1/537. Bone infarction complicated by sarcomatous change: a case report.A patient with a sarcoma of the tibia associated with multiple bone infarcts and a history of alcoholism, is presented. This is a rare association. The possible aetiological role of bone infarcts in relation to the development of a sarcoma is discussed.- - - - - - - - - - ranking = 1keywords = sarcoma (Clic here for more details about this article) |
2/537. Congenital infantile fibrosarcoma.Infantile fibrosarcoma is a rare tumour in the paediatric age group. It occurs mainly in children below the age of 5 years. About 200 cases have been reported in the literature so far, very few of them in new-borns. We present here a case of infantile fibrosarcoma in a 27-day-old baby.- - - - - - - - - - ranking = 1keywords = sarcoma (Clic here for more details about this article) |
3/537. Infantile fibrosarcoma. Report of two cases.We present two cases of infantile fibrosarcoma, one of which was thought to be a congenital tumour on the thigh and was initially diagnosed as a haemangioma, and the other was a tumour on the trunk. Although both recurred locally after initial surgical treatment, wide local re-excision controlled the disease without adjuvant treatment.- - - - - - - - - - ranking = 0.83333333333333keywords = sarcoma (Clic here for more details about this article) |
4/537. Low grade fibromyxoid sarcoma: fine-needle aspiration cytology with histologic, cytogenetic, immunohistochemical, and ultrastructural correlation.BACKGROUND: Although the histologic features of the recently described low grade fibromyxoid sarcoma are well established, to the authors' knowledge there are no reports in the literature describing the cytologic features of this tumor by fine-needle aspiration. Recognition of this lesion is important because of its indolent but metastasizing nature. methods: The authors retrospectively reviewed their surgical pathology files for cases of low grade fibromyxoid sarcoma with a preoperative fine-needle aspiration biopsy (FNAB); three such cases were found. Immunohistochemical studies were performed in all three tumors, ultrastructural examination was performed in two tumors, and fresh tissue for cytogenetic analysis was obtained in one tumor. RESULTS: All FNABs showed similar features. The aspirates were relatively hypocellular with an abundant myxoid background; the neoplastic cells contained oval to spindle shaped nuclei with minimal pleomorphism. No capillaries or areas of fibrous tissue were identified. Cytogenetic study of one case revealed no chromosomal abnormalities. The histologic findings were characteristic for this lesion. By immunohistochemistry the tumor cells showed diffuse and strong reactivity for vimentin only; at the ultrastructural level the neoplastic spindle cells had characteristics of fibroblasts. CONCLUSIONS: The cytologic features of low grade fibromyxoid sarcoma are not specific enough for a definitive diagnosis based on FNAB alone; however, correlating the cytologic and clinical findings can narrow the range of diagnosis. The differential diagnosis includes other myxoid lesions, in particular superficial or intramuscular myxoma and myxofibrosarcoma. In addition, the immunohistochemical and ultrastructural findings support a fibroblastic origin for this neoplasm.- - - - - - - - - - ranking = 1.3333333333333keywords = sarcoma (Clic here for more details about this article) |
5/537. Transformation of ameloblastic fibroma to fibrosarcoma.The direct transformation of an ameloblastic fibroma into a fibrosarcoma in a 16-year-old Caucasian male is reported. Although no ameloblastic epithelium was found in the recurrent tumor, the odontogenic origin of the fibrosarcoma was evident. The ameloblastic fibrosarcoma and the fibrosarcoma of identical odontogenic origin represent an entity which should be distinguished from conventional fibrosarcoma as these tumors demonstrate different clinical behaviors.- - - - - - - - - - ranking = 1.5keywords = sarcoma (Clic here for more details about this article) |
6/537. Pulmonary fibrosarcoma in childhood: fiber-optic bronchoscopic diagnosis and review of the literature.Primary pulmonary fibrosarcoma is a rare malignant tumor in childhood. In the absence of metastases, complete resection is curative. An 8-year-old boy suffered from unresolving pneumonia due to an obstructing lesion in the left main bronchus. Cytology of the bronchoalveolar lavage fluid and histology of bronchial biopsy revealed the diagnosis of pulmonary fibrosarcoma. The tumor did not respond to chemotherapy, and a total lobectomy with sleeve resection was performed with complete removal of the neoplasm. Two years after the operation the child has no evidence of disease.- - - - - - - - - - ranking = 1keywords = sarcoma (Clic here for more details about this article) |
7/537. Primary pure intratesticular fibrosarcoma.Testicular sarcoma appears to be a rare stromal tumor usually of indolent course with potential for distant metastases. A pure primary intratesticular fibrosarcoma in a 71-year-old male is presented. By the time the tumor became evident metastases had already occurred widely. The course was rapidly fatal. A review of the literature yielded only one case reported previously. The present case illustrates that pure fibrosarcoma occurs occasionally as a stromal tumor and may be associated with a dismal prognosis. The diagnosis of pure fibrosarcoma should be made only after extensive sampling of the testicular tumor to rule out an associated germ cell component. The differential diagnosis also includes the fibroma of gonadal stroma origin and the unclassified sex cord-stromal tumor with a predominance of spindle cells.- - - - - - - - - - ranking = 1.3333333333333keywords = sarcoma (Clic here for more details about this article) |
8/537. Primary meningeal fibrosarcoma: a particular neuroradiological presentation.Primary meningeal fibrosarcoma is a rare malignant tumor of the central nervous system. About seventeen cases have been reported in the literature since 1980. We present the case of a patient whose initial neuroradiological manifestation of primary meningeal fibrosarcoma was an en plaque meningioma. Fifteen months later, he developed a dramatic clinical deterioration and coma. CT scan revealed a large frontal lesion. The mass was completely removed and histological examination was characteristic of meningeal fibrosarcoma.- - - - - - - - - - ranking = 1.1666666666667keywords = sarcoma (Clic here for more details about this article) |
9/537. diagnosis of primary fibrosarcoma of the lung by fine-needle aspiration and core biopsy.Primary pulmonary sarcomas are uncommon neoplasms. Primary fibrosarcoma of the lung is extremely rare, and only 53 cases have been documented in the literature to date. To our knowledge, the diagnosis of primary lung fibrosarcoma by fine-needle aspiration cytology has never been reported. We report a case of pulmonary fibrosarcoma diagnosed by fine-needle aspiration cytology and core biopsy. The neoplasm consisted of interweaving fascicles of minimally atypical spindle cells with slender nuclei and scant cytoplasm. Positive immunohistochemistry for vimentin along with nonreactivity of tumor cells for keratin, S100 protein, desmin, alpha-smooth muscle actin, and CD34 supported the the diagnosis. The diagnosis was later confirmed by histologic and ultrastructural findings following lobectomy. A meticulous clinical search for a possible primary neoplasm elsewhere was unsuccessful, and lung was established as the primary site. Fine-needle aspiration cytology and core biopsy are reliable methods for establishing a diagnosis of fibrosarcoma.- - - - - - - - - - ranking = 1.5keywords = sarcoma (Clic here for more details about this article) |
10/537. Burn scar sarcoma.Malignancies developing in burn scars have been known for a long time and are generally epidermoid carcinomas although a few sarcoma cases have been reported. A case of fibrosarcoma developing in the burn scar was presented in this report and the literature reviewed.- - - - - - - - - - ranking = 1keywords = sarcoma (Clic here for more details about this article) |
