Abstract
Primary leiomyosarcoma of the bone is rare. Histologically, it resembles leiomyosarcoma of soft tissue. Given the rarity of this entity, its diagnosis should be made only after clinical studies and workup have excluded metastasis from other sites. Herein, we describe an additional case of primary bone leiomyosarcoma. We report a 32-year-old female patient, who presented with right knee pain and was found to have a right distal femur mass by imaging studies. Biopsy showed a neoplasm composed of fascicles of spindle cells, arranged in different patterns, with significant pleomorphism. The tumor cells were positive for smooth muscle actin, focally positive for desmin and H-caldesmon. No other masses in the body were detected by imaging studies. The diagnosis of leiomyosarcoma of the bone was rendered. Given the broad diagnostic differential of primary bone leiomyosarcoma, it is important to be aware of this rare bone tumor phenotype and of its histomorphologic and immunohistochemical features for an accurate diagnosis.

Abstract
BACKGROUND Primary leiomyosarcoma of the spine is extremely rare and lacks specific clinical symptoms. This study investigated the imaging manifestations and clinicopathological findings of primary leiomyosarcoma of the spine, aiming to improve the radiologists' understanding of the disease and reduce misdiagnoses. METHODS The clinical, imaging, and pathological manifestations in eleven patients with pathologically confirmed primary leiomyosarcoma of the spine were retrospectively analyzed. The imaging features analyzed included lesion location, shape, border, size, and density/intensity, and adjacent bone destruction status, residual bone trabeculae, vertebral compression, and contrast enhancement. RESULTS The patients' primary clinical symptom was usually focal pain. Primary leiomyosarcoma of the spine was mostly a solitary lesion and tended to occur in the posterior elements. The tumors had a lobulated shape with osteolytic bone destruction, ill-defined borders, and could involve multiple segments. Computed tomography (CT) examination showed isodense masses. Six patients showed residual bone trabeculae. Two patients had miscellany T2-weighted imaging (T2WI) signals, while the tumor and spinal cord of the remaining patients were isointense on T1-weighted imaging (T1WI) and T2WI. Among the seven patients who underwent contrast-enhanced scanning, six displayed homogeneous enhancement. Eight patients underwent gross-total tumor resection with no recurrence. CONCLUSIONS Primary leiomyosarcoma of the spine tends to be a solitary lesion in the posterior elements and appears as a lobulated mass with osteolytic bone destruction and an ill-defined border. The tumor and spinal cord can be isointense on T1WI and T2WI. Contrast-enhanced scanning displays homogeneous enhancement. The lesion tends not to recur after surgical gross-total tumor resection.

Abstract
OBJECTIVE Primary spinal leiomyosarcoma (PSL) is extremely rare. A case is presented, followed by a systematic review establishing the consensus on presentation, diagnosis, management and outcomes. Comparison being made with metastatic spinal leiomyosarcoma (MSL). METHODS A systematic review was conducted in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligibility criteria was decided upon before the literature search was conducted. Data were extracted and analysed. RESULTS 397 articles were identified, 25 articles conformed to the eligibility criteria. 34 cases were included in the analysis. PSL had a female preponderance (69.2%) with back pain being the most common presenting symptom (60.9%). Neurological signs were present in the majority (69.6%) with tumours typically being in the thoracic spine (46.9%). Diagnosis was primarily made using MRI (64.7%) and CT (55.9%), with a histological sample being obtained in all cases. Most patients underwent operative management (91.2%) with variable use of neoadjuvant and adjuvant therapies. Operative approach differed greatly and outcome following surgical management was stated in 48.4% of cases, all noting an improvement from presentation. Patient follow up was limited (median 7 months), with the majority of patients being free of disease (43.8%). CONCLUSIONS PSL diagnosis is challenging with PET-CT and histopathological sampling playing an important role. There is a limited evidence base for the treatment strategies employed but surgical management is key with generally good outcomes. Prognosis for PSL would appear to be better than MSL. There is scope for more dedicated research in PSL and MSL.

