Lipomas are the commonest soft tissue tumor. However, those arsing in the hand are infrequent. Lipomas in the hand that exhibit a size of more than 5 cm call giant lipoma, these are very rare only case reports and small series of this entity have been described. We could experience a case about giant lipoma of the hand which cannot easily contact, we report a case including review of literatures.

Heterotopic ossification is an abnormal bone formation after surgery or without any reason. Large joint, such as hip and knee joint, is a known most common site. Operation itself and postoperative early range of motion exercise are risk factors. We present a case of heterotopic ossification mimics neurogenic tumor after high tibial osteotomy.

Diffuse-type giant cell tumor is relatively rare than localized giant cell tumor. Moreover, diffuse type giant cell tumor is common in intraarticular area, rarely occurs at intramuscular or subcutaneous layer. We experienced 1 case of giant cell tumor within the deltoid muscle. So we report this case with review of the literatures.

Ganglion cysts that occurred within sheaths of peripheral nerves have been documented in literatures, but it is relatively rare condition. The peroneal nerve is the most common site of involvement. Other reported sites of involvement are the radial, ulnar, median, sciatic, tibial and posterior interosseous nerves. We report a case of the intraneual ganglion cyst within peroneal nerve and another case of the intraneural ganglion cyst within a medial plantar nerve that were successfully excised without neurologic complication.

Langerhans cell histiocytosis is known as one of the diseases related to excessive proliferation of normal monocytes and has the variety of clinical courses and treatment. Especially, in cases with the spine, it shows a feature of single or multiple osteolysis. According to the location, disease progression and concomitant symptom, variety of treatments (observation, radiotherapy, chemotherapy, surgery, etc.) have been attempted, however, appropriate treatment has not been established yet. The authors introduce the case of single system Langerhans cell histiocytosis which involves cervical and lumbar vertebrae simultaneously with bone marrow destruction and pathologic fracture.

6.The Failure of Polyethylene Lock of MUTARS(R) Distal Femur Tumor Endoprostheses: A Case Report.
The Journal of the Korean Bone and Joint Tumor Society 2013;19(2):74-77
The guidelines for the treatment of massive bone defects caused by bone resection due to tumors have changed from amputation to limb salvaging surgery. Limb salvaging surgery using endoprotheses is a well-established procedure. However, Aseptic loosening, infection, and mechanical defect remain significant problems. Among them, we experienced the case with a breakage of polyethylene lock of MUTARS(R) distal femur tumor Endoprostheses.

Multiple rice body formation is a complication of chronic bursitis frequently associated with seronegative rheumatoid arthritis or tuberculosis. It resembles synovial chondromatosis on imaging and clinically. We report on a pathologically diagnosed multiple rice body formation in subacromial and subdeltoid bursitis in a 44-year-old man who was treated by surgical removal and bursectomy. At 16 months after the removal, range of motion of affected shoulder was normal. No evidence of recurrence of rice body in plain X-ray and ultrasonography. Multiple rice body formed in chronic subacromial and subdeltoid bursitis could be treated with surgical removal and bursectomy successfully.

Extraskeletal chondroma is a benign soft tissue tumor which is composed of hyaline cartilage but arises from the fibrous stroma rather than from mature cartilaginous or osseous tissue. Extraskeletal chondroma is relatively rare and occurs most frequently in the soft tissue around the joints of hands and feet. We present one case of extraskeletal chondroma in a finger of a young woman.

9.Early Result of Demineralized Bone Matrix (DBM, Genesis(R)) in Bone Defect after Operative Treatment of Benign Bone Tumor.
The Journal of the Korean Bone and Joint Tumor Society 2013;19(2):56-63
PURPOSE: This study was performed to evaluate the efficiency of demineralized bone matrix (DBM, Genesis(R)) used for bone defect after operative traetment of benign bone tumors by clinical and radiological methods. MATERIALS AND METHODS: DBM was used to treat bone defect after operative treatment of benign tumor from February 2012 to May 2013. Total 25 benign bone tumor cases (15 males, and 10 females) with mean age of 30.3 were studied. The diagnoses were solitary bone cyst in 9 cases, non ossifying fibroma in 5, fibrous dysplasia in 5, aneurysmal bone cyst in 3 and enchondroma in 3. In categorization by location of tumor, there were 5 cases of distal femur, 4 of proximal tibia, 3 of proximal femur, 3 of proximal humerus, 3 of phalanx, 2 of distal radius, 2 of hip bone, 2 of calcaneus, and 1 of scapula. Autogenous bone was used with DBM in 6 cases, and only DBM used in 19 cases. Mean periods of follow up were 8.7 months (range: 6 to 14 months). Amount of graft resorption and bone formation was observed with compare of post operation radiograph and the difference was shown by percentage. Resorption level was measured by DBM level which could be observed from simple x-ray, and bone formation level by bone trabecular formation level at impaired site. RESULTS: Twenty three cases of total 25 cases showed bone union. In the 23 cases, more than 98% DBM resorption was observed after mean 4.3 months, and more than 98% bone formation was observed after mean 6.9 months. Lesser bone defect sizes showed faster bone formation and it was statistically significant (p=0.036). But other comparative studies on other factors such as, sex, age of patients and combination of autogenous bone were no statistically significant differences in graft resorption and bone formation. And there was no significant complication in periods of follow-up. CONCLUSION: Demineralized Bone Matrix (Genesis(R)) is thought to be useful treatment for bone defect after operative treatment of benign bone tumor, however longer follow-up periods appears to be needed.

PURPOSE: The purpose of this study is to determine the usefulness of arterial embolization on sacral and pelvic giant cell tumor (GCT). MATERIALS AND METHODS: We retrospectively reviewed the medical records of 9 patients who had undergone serial arterial embolization between December 1996 and May 2008. We analyzed the clinical outcomes and therapeutic responsiveness of arterial embolization on sacral and pelvic GCT. RESULTS: Six of 9 cases showed progression of disease (PD) status, even if 5 cases showed PD status despite of additional treatments including surgery and radiation, implying that serial arterial embolization on sacral and pelvic GCT is not effective. Three of 9 cases showed stable disease (SD) or continuous disease free (CDF) status and we analyzed associated factors with these good responses for embolization by chi2 test. The number of feeding vessels under six (p=0.048) and the number of collateral arterial supply under three (p=0.048) in the first angiogram showed significant relationships with good response for embolization, while remaining tumor staining by contrast after the first embolization and repeated embolization times were not significant. CONCLUSION: Although serial arterial embolization is not an effective modality on sacral and pelvic giant cell tumors, it may be a pilot modality under narrow indication of tumors with poor vascularity at first angiogram.
