Giant cell tumour of ilium.

Most common tumours of ilium are chondrosarcoma and reticulum cell sarcoma. Giant cell tumour commonly presents at the ends of long bones. It is quite uncommon to find osteoclastoma in flat bones, especially ilium. This is the only case of osteoclastoma of ilium seen during the last 7 years in this institution and is reported for its rarity.

A case of pulmonary metastases of synovial sarcoma surviving for a long period after active surgery.

The patient was a 24-year-old woman. She underwent marginal excision of synovial sarcoma originating in the right femoral soft tissue at the age of 18, followed by local radiation therapy and chemotherapy. At the age of 20, abnormal shadow was indicated in bilateral lungs on plain roentgenography of the chest, and she underwent open-chest surgery for excision of bilateral pulmonary metastatic tumors. She was subjected to bilateral thoracotony repeatedly thereafter for a total of 5 times, and all of the metastatic foci detected in each operation were resected. Consequently, she has been surviving for a long period of about 7 years. The therapeutic outcome of tumor of bone soft tissue is greatly affected by its pulmonary metastasis. Although the therapeutic outcome has recently been improved by large dose chemotherapy and active excision of metastatic foci in the lung, survival time in the case of synovial sarcoma, giant cell sarcoma and Ewing's sarcoma is not very long yet. In the present study, we observed a patient who had lung metastasis of synovial sarcoma of which prognosis is generally considered poor has been surviving for a long time of 7 years owing to active excision of pulmonary metastatic foci. The relation of the present prognostic factors to those in the past were compared.

Cytogenetic abnormalities in a rare case of giant cell osteogenic sarcoma.

The cytogenetic analysis of a rare, nonirradiated case of giant cell tumor of bone with osteogenic sarcoma transformation is presented for the first time in a 19-year-old female. Telomeric associations involving 4p, 8p, 11p, 14p, 17p, 17q, and 20q were observed. Additionally, monosomy 13, 11p abnormalities and marker chromosomes were identified in tumor cells. Chromosome 11 involvement, particularly 11p translocations and 11p telomeric associations, were frequently observed in the tumor cells obtained from our patient, which suggests that chromosome 11p may play a role in the development of giant cell osteogenic sarcoma.

Breast sarcoma with giant cells and osteoid. A case report and review of the literature.

Breast sarcomas with giant cells and osteoid are rare and usually fatal. They should be distinguished from carcinomas with sarcomatous metaplasia. Our case is presented together with eight similar ones reported in the English literature. Their clinical, radiologic, gross, and histologic characteristics are analyzed. Most patients died within 1 1/2 years of diagnosis, survival apparently being related to the size of the tumor. Diagnosis is delayed because the tumor can be confused clinically and radiologically with a large fibroadenoma. Awareness of this problem, fine-needle aspiration, and computerized tomography may lead to earlier diagnosis and, consequently, improved survival. In our case, immunohistochemical studies supported the notion that the lesion was a primary sarcoma, rather than a carcinoma with sarcomatous metaplasia.

Primary tumors of the mandible. A study of 49 cases.

Forty-nine cases of primary tumors of the mandible have been reviewed. The anatomic location, pathologic features, sites of metastases, survival rates, and treatment methods were evaluated. Lesions studied included ameloblastoma, osteogenic sarcoma, reticulum cell sarcoma, fibrosarcoma, chondrosarcoma, myxosarcoma, epidermoid carcinoma, adenocarcinoma, and giant cell sarcoma. An in-depth discussion of primary osteogenic sarcoma of the mandible is presented. Because of upper cervical lymph node metastases in two cases of osteogenic sarcoma of the mandible, an upper neck dissection should be considered in the primary treatment. Also presented in this study are the first reported cases or primary myxosarcoma of the mandible and giant cell sarcoma of the mandible. Recent methods of treatment of ablative resection of the mandible followed by immediate or delayed repair are discussed. A revised technic for mandibular replacement which has met with success in six of seven cases is presented.