Abstract
BACKGROUND In 2020, the World Health Organization (WHO) published the 5th version of the soft tissue and bone tumor classification. Based on this novel classification system, we reviewed the current knowledge on all tumor entities with spinal manifestations, their biologic behavior, and most importantly the appropriate treatment options as well as surgical approaches. METHODS All tumor entities were extracted from the WHO Soft-Tissue and Bone Tumor Classification (5th Edition). PubMed and Google Scholar were searched for the published cases of spinal tumor manifestations for each entity, and the following characteristics were extracted: Growth pattern, ability to metastasize, peak age, incidence, treatment, type of surgical resection indicated, recurrence rate, risk factors, 5-year survival rate, key molecular or genetic alterations, and possible associated tumor syndromes. Surgical treatment strategies as well as nonsurgical treatment recommendations are presented based on the biologic behavior of each lesion. RESULTS Out of 163 primary tumor entities of bone and soft tissue, 92 lesions have been reported along the spinal axis. Of these 92 entities, 54 have the potential to metastasize. The peak age ranges from conatal lesions to 72 years. For each tumor entity, we present recommended surgical treatment strategies based on the ability to locally destruct tissue, to grow, recur after resection, undergo malignant transformation as well as survival rates. In addition, potential systemic treatment recommendations for each tumor entity are outlined. CONCLUSION Based on the 5th Edition of the WHO bone and soft tumor classification, we identified 92 out of 163 tumor entities, which potentially can have spinal manifestations. Exact preoperative tissue diagnosis and interdisciplinary case discussions are crucial. Surgical resection is indicated in a significant subset of patients and has to be tailored to the specific biologic behavior of the targeted tumor entity based on the considerations outlined in detail in this article.

Abstract
Leiomyosarcoma is a rare type of malignant soft tissue tumor and also one of the most aggressive soft tissue sarcomas. It commonly occurs in uterus, abdominal viscera, retroperitoneal space and soft tissue of the extremities. Primary osseous leiomyosarcoma is a rare condition. Furthermore, primary leiomyosarcoma of the spine is extremely rare. Only few cases have been reported. However, the treatment and outcomes remains controversial. Therefore, the objective of this case report is to illustrate the management of this extremely rare disease by using total en bloc spondylectomy (TES) procedure, which is one of a suitable option for surgical resection of the spinal tumors. In this study, we presented an unusual case of a 61-year-old female, who was diagnosed as primary leiomyosarcoma of the twelfth thoracic spine with liver metastasis, treated with total en bloc spondylectomy of the twelfth thoracic vertebra followed by chemotherapy. On last follow-up, 6 months after the surgery, the clinical outcome remained in good condition and no signs of local recurrence. In conclusion, primary leiomyosarcoma of the spine is an extremely rare and difficult to diagnosis. Immunohistochemistry studies are very important for confirmation of the diagnosis. Standard treatment remains controversial. However, surgical resection is still treatment of choice. One of the most effective surgical options is TES, which give the better outcome and minimize local recurrence, if indicate.

Abstract
Primary vertebral leiomyosarcoma in thoracic spine is extremely rare. Metastatic origin must be excluded. Wide surgical excision can result in local tumor control and long-term survival.
Introduction To describe an unusual primary vertebral leiomyosarcoma in thoracic spine. Presentation of case An isolated lesion of the T11 vertebra in a 62-year-old woman with no neurologic deficit is reported. Imaging findings indicated a nonspecific high-grade malignant lesion. TC-guided biopsy failed thus open incisional biopsy was needed. A diagnosis of low-intermediate mesenchymal sarcoma was made. A total en bloc spondylectomy of T11 was performed with three-column reconstruction. The histology and immunostaining showed the appearance of leiomyosarcoma. After diagnosis, post-operative radiation therapy was performed. Metastatic lesion was ruled out by CT scans of the chest, abdomen and pelvis, in addition to total body radionuclide scanning and 18-F-FDG-PET. After five years of follow-up, no signs of local recurrence, metastasis or distant lesions suggesting a primary lesion were observed. Discussion Vertebral primary leiomyosarcoma is exceedingly rare. Primary vertebral leiomyosarcoma diagnosis must be performed when the metastatic origin is excluded. For the treatment of primary tumors, total en bloc spondylectomy (TES) is the technique of choice to achieve marginal or wide tumor resection, decrease the risk of local recurrence and remote lesions and increase survival. Conclusions A well-planned pre-operative study and a wide surgical excision can result in local tumor control and long-term survival. This case presents the longest disease-free survival period of a primary leiomyosarcoma in spinal location after total en bloc spondylectomy.

