1/22. giant cell tumors of the jugular foramen.

    PURPOSE: To review the diagnosis and treatment of giant cell tumors of the jugular foramen. MATERIALS AND methods: A typical case is reported. Symptoms, signs, and diagnostic studies are reviewed. Photomicrographs and angiographic studies showing the differences between these and glomus jugulare tumors are provided. A coherent approach to their management is presented. RESULTS: These hypervascular, traditionally radioresistant tumors may cause pulsatile tinnitus, conductive hearing loss, and lower cranial nerve paresis. Angiographic studies showed a hypervascular lesion supplied by numerous small branches of the external carotid artery, making embolization difficult. Complete resection was achieved by an infratemporal fossa approach with preoperative embolization. CONCLUSION: giant cell tumors of the temporal bone may mimic glomus jugulare tumors with respect to anatomic location, cranial nerve deficits, and vascularity.

2/22. Giant-cell tumor of the skull base.

    giant cell tumors are uncommon primary bone tumors. They primarily occur in the long bones. giant cell tumors are extremely rare in the skull and head and neck. When it does occur, the maxilla and mandible are the common sites to be involved. We described two cases of giant cell tumor in the temporal bone. In the noncontrast enhanced CT, the lesion presents as a soft tissue density mass with expansion of the bone. The bony cortex is usually intact. The adjacent soft tissues and cerebral parenchyma show no infiltration or edema. The post contrast scan reveals homogenous enhancement of the mass.

3/22. Synchronous multicentric giant cell tumour: a case report with review of literature.

    Synchronous multicentric giant cell tumour (MGCT) is a rare occurrence. We report a young woman who presented with a synchronous skull and lower shaft femur giant cell tumour, who had previously received radiotherapy to both the sites, it being deemed inoperable at initial assessment.

4/22. Fine-needle aspiration cytologic diagnosis of giant-cell tumor of the sacrum presenting as a rectal mass: A case report.

    A giant-cell tumor of the sacrum is rare, and poses significant therapeutic and surgical difficulties largely because of its location. patients usually present with pain in the lower back radiating to one or both lower limbs, with or without neurological deficit. The index case presented with difficulty in defecation, in addition to pain in both lower limbs for 6 mo. The patient was seen to have a rectal mass, and a per-rectal fine-needle-aspiration was performed. The smears showed a cellular aspirate composed of a large number of osteoclastic giant cells, admixed intimately with clusters and a scattered population of mononuclear cells. Mitotic figures were not observed. Although the differential diagnosis of osteoclastic giant cell-containing lesions is broad, the presence of strong cohesiveness between the mononucleated cells and giant cells in cohesive clusters is a very helpful diagnostic feature, and was a prominent finding in the present case.

5/22. Primary malignant giant cell tumour of bone--a study of two cases with short review.

    Primary malignant giant cell tumour of bone is extremely rare. It is distinctly separate from benign metastasising giant cell tumour of bone and secondary malignant giant cell tumour which occurs in response to radiotherapy and repeated curettage of benign giant cell tumor. The tumor has high mortality rate. It usually affects lower end of femur and upper end of tibia. Two usually affects lower end of femur and upper end of tibia. Two cases, on involving upper end of tibia and other in vertebra are discussed. Extreme paucity of literature prompted to publish this article. A short review of radiological appearance, histopathological findings and treatment modalities is highlighted.

6/22. cherubism and its charlatans.

    cherubism is a rare hereditary condition characterised by progressive cystic proliferation of the mandible and maxilla in childhood, followed by post-pubertal involution of the process and jaw remodelling in adulthood. Its name is derived from the cherubic appearance that results from the jaw hypertrophy. Here, we present the case of a young boy with cherubism, in the context of his pedigree, to illustrate the clinical characteristics and their variable expression. We also seek to distinguish cherubism from central giant cell granuloma and giant cell tumour of the jaws, with which it holds a false synonymity.

7/22. anterior spinal artery syndrome after total spondylectomy of T10, T11, and T12.

    Although radical resection is the best treatment for local aggressive benign tumors or malignant tumors of the spine, total spondylectomy for lower thoracic vertebrae may cause anterior spinal artery syndrome. There are few reports in the literature in which this syndrome has been documented in association with thoracic spondylectomy, although this syndrome is the most common neurologic complication after abdominal aortic surgery. A 50-year-old woman with a giant cell tumor of the thoracic vertebrae was treated by posterior and anterior surgery. Thoracic segmental arteries from T10 to T12 had to be resected bilaterally to dissect the aorta free from the tumor. After resection of all feeding arteries to the tumor, the tumor and entire parts of T10, T11, and T12 were removed. Postoperative neurologic examination disclosed flaccid paralysis of the lower extremities and sphincter incontinence. Although pain and temperature sensation were absent, vibration and position sense were intact, showing anterior spinal artery syndrome. Intraoperative somatosensory-evoked potential monitoring only showed that transient deterioration failed to adequately reflect this neurologic injury. Major reconstructive surgery involving lower thoracic regions may cause anterior spinal artery syndrome. Somatosensory-evoked potential monitoring might not reliably predict overall neurologic outcome involving the blood supply of the lower thoracic regions.

9/22. Metachronous multicentric giant-cell tumor of the bone in the lower limb. Case report and Ki-67 immunohistochemistry study.

    Multicentric giant-cell tumors of the bone (GCTs) are rare. Little is known about the mechanisms by which these tumors spread and how 1% of GCT turn out to be multicentric. We report the case of a 19-year-old woman with metachronous multiple and recurrent GCTs that were unusual in their pattern of progression along the right lower limb over a 23-year period. histology showed no evidence of malignant transformation. The treatment was repeated curettage and packing with cement. This did not permit a wide surgical margin, but avoided amputation and preserved full limb function. We tested the proliferation index marker Ki-67 in the tumor specimens. Ki-67 expression was limited to the mononuclear cell component of the tumors. The proliferation index was similar in each new tumor and higher in recurrences for each location. In this case, proliferation was initially low in the new tumor location, despite the time difference and independent from the initial clone evolution. Proliferation index increased in recurrent GCTs after marginal margin resection.

10/22. Segmental amputation for recurrent malignant bone tumors of the distal femur.

    We describe an alternative method for lengthening a short femoral stump after wide amputation of a malignant bone tumor of the distal femur in two patients. The method consists of two procedures during the operation. The first procedure is amputation of the affected cylindrical segment of the involved limb. The second procedure is elongation of the amputation stump using the tumor-free segment of the ipsilateral lower leg as a free composite osseous myocutaneous graft. Both patients had good function and were satisfied with the results with no complications or tumor recurrence 4 years postoperatively. We think the segmental amputation is a good procedure that results in a longer functional stump in patients who have above-knee amputation.
