1/248. Meningeal chondrosarcomas, a review of 31 patients.

    We reviewed the literature to study the clinical features, the management and the outcome of meningeal chondrosarcomas. We included 31 patients in this review: 22 were mesenchymal and nine were non-mesenchymal. The mean age was 27 years and 64% arose from the cranial meninges. The treatment was mainly total surgical excision. Adjuvant therapy was given to 36% of patients. Spinal meningeal chondrosarcomas had a better prognosis (81% 1-year survival and 45% 3-year survival). There were no pathognomonic clinical or radiological features. We concluded that the best management of meningeal chondrosarcomas is total surgical excision whenever possible, followed by combined course of radiotherapy and chemotherapy as soon as possible.

2/248. Synovial sarcoma in the parapharyngeal space: case report and review of the literature.

    We encountered a rare case of synovial sarcoma in the parapharynx of a 47-year-old Japanese man. This patient presented with an enlarging tumor in the right side of his neck that had grown progressively over a 4-week period. Radiological examinations revealed that the tumor arose from the parapharyngeal space. The tumor could not be completely removed at surgery. Metastasis to the lumbar vertebra was detected postoperatively. The patient underwent three courses of chemotherapy and the delivery of palliative radiation to the lumbar vertebra without success. The patient died of lung metastasis 7 months after surgery.

3/248. bone marrow metastases in disseminated alveolar rhabdomyosarcoma: case report with ultrastructural study and review.

    A case of desseminated alveolar rhabdomyosarcoma in an 18-year-old male with leuco-erythroblastic anaemia is described. Numerous bizarre malignant cells, including frequent multinucleated giant cells, were seen in bone marrow aspirates, and osteolytic lesions appeared late in the clinical course. The primary site of the neoplasm remained undertermined during life and also at necropsy, which revealed minute pulmonary metastases and extensive lymph nodal, pleural and skeletal deposits. The diagnosis was confirmed on necropsy tissue by ultrastructural examination which demonstrated numerous thin (5 nm) and thick (15 nm) intracytoplasmic filaments in tumour cells, sometimes organized in bundles; scattered dense Z-band-like bodies, and rod-shaped structures were also seen. The fine structure of the rhabdomyosarcoma in the present case is compared with previous ultrastructural studies. Elongated, thick intracytoplasmic filaments whose diameter corresponds to that of myosin myofilaments are strong evidence for rhabdomyoblastic differentiation and are considered to be the sine qua non of a positive electron microscopic diagnosis of rhabdomyosarcoma. Orgaized bundles of filaments and Z-band-like dense bodies are usually present, and rod-shaped structures are found infrequently, but none of these are necessary for the ultrastructural diagnosis.

4/248. Ewing's sarcoma presenting as a posterior mediastinal mass: a lesson learned.

    Thoracic vertebral body hemicorpectomy and chest wall resection was performed in a 17-year-old male patient with a posterior mediastinal tumor thought to be neurogenic in origin. No preoperative tissue diagnostic endeavor was made. Final pathologic diagnosis showed this tumor to be Ewing's sarcoma. This communication alerts the thoracic surgeon to the need for definitive diagnosis of posterior mediastinal masses with vertebral body involvement, particularly in children. induction chemotherapy is the accepted standard of management of these sarcomas.

5/248. Spinal manifestation of metastasizing leiomyosarcoma.

    STUDY DESIGN: Case report. OBJECTIVE: To provide additional information on possible relations between uterine and spinal manifestations of leiomyosarcoma. SUMMARY OF BACKGROUND DATA: Spinal metastases and primary spinal manifestation of leiomyosarcoma and other malignant smooth muscle tumors are rarely observed. methods: Clinical and radiologic follow-up of a patient with a spinal tumor. RESULTS: A 46-year-old women had rapidly progressive paraplegia caused by an extramedullary lesion in the extradural space at T2-T3, with spinal cord compression. After surgical decompression, the resected tumor was histologically classified as a leiomyosarcoma. Diagnostic work-up failed to detect the primary tumor site. Previous medical history had been uneventful except for hysterectomy 3 years earlier for a leiomyoma. Extended necroses and focal metaplasia were already described in the hysterectomy specimen indicating malignant disease; however, it was not definitely diagnosed. Multiple leiomyosarcoma metastases developed 22 months later. CONCLUSIONS: In retrospect, the origin of the leiomyosarcoma that manifested in the thoracic spine of the patient must be reconsidered. Rather than a primary dural leiomyosarcoma, this tumor represented the first evidence of recurrence of a missed diagnosis of early-stage uterine leiomyosarcoma.

6/248. Cervical epidural rhabdomyosarcoma with a leukemia-like presentation in an aged patient--case report.

    A 77-year-old female presented with rhabdomyosarcoma manifesting as leukemia-like indications. Neuroimagings detected cervical and paravertebral masses. Immunohistochemical study of the surgically excised mass lesion from the cervical spine established the correct diagnosis. This leukemia-like presentation of rhabdomyosarcoma requires a multidisciplinary approach to establish the correct diagnosis and treatment.

7/248. Metastatic cardiac angiosarcoma of the cervical spine. Case report.