Abstract
A 47-year-old woman presented with symptoms of low back pain and weakness in bilateral lower limbs. MRI of the spine revealed a mass arising from T11 vertebra involving neural foramina at bilateral T11-12 and right T10-11 levels with extension to the right paravertebral region. Suspecting a nerve sheath tumour, she underwent posterior spinal decompression, stabilisation and debulking, following which her neurological symptoms resolved. Histopathological and immunohistochemical evaluation revealed a leiomyosarcoma. A month later she developed sudden paraparesis and MRI revealed an increase in size of the tumour with cord compression and displacement. She underwent a repeat spinal decompression and debulking procedure after which she received adjuvant radiotherapy via volumetric modulated arc therapy, to a total dose of 45 Gy in 25 fractions over 5 weeks. MRI performed 2 months later revealed complete response and she is disease free for the past 5 months.

Abstract
RATIONALE Primary leiomyosarcoma of the bone was firstly reported by Evans and Sanerkin in 1965, whereas primary leiomyosarcoma of the vertebra is extremely rare. Because of the rarity of primary vertebral leiomyosarcoma, the diagnosis, treatment, and clinical outcome still remain controversial. Here we report a special case of primary leiomyosarcoma in the thoracic vertebra. PATIENT CONCERNS A 47-year-old female patient was admitted to our institution with the chief complaint of persistent back pain for 4 weeks. She had no symptoms of numbness, weakness, pain, and abnormal sensation in her extremities. DIAGNOSES Neurological examination on admission revealed no obvious abnormality. Magnetic resonance imaging showed a bone destruction of the T11 vertebral body and the right pedicle. Therefore, primary vertebral leiomyosarcoma was suspected. Pathological hematoxylin and eosin staining of the resected tumor revealed a diagnosis of polymorphic undifferentiated sarcoma. Furthermore, to identify the subtype of this sarcoma, the immunohistochemical staining of the tumor was performed with each of the various antibodies and the results are epithelial membrane antigen (-), H-caldesmon (-), desmin (+), smooth muscle actin (+), S-100 (-), myogenin (-), pan-keratin (-), and Ki-67 (positive rate: 20%). Finally, the patient was diagnosed as primary vertebral leiomyosarcoma. INTERVENTIONS the anterior corpectomy and autogenous iliac bone graft with instrumentation combined with the posterior spinal canal decompression and fusion with the pedicle screw system were performed through an anterior-posterior union approach. OUTCOMES Neither clinical symptoms nor signs of tumor recurrence were detected within the follow-up of 6 months. In addition, 11 cases of the primary vertebral leiomyosarcoma reported in the literature were reviewed and summarized. LESSONS Exclusion of metastatic leiomyosarcoma by various imaging modalities and histopathological examinations, especially the immunohistochemical staining with various antibodies against the epithelial and mesenchymal cell markers, are critical for establishing the correct diagnosis of the primary vertebral leiomyosarcoma. Surgical resection, especially the total en bloc spondylectomy, is the main treatment option with a good outcome, albeit with a limited follow-up duration.

Abstract
Primary osseous leiomyosarcoma of the spine is a very unusual condition, with only few cases being reported in the literature. In fact, this type of tumors arises from the smooth muscle cells and occurs usually in the uterus and the gastrointestinal tracts. If the spine should be involved, it occurs generally as a metastatic location. Location to the spine as a primary site is exceedingly rare. We present the case of a 37 years old female patient, with multiple spine levels involvement - to vertebral body and to posterior aspects of Vertebra, causing spinal cord compression syndrome. A secondary location to the skull was diagnosed one month later. Through a literature review, we analyze various aspects in the diagnosis and management of this rare entity.

