tissues as well as early metastatic dissemination. Difficulties were encounted when soft tissue sarcomas invade the major vessels. There are a few reprots about the reconstruction of the major vessels after resection of soft tissue sarcomas. We have treated 3 cases of the soft tissue sarcomas involving the major artery. After marginal excision of the tumor mass, the involved major artery was reconstructed with Gortex artificial vessel graft and we could salvage the patient's extremity.

Osteochondroma is the most common benign tumor in bone, consist of 40%, but, rare in spine area occupying only 2%. We report a case of osteochondroma that was in the 5th and 6th spinous process of cervical spine. We performed en bloc excisional biopsy of the bony mass. And the patient is doing well without evidence of local recurrence at 1 year after surgery. Further follow-up is necessary to observe local recurrence.

Osteoid osteoma is a benign osteoblastic tumor composed of osteoid and atypical bone, with a loose, highly vascular fibrous marrow. The tumor has been reported in most of the bones of the body, but it is infrequently localized to the hand. The scaphoid is the carpal bone involved most frequently. Typically the lesions are painful and respond to aspirin. Roentgenologic finding of the central area of lucency surrounded by sclerotic bone often is diagnostic. Block excision with bone grafting is an acceptable method of treatment. We report a case of osteoid osteoma in scaphoid with a review of the literature.

Malignant tumor of the pelvic bone has nonspecific symptom and it is not easily detected by physical examination or by radiologic study in early stage, because of its anatomical characteristics. Associated with their variety of disease entity, the treatment of malignant pelvic bone tumor is a problematic point. We have analysed 36 cases of malignant pelvic bone tumors diagnosed at the Severance hospital from 1968 to 1993 to provide a reference for diagnosis and treatment of the malignant pelvic bone tumors. We found that the chondrosarcoma(27.8%) and the osteogenic sarcoma(27.8%) were the most common type of pelvic bone malignancy, and then, in the order of incidence, there were Ewing's sarcoma(16.7%), malignant fibrous histiocytoma(11.1%). There were differences of the age distribution among each diseases and the average age was Ewing's sarcoma 20.5, osteogenic sarcoma 27.2, chondrosarcoma 40.0, malignant fibrous histiocytoma 64.8, respectively. Three of the 5 patients with low grade tumors survived(60%), whereas 3 of the 17 patients with high grade tumors survived(18%). The survival rate of the low grade malignant group was 60%, the high grade was 18%.

A Giant cell tumor of bone has unusual characteristics of pulmonary metastasis as well as local aggressiveness. Clinical courses of pulmonary metastasis of benign giant cell tumor vary including rapid growth, continuously slow growth or spontaneous regression. We report a case of extensive pulmonary metastasis of giant cell tumor of bone, which regressed spontaneouly.

The parosteal lipoma is a very rare benign neoplasm of adipose tissue having an intimate relationship to the periosteum. The parosteal lipomas comprise only 0.3% of all lipomas. We have experienced a parosteal lipoma with hyperostosis of the left tibia, in 52 years old male. We report a case of parosteal lipoma and its clinical feature with review of the literature.

Chondromyxoid fibroma is a benign tumor in adolescents and young adults. The most common location of the tumor is the proximal one-third of the tibia. Chondromyxoid fibroma accounts for less then 1% of all bony neoplasms and foot is affected in about 20% of all cases. The authors have described a case of chondromyxoid fibroma of the first metatarsal which had been recurred 7 months after curettage and iliac bone graft. En bloc resection and reconstruction of the metatarsal with autogenous iliac bone graft were performed. The results were satisfactory and the patient was free of local recurrence at two years follow-up.

The Incidence of synovial sarcoma Is very low but sarcoma Is a well-defined entity, which occurs primarily around large Joints and usually in association with tendon sheaths, bursae or the capsule. Recently we experienced a case of synovial sarcoma which invaded the right femoral vein of 433 5-year-old man. The tumor was widely excised incl ding the invaded femoral vein, and vein reconstruction was done using saphenous vein graft. The postoperative course was uneventful without intractable edema nor disability.

Kimura's disease is a mass producing uncommon chronic inflammatory process of unknown cause. It is more common among Orientals and affects particularly the young male. Sites of predilection include the head and neck regions, primarily the subcutaneous tissue and dermis. It's clinical course is benign in nature. The treatment modalities for this disease are surgical excision, steroid therapy and radiation therapy. We experienced a case of soft tissue mass in the right upper arm. It was painless and relatively movable. We performed marginal excision of the mass, which was turned out to be Kimura's disease on microscopic examination. In this case, disease recurrence was not found fifteen months after the operation.