    STUDY DESIGN: A case report of metastatic cardiac angiosarcoma of the cervical spine. OBJECTIVES: To show that this rare spine tumor behaves in the same manner as an arteriovenous malformation and embolization, which can allow for successful spine surgery, and to discuss the natural history and rarity of this tumor. SUMMARY OF BACKGROUND DATA: Primary angiosarcoma of the heart is a very rare tumor, with fewer than 200 reports in the English literature and nothing reported in the spine literature. RESULTS: The patient in this study initially sought treatment for neck pain, left arm pain, and weakness 17 months after cardiac surgery and subsequent chemotherapy. A cervical computed tomography scan demonstrated a C5 lytic vertebral body tumor with intracannilicular extension and cord compression. An anterior cervical approach was made, but the tumor was too vascular to resect, and surgery was aborted. The C5 vascular vertebral body metastasis subsequently was embolized successfully by an interventional neuroradiologist. reoperation via an anterior approach with corpectomy, cadaveric fibula, and anterior locking plate internal fixation was successful, producing marked improvement in the patients' symptoms. CONCLUSION: Spinal involvement by primary cardiac angiosarcoma is very rare, and this is only the second operative case ever reported. The vascular nature of this tumor makes it behave in a manner similar to that of a high-flow arteriovenous malformation. Surgery should not be undertaken before preoperative angiography and embolization. The dismal prognosis for this rare malignancy is discussed.

8/248. Occipitocervicothoracic fixation for spinal instability in patients with neoplastic processes.

    OBJECT: Occipitocervicothoracic (OCT) fixation and fusion is an infrequently performed procedure to treat patients with severe spinal instability. Only three cases have been reported in the literature. The authors have retrospectively reviewed their experience with performing OCT fixation in patients with neoplastic processes, paying particular attention to method, pain relief, and neurological status. methods: From July 1994 through July 1998, 13 of 552 patients who underwent a total of 722 spinal operations at the M. D. Anderson Cancer Center have required OCT fixation for spinal instability caused by neoplastic processes (12 of 13 patients) or rheumatoid arthritis (one of 13 patients). Fixation was achieved by attaching two intraoperatively contoured titanium rods to the occiput via burr holes and Luque wires or cables; to the cervical spinous processes with wisconsin wires; and to the thoracic spine with a combination of transverse process and pedicle hooks. Crosslinks were used to attain additional stability. In all patients but one arthrodesis was performed using allograft. At a follow-up duration of 1 to 45 months (mean 14 months), six of the 12 patients with neoplasms remained alive, whereas the other six patients had died of malignant primary disease. There were no deaths related to the surgical procedure. Postoperatively, one patient experienced respiratory insufficiency, and two patients required revision of rotational or free myocutaneous flaps. All patients who presented with spine-based pain experienced a reduction in pain, as measured by a visual analog scale for pain. All patients who were neurologically intact preoperatively remained so; seven of seven patients with neurological impairment improved; and six of seven patients improved one Frankel grade. There were no occurrences of instrumentation failure or hardware-related complications. In one patient a revision of the instrumentation was required 13.5 months following the initial surgery for progression of malignant fibrous histiosarcoma. CONCLUSIONS: In selected patients, OCT fixation is an effective means of attaining stabilization that can provide pain relief and neurological preservation or improvement.

9/248. Low-grade malignant perineurioma of the paravertebral column, transforming into a high-grade malignancy.

    A demarcated 6 x 5 cm right paravertebral tumor at the level of T6 in a 39-year-old male was removed surgically. Histologically, the tumor consisted of monomorphous benign-looking, low-cellular spindle cells embedded in desmoplastic stroma. Ten years later, the tumor recurred locally with metastasis to systemic organs, including the occipital skin. Malignancy was histologically evident by the increased cellularity, cellular atypia and mitotic activity. The patient died of respiratory failure at the age of 49. Retrospectively reviewed, the primary lesion was low-grade fibrosarcoma-like spindle cell tumor, with secondary transformation into a highly malignant form. The differential diagnoses included sclerosing epithelioid fibrosarcoma, low-grade fibromyxoid sarcoma and malignant peripheral nerve sheath tumor. Immunohistochemically, the spindle cells in the primary and recurrent tumors consistently expressed epithelial membrane antigen, vimentin, type 4 collagen and laminin. The tumor cells in the present case showed a differentiation toward perineurial cells, which are normally positive for these immunohistochemical markers. Hence, the appropriate diagnostic term should be 'malignant perineurioma', a subtype of malignant peripheral nerve sheath tumor.

10/248. Simultaneous anterior-posterior approach for excision of malignant paraspinal tumor and subsequent reconstruction. Technical note.

    In cases of primary malignant extradural tumors of the spine, the main goal of the surgery is en bloc resection and reconstruction of the spine. After placing the patient in the lateral position, an en bloc resection of a chondrosarcoma that arose from the right seventh rib head and invaded the adjacent vertebra was performed using a simultaneous anterior-posterior approach followed by spinal reconstruction. The technical details are reported. Paraspinal malignant tumors of the thoracic spine can be safely removed en bloc and the spine reconstructed using this approach.