Abstract
OBJECTIVE The authors studied 6 cases of osseous leiomyosarcoma of the spine. Two of these cases were of immunocompromised human immunodeficiency virus (HIV)-positive patients with Epstein-Barr virus (EBV)-associated primary vertebral leiomyosarcomas. The remaining 4 cases were of patients with leiomyosarcoma metastases to the spine. METHODS Each patient underwent surgical resection of their vertebral mass; however, the patients with the EBV-associated tumors had the best postoperative prognosis. RESULTS The HIV-positive patients have had no further local recurrence, while the other 4 patients had rapid local recurrences requiring multiple surgical interventions. Furthermore, the patients living with HIV have lived longer with fewer leiomyosarcoma-related health complications. CONCLUSIONS These findings suggest that EBV-associated vertebral leiomyosarcoma is of a less aggressive variety than metastatic leiomyosarcoma of the spine.

Abstract
Primary tumors of spine are rare accounting for less than 5% of new bone tumors diagnosed every year. These tumors may exhibit characteristic imaging features that can help in early diagnosis and improved prognosis. Plasmacytoma/multiple myeloma and lymphoproliferative tumors are the most common malignant primary spinal tumors. Hemangioma is the most common benign tumor of the spine. Computed tomography is useful to assess tumor matrix and osseous change. Magnetic resonance is useful to study associated soft tissue extension, marrow infiltration, and intraspinal extension. Confusing one tumor with the other based on only imaging findings is not uncommon. However, radiologic manifestations of these tumors need to be correlated with the age, sex, location, and presentation to arrive at a close clinical diagnosis.

Abstract
OBJECTIVE
Primary spinal osteosarcomas are rare and aggressive neoplasms. Poor outcomes can occur, as obtaining marginal margins is technically demanding; further Enneking-appropriate en bloc resection can have significant morbidity. The goal of this study is to identify prognostic variables for local recurrence and mortality in surgically treated patients diagnosed with a primary osteosarcoma of the spine.
METHODS
A multicenter ambispective database of surgically treated patients with primary spine osteosarcomas was developed by AOSpine Knowledge Forum Tumor. Patient demographic, diagnosis, treatment, perioperative morbidity, local recurrence, and cross-sectional survival data were collected. Tumors were classified in 2 cohorts: Enneking appropriate (EA) and Enneking inappropriate (EI), as defined by pathology margin matching Enneking-recommended surgical margins. Prognostic variables were analyzed in reference to local recurrence and survival.
RESULTS
Between 1987 and 2012, 58 patients (32 female patients) underwent surgical treatment for primary spinal osteosarcoma. Patients were followed for a mean period of 3.5 ± 3.5 years (range 0.5 days to 14.3 years). The median survival for the entire cohort was 6.7 years postoperative. Twenty-four (41%) patients died, and 17 (30%) patients suffered a local recurrence, 10 (59%) of whom died. Twenty-nine (53%) patients underwent EA resection while 26 (47%) patients underwent EI resection with a postoperative median survival of 6.8 and 3.7 years, respectively (p = 0.048). EI patients had a higher rate of local recurrence than EA patients (p = 0.001). Patient age, previous surgery, biopsy type, tumor size, spine level, and chemotherapy timing did not significantly influence recurrence and survival.
CONCLUSIONS
Osteosarcoma of the spine presents a significant challenge, and most patients die in spite of aggressive surgery. There is a significant decrease in recurrence and an increase in survival with en bloc resection (EA) when compared with intralesional resection (EI). The effect of adjuvant and neoadjuvant chemotherapeutics, as well as method of biopsy, requires further exploration.

Abstract
We report a case of leiomyosarcoma of the thoracic spine. Primary leiomyosarcoma is a malignant connective tissue tumor originating from smooth muscle cells. Leiomyosarcoma frequently occurs in the uterus, retroperitoneal space, gastrointestinal tract, and deep soft tissues; primary leiomyosarcoma of the bone is rare. The MR imaging including intravoxel incoherent motion (IVIM) imaging findings of the current case indicated a low diffusion coefficient and high blood flow, which were in concurrence with high cell density on histology and increased vascularity by angiography. Although some benign tumors such as osteoblastoma and giant cell tumor would show similar findings on IVIM imaging, these additional imaging features may narrow the differential diagnosis of spinal tumors.

