Malignant tumors of the hand are very rare. Between 1989 and 1998, 17 patients with malignant tumors of the hand were evaluated for clinical features, prevalence, treatment and results. The mean age was 45 years and median duration of follow-up was 38 months. A painless mass was the most common symptom and the most common lesion was the digit. Fifteen cases of soft tissue and 2 cases of bone tumor were diagnosed. On pathology, soft tissue tumors were comprised of 8 cases of malignant melanoma, 2 cases of angiosarcoma and 1 case each of malignant fibrous histiocytoma, malignant peripheral nerve sheath tumor, extraskeletal chondrosarcoma, and squamous cell carcinoma. Bone tumors were metastatic tumors and each originated from the rectal cancer or lung cancer. Lymph node involvements were noted in 4 cases of malignant melanoma and 1 case of squamous cell carcinoma. Six cases of metacarpo-phalangeal joint disarticulation and 4 cases of phalanx amputation were performed. Wide excision, ray amputation and below-elbow amputation were also performed. Three cases expired due to metastasis and progression of the original lesion. Among the surviving 14 cases, a malignant melanoma had metastasis on the axillary lymph node and 13 cases showed no local recurrence or metastasis during the follow-up.

Primary malignant bone tumors of the scapula are very rare, and little literature is available regarding their characteristics and outcome. We studied the clinical characteristics, and outcome of patients with primary malignant bone tumors of the scapula. From 1979 to 2008, we treated 7 patients at our institute (4 men and 3 women; chondrosarcoma 3, Ewing's sarcomas 3, Osteosarcoma 1). The mean age was 45 years (range, 5~65 years). The follow-up period was 2 - 180 months. Six patients were performed operations: total scapulectomy 3, partial scapulectomy 1, forequarter resection 1, total resection of the shoulder girdle (Tikhoff-Linberg procedure) 1. No-operative treatment was chosen for one patient with a limited life expectancy. Local recurrence occurred in one patient. Distant metastasis occurred in 3 patients. Of the 7 patients, 4 patients are died because of propagation of the disease. Three patients were alive and apparently disease-free, and these patients were evaluated for functional results with the functional evaluation system of the International Society of Limb Salvage (ISOLAS). Functional result of partial scapulectomy was excellent, however, the function after total scapulectomy or Tikhoff-Linberg procedure is severely impaired. Our study indicates reconstruction procedure needs to be reconsidered following total scapulectomy or Tikhoff-Linberg procedure.

Metastaic bone tumors are usually accompanied with severe pain. The treatment modalities for this pain are so variable that patients are sometimes afraid of using them. Salmon calcitonin has a function to increase beta-endorphines followed by increasing the blood level of prostaglandin and thromboxan A2, which results in analgesic effect. This drug also has been known to decrease bone resorption. There were a few reports that parenteral use of salmon calcitonin decrease the pain from metastatic bone tumor. We wanted to know the effectiveness and tolerability of nasal spray of salmon calcitonin in relieving bone pain with metastatic tumor. We analyzed the effectiveness in the aspects of pain, sleep, performance status, mobility, supplementary analgesic use. The biologic effect of salmon calcitonin was analysed with CBC, Ca/P, BUN/Cr, uric acid. Simple radiography, alkaline phosphatase, osteocalcin, pyrilink-K were used as parameters for bone change. Eighteen cases of metastatic bone tumors took nasal spray of salmon calcitonin($Miacalcic^{(R)}$, 200IU/day) for 4 weeks, to relieve bone pain. With Wilcoxon Matched-Pairs Signed Ranks Test, we could find pain decreased significantly at 3 week and mobility become improved at 4 week of salmon calcitonin use. Other parameters didn't show any significant changes. We think the analgesic effect is mainly due to effect not on the local bone lesion but on the central nervous system, and that increased dose of salmon calcitonin can induce earlier and stronger analgesic effect.

Plasmacytoma is a plasma cell neoplasm that locally infiltrates a bone or spreads to extramedullary areas. A new World Health Organization criterion defines solitary plasmacytoma of bone as a localized bone tumor consisting of plasma cells identical to those seen in plasma cell myeloma, which is manifested as a solitary osteolytic lesion in a radiological evaluation. Primary tumors of the sternum are generally malignant, and solitary plasmacytomas of the sternum are very rare tumors. We present herein the case of a patient who had a primary sternal tumor with solitary plasmacytoma and no evidence of multiple myeloma.

In certain low-grade malignant bone tumors such as chondrosarcoma or frequent recurrent benign bone tumors as ossifying fibroma, radical treatment may provide a good chance for cure. And large bony defect after the radical treatment can be filled with the massive bone graft. Recent advances in clinical microsurgery have made free vascularized bone graft a clinical reality, and Taylor in 1975, first reported the technique of free vascularized fibula graft for the reconstruction of large tibial defect with excellent clinical results. We tried wide excision and free vascularized fibula graft in 5 patients with ossifying fibroma and one patient with chondrosarcoma from January 1984 to December 1994 and followed for more one year. The shortest bony defect was 7cm and the longest bony defect was 20cm and mean bony defect was 13cm. All patients were evaluated clinically and roentgenographycally on basis of functional recovery and bony union. All patients showed satisfactory functional recovery with sound bony union and showed bony hypertrophy. And, local recurrence was not seen.

Gastric cancer is a major cause of cancer-related mortality. At the time of diagnosis, majority of the patients usually have unresectable or metastatic disease. The most common sites of metastases are the liver and the peritoneum, but in the advanced stages, there may be metastases to any region of the body. Bone marrow is an important metastatic site for solid tumors, and the prognosis in such cases is poor. In gastric cancer cases, bone marrow metastasis is usually observed in younger patients and in those with poorly differentiated tumors. Prognosis is worsened owing to the poor histomorphology as well as the occurrence of pancytopenia. The effect of standard chemotherapy is unknown, as survival is limited to a few weeks. This report aimed to evaluate 5 gastric cancer patients with bone marrow metastases to emphasize the importance of this condition.

Aspiration of lytic bone lesions is an excellent diagnostic test in the initial evaluation of primary bone tumor. However, cytologically, it can be difficult to differentiate osteosarcoma (OSA) from other bone neoplasms, including fibrosarcoma, chondrosarcoma, synovial cell sarcoma, malignant fibrous histiocytoma and malignant peripheral nerve sheath tumor. The purpose of this study is to introduce alkaline phosphatase (ALP) staining to differentiate OSA from other mesenchymal tumors. Tumors actively producing bone are specifically positive for ALP staining. Unstained, cytologic specimens were incubated for 10 minutes with nitroblue tetrazolium chloride/5-bromo-4-chloro-3-indolyl phosphate toluidine salt-phosphatase substrate. Among 20 cases of cytology specimen, 14 were positive for ALP staining and histopathology, 6 were negative for ALP staining and histopathology. ALP staining was 100% sensitive and specificity for the diagnosis of OSA. Aspirate cytology with ALP staining was a simple, fast, safe and accurate diagnostic test for the evaluation of suspected OSA lesions in dogs.