Abstract
OBJECT Leiomyosarcoma is a smooth-muscle sarcoma that rarely metastasizes to the spine. Its clinical course is variable, although patients with metastatic leiomyosarcoma can experience prolonged survival as compared with patients with more aggressive metastatic tumors. The authors report their single-institution experience in the surgical treatment of patients with leiomyosarcoma metastatic to the spine. METHODS A retrospective review of the electronic medical records was performed to obtain details on clinical management and outcomes for patients who had undergone surgical intervention for metastatic leiomyosarcoma of the spine. The few articles available in the current literature on this topic were also analyzed. RESULTS Eight patients with metastatic leiomyosarcoma of the spine underwent surgical management between 2005 and 2011. Six patients (75%) had improvement in their Nurick grade. Patients who had presented with pain as a primary symptom experienced significant relief. Five patients (63%) had lesion recurrence, and 4 underwent repeat surgery at a mean of 10.2 months after their initial surgery. The mean duration of survival was 11.7 months (range 3.3-23.0 months). CONCLUSIONS Leiomyosarcoma rarely metastasizes to the spine. However, surgical intervention can relieve pain and improve neurological function. Given the potential for prolonged survival, aggressive management should be considered in well-selected patients.

Abstract
Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotally removed from the spinal canal because the spinal mass had tightly invaded the spinal cord. Because the patient's postoperative condition was poor, no adjuvant radiotherapy or chemotherapy was administered. He expired 3 months after the surgery due to relapse; the spinal and mediastinal tumor remained at the preoperative size.

Abstract
STUDY DESIGN Case report. OBJECTIVE To describe a case presented as osteolytic lesions involving 2 inconsecutive lumbar, which was pathologically proved to be of smooth muscular origin. SUMMARY OF BACKGROUND DATA Smooth muscle tumor of uncertain malignant potential (STUMP) could be diagnosed when the neoplasm showed some malignant behavior, whereas its histologic image revealed very low malignance. A 47-year-old woman presented with low back pain and numbness of the left lower extremity attributable to osteolytic lesions in the second and fourth lumbar vertebral bodies, which was subsequently diagnosed as STUMP. A benign metastasizing leiomyoma was highly suspected. METHODS Clinical, pathologic, and radiologic characters of the patient with STUMP confined within the lumbar spine were retrospectively reviewed. A mini review was also conducted. RESULTS We describe the first spine-confined case of STUMP. CONCLUSION Significant new information in the growing literature of this rare and newly identified diagnosis has addressed the need for orthopedists to consider the STUMP diagnosis.

Abstract
STUDY DESIGN A primary leiomyosarcoma located on the left side of the C2 is reported. Left-sided partial spondylectomy and anterior reconstruction with posterior stabilization was performed by a two-staged operation. OBJECTIVE To emphasize the occurrence of primary leiomyosarcoma and the importance of proper stabilization in the upper cervical spine. SUMMARY OF BACKGROUND DATA Leiomyosarcoma is a rare malignant neoplasm of the bone and the primary leiomyosarcoma of the spine is extremely rare. Radical tumor excision is the goal in case of vertebral leiomyosarcoma, but to both gain surgical access to the upper cervical spine and obtain anterior reconstruction is challenging. METHODS Leiomyosarcoma of the C2 in a 25-year-old woman with mild neurologic deficits is reported. A left-sided partial spondylectomy of C2 was performed. The defect of the vertebral body was reconstructed by expandable titanium prosthesis, and posterior craniocervical fixation was performed by the polyaxial screws in the lateral masses and rod/plates. RESULTS The surgical margin was very small. The pathology of the tumor was reported as leiomyosarcoma. No sign of local recurrence or metastasis was evident 1 year after surgery. CONCLUSION Leiomyosarcoma, although rare, should be kept in mind as one of the possible diagnoses when a patient with an upper cervical tumor is presented and complete tumor removal must be the goal.

Abstract
Primary leiomyosarcoma of bone is a rare and a diagnostically challenging tumor entity. Over a 7-year period, we identified 8 such cases that fulfilled the diagnostic criteria in 6 men and 2 women, with age ranging from 25 to 59 years (mean, 42.7 years). All cases were noted in the lower limbs, including femur and tibia as the commonly involved bones in 4 and 3 cases, respectively. On radiography, the most consistent feature was a solitary osteolytic lesion with cortical destruction, unassociated with matrix formation. On histopathology, all cases showed spindly sarcomatous cells, mostly arranged in fascicles and whorls. Of 8 cases, 6 (75%) were of high grade. Prominent vasculature was noted in 5 cases. Two cases displayed focal mineralization, including calcification and heterotropic woven bone formation in 1 case each, but lacked malignant osteoid or chondroid matrix. One case showed osteoclast-like giant cells. On immunohistochemistry, smooth muscle actin was diffusely positive in all cases (100%), desmin was positive in 6 (75%) of 8 cases, and h-caldesmon was positive in 5 (83.3%) of 6 cases. Five cases underwent surgery, including 3 amputations and 2 wide excisions. One case underwent chemotherapy. On follow-up, 5 cases developed metastasis, including 1 case with another, who died within 17 and 5 months. Leiomyosarcoma of bone is uncommon and diagnostically challenging. An index of suspicion is necessary for this diagnosis, especially in cases of lytic, destructive bone lesions, unassociated with matrix production, that show spindly sarcomatous cells on histopathology. Immunohistochemical analysis, including an optimum panel formed by smooth muscle actin (diffuse positivity), desmin, and h-caldesmon, is necessary for substantiating this diagnosis. Surgery forms the treatment mainstay. The prognosis appears to be dismal.

Abstract
Object
Sarcomas of the spine are a challenging problem due to their frequent and extensive involvement of multiple spinal segments and high recurrence rates. Gross-total resection to negative margins, with preservation of neurological function and palliation of pain, is the surgical goal and may be achieved using either intralesional resection or en bloc excision. The authors report outcomes of surgery for primary and metastatic sarcomas of the mobile spine in a large patient series.
Methods
A retrospective review of patients undergoing resection for sarcomas of the mobile spine between 1993 and 2005 was undertaken. Sarcomas were classified by histology study results and as either primary or metastatic. Details of the surgical approach, levels of involvement, and operative complications were recorded. Outcome measures included neurological function, palliation of pain, local recurrence, and overall survival.
Results
Eighty patients underwent 110 resections of either primary or metastatic sarcomas of the mobile spine. Twenty-nine lesions were primary sarcomas (36%) and 51 were metastatic sarcomas (64%). Intralesional resections were performed in 98 surgeries (89%) and en bloc resections were performed in 12 (11%). Median survival from surgery for all patients was 20.6 months. Median survival for patients with a primary sarcoma of the spine was 40.2 months and was 17.3 months for patients with a metastatic sarcoma. Predictors of improved survival included a chondrosarcoma histological type and a better preoperative functional status, whereas osteosarcoma and a high-grade tumor were negative influences on survival. Multivariate analysis showed that only a high-grade tumor was an independent predictor of shorter overall survival. American Spinal Injury Association scale grades were maintained or improved in 97% of patients postoperatively, and there was a significant decrease in pain scores postoperatively. No significant differences in survival or local recurrence rates between intralesional or en bloc resections for either primary or metastatic spine sarcomas were found.
Conclusions
Surgery for primary or metastatic sarcoma of the spine is associated with an improvement in neurological function and palliation of pain. The results of this study show a significant difference in patient survival for primary versus metastatic spine sarcomas. The results do not show a statistically significant benefit in survival or local recurrence rates for en bloc versus intralesional resections for either metastatic or primary sarcomas of the spine, but this may be due to the small number of patients undergoing en bloc resections.

Abstract
✓A primary paraspinal leiomyosarcoma invading the spine is an exceedingly rare neoplasm that may clinically mimic a schwannoma. The authors report a case involving a 45-year-old man with a primary leiomyosarcoma of the cervical paraspinal musculature that invaded the spinal canal at C1–2 and subsequently metastasized to the lungs and pancreas. Aggressive treatment consisting of resection of the primary tumor, adjunctive radiation therapy and chemotherapy, and surgical debulking of metastatic disease resulted in local tumor control at the primary site and long-term survival of the patient.

Abstract
STUDY DESIGN Marginal resection of a paraspinal tumor in the thoracic vertebra was performed. OBJECTIVE To document a very rare pathology for a paraspinal tumor. SUMMARY OF BACKGROUND DATA Primary leiomyosarcoma of the spine or paravertebral space is extremely rare. A case of a patient who was operated on for a mass in the spinal canal and whose pathology was reported to be leiomyosarcoma is presented. METHODS Marginal resection of the paravertebral mass was performed. RESULTS The pathology of the tumor was reported as leiomyosarcoma. CONCLUSION Leiomyosarcomas may develop at any site where smooth muscle cells are present. However, primary leiomyosarcoma of the spine or paravertebral space is extremely rare. Leiomyosarcoma, although rare, should be kept in mind as one of the possible diagnoses when a patient with a paraspinal tumor is presented.

Abstract
STUDY DESIGN A primary leiomyosarcoma in the L2 vertebral body without any neurologic deficit is reported. The radiologic diagnosis was a metastasis, and the histologic diagnosis was confirmed by transpedicular needle biopsy. OBJECTIVE To emphasize the occurrence of primary leiomyosarcoma in the lumbar spine. SUMMARY OF BACKGROUND DATA Leiomyosarcoma is a rare malignant neoplasm of the bone, and only one report of the primary spinal tumor exists. In the case of leiomyosarcoma of the bone, metastasis, most commonly of the uterus or gastrointestinal tract, must be carefully ruled out before the diagnosis of primary leiomyosarcoma in the bone is confirmed. METHODS Leiomyosarcoma of the second lumbar vertebra in a 47-year-old woman with no neurologic deficit is reported. Imaging findings indicated a nonspecific high-grade lesion. A total spondylectomy of L2 with en bloc excision of the lower half of L1 and the upper third of L3 vertebral bodies was performed after preoperative radiation therapy. The defect of the vertebral body was reconstructed by titanium mesh cage, and T11 to S1 vertebrae were instrumented by the pedicle screw and rod system. RESULTS The surgical margin was marginal. Histologically, the tumor cells were elongated, with abundant cytoplasm and cigar-shaped nuclei, showing proliferation in fascicles and bundles. No sign of local recurrence or metastasis was evident 2 years and 1 month after surgery. CONCLUSIONS Leiomyosarcoma should be included in the differential diagnosis of spindle cell tumor of the spine, and it should be confirmed or excluded by immunohistochemical and/or ultrastructural studies. If the expected surgical margin is definitive, a total en bloc spondylectomy should be performed.

Abstract
OBJECTIVE Surgery plays an important role in achieving local tumor control and cure for primary and metastatic tumors of the spine. As has been established with regard to sarcomas at extraspinal sites, these goals may best be achieved by en bloc resection with negative histological margins. Unfortunately, sarcomas of the spine often present with tumor patterns that are amenable only to intralesional resection, if neurological preservation is a priority. This study is a retrospective analysis of the long-term outcomes of patients who had operations for sarcomas of the spine using modern surgical approaches, intralesional resections, and spinal instrumentation. METHODS Between 1985 and 1997, 59 patients had spinal operations for sarcoma involving the extrasacral spine. Data regarding tumor histology, grade, surgical indications, patterns of spinal tumor involvement, and neurological and functional outcomes were reviewed at presentation and at tumor recurrence. RESULTS Thirty-five patients underwent a single operation, and 24 patients required reoperation for locally recurrent tumors. At presentation, only nine patients (15%) had tumors that were amenable to marginal or wide resections. Functional outcomes after initial spinal surgery and after operations performed at first tumor recurrence showed that 95% of patients had maintained or regained ambulation. Intradural extension of tumor was seen in 5 of 12 patients who had three or more operations for locally recurrent disease. The median survival from first spine operation was 18 months, and the median event-free interval between the first and second spine operations was 13 months. CONCLUSION Surgery for sarcoma of the spine is useful for maintaining or improving neurological and functional outcomes, but local tumor recurrences are common. Because of the anatomy of the tumor at presentation and concern for neurological preservation, few patients are candidates for marginal or wide resections.

Abstract
Primary leiomyosarcoma of bone is very rare. Most of reported cases were osteolytic. We report a primary leiomyosarcoma arising from the neck of the femur of a 43-year-old woman who had no remarkable abnormalities on plain radiographs. Magnetic resonance imaging (MRI) clearly depicted the lesion. Biopsy revealed it leiomyosarcoma. Gynecological and gastrointestinal examinations ruled out metastatic leiomyosarcoma. Wide excision of the tumor was performed and followed by endoprosthetic replacement of the proximal femur. Microscopic examination revealed tumor cells infiltrating into the intertrabecular space.

Abstract
Leiomyosarcomas (LMSs) of the central nervous system are extremely rare; however, they are becoming more prevalent in immunocompromised patients. The authors present the cases of two patients with acquired immunodeficiency syndrome: one with LMS of the thoracic vertebral body and the other with LMS originating from the region of the cavernous sinus. The epidemiological and histological characteristics of LMS and its association with latent Epstein-Barr virus are discussed, as well as the treatments for this neoplasm.

Abstract
Leiomyosarcoma of bone is a rare tumor in an unusual location. Previous analysis of this entity mostly involved small numbers of cases with limited follow-up. Thirty-three patients with leiomyosarcoma of bone between 1977 and 1996 were studied, and the histologic appearance and grade were correlated with subsequent treatment and clinical behavior. To be included in this study the tumor had to be intraosseous, with other primary sites of origin clinically excluded. Also, most of the sarcomatous tissue (> or =70%) had to be of intramedullary location with only limited extraosseous extension. The patient's age at diagnosis ranged from 13 to 77 years (average 44.4). The gender distribution was equal. The long bones were preferentially affected (64%), with the lower extremity, around the knee joint, predominantly involved. Five patients (15%) developed postradiation leiomyosarcomas. The histologic analysis showed that the osseous leiomyosarcomas are most commonly of the classic type, followed by the epithelioid, myxoid, and pleomorphic variants. Immunoreactivity for smooth muscle markers (smooth muscle actin, common muscle actin, desmin) was positive in all tumors, and ultrastructural confirmation was obtained in 21% of cases. All sarcomas were histologically graded, which accurately reflected the subsequent prognosis. Seventy-five percent of the lesions were high-grade and the rest low-grade. The histologic grade of the tumors correlated with both the recurrence as well as the metastatic rates and together with the clinicopathologic stage of disease represented the cornerstone on which prudent therapy should be based.

Abstract
A 35-year-old man infected with human immunodeficiency virus presented with cervical myelopathy of 2 months duration. Clinical and radiographic evaluation revealed a discrete, subdural mass at C-6. At surgery, the mass proved to have a dural attachment and thus clinically, radiographically, and grossly, it resembled meningioma. Histopathological analysis revealed a leiomyosarcoma that stained diffusely for muscle-specific actin. Electron microscopy revealed basal lamina surrounding the tumor cells and intracytoplasmic bundles of myofilaments. Epstein-Barr virus (EBV) was demonstrated within tumor cell nuclei by in situ hybridization for EBER1 messenger RNA and immunohistochemical staining for EBNA2 protein. Epstein-Barr virus latent membrane protein (LMP1) was not detected. This is the first documentation of an EBV-associated smooth-muscle tumor of the dura, and the first demonstration that tumors in this location contain EBV in an unusual form of latency not seen in lymphoid cell lines. With increasing numbers of individuals being afflicted with long-term immunosuppression, EBV-associated dural leiomyoma and leiomyosarcoma may be encountered more frequently in the future.
