A bone tumor composed of cellular spindle-cell stroma containing scattered multinucleated giant cells resembling osteoclasts. The tumors range from benign to frankly malignant lesions. The tumor occurs most frequently in an end of a long tubular bone in young adults. (From Dorland, 27th ed; Stedman, 25th ed)
Tumors of bone tissue or synovial or other soft tissue characterized by the presence of giant cells. The most common are giant cell tumor of tendon sheath and GIANT CELL TUMOR OF BONE.
A scraping, usually of the interior of a cavity or tract, for removal of new growth or other abnormal tissue, or to obtain material for tissue diagnosis. It is performed with a curet (curette), a spoon-shaped instrument designed for that purpose. (From Stedman, 25th ed & Dorland, 27th ed)
Tumors or cancer located in bone tissue or specific BONES.
A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
A cartilage-capped benign tumor that often appears as a stalk on the surface of bone. It is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. Osteochondroma is the most common of benign bone tumors.
Multinucleated masses produced by the fusion of many cells; often associated with viral infections. In AIDS, they are induced when the envelope glycoprotein of the HIV virus binds to the CD4 antigen of uninfected neighboring T4 cells. The resulting syncytium leads to cell death and thus may account for the cytopathic effect of the virus.

Giant cell tumor of the thoracic spine simulating mediastinal neoplasm. (1/180)

A case of giant cell tumor of the thoracic spine simulating mediastinal neoplasm was identified on plain films, CT scans, MR images, and with scintigraphy. CT showed a hypervascular soft-tissue mass with shell-like calcification in the right upper mediastinum. MR imaging showed a collapse of the T1 vertebral body and a mass extending to the mediastinum. The mass had a low signal on T1-weighted MR images and a predominantly high signal on T2-weighted images with heterogeneity. Technetium-99m methylene diphosphonate bone scintigraphy showed intense uptake in both the T1 and marginal parts of the mediastinal mass. There was no accumulation of gallium-67 citrate, but 18-fluorine fluorodeoxyglucose positron emission tomography showed marked uptake. The variation in these imaging findings played an important role in the differential diagnosis of this uncommon mediastinal mass.  (+info)

Association of HLA-DRB1 alleles with giant cell tumour of bone. (2/180)

AIM: To examine the possible influence of the MHC class II antigens alleles in the formation of the multinucleate aggressive giant cell tumour of bone. METHODS: HLA class II antigen alleles were investigated in eight white patients from north east England with confirmed diagnosis of giant cell tumour of bone. All had locally aggressive, immunophenotypically HLA-DR negative giant cell tumours. RESULTS: Five of the eight patients were found to be positive for HLA-DRB1*0801/3, the distribution of this allele in healthy white controls being quite low (2%). All but one of the patients possessing DRB1*080 also expressed DRB1*070. CONCLUSIONS: HLA-DRB1*080 is pre-dominant in patients with immunophenotypic HLA-DR negative giant cell tumour of bone; individuals with the genotype 070/080 are at particularly high risk of developing giant cell tumour of bone.  (+info)

Synovial tissue in rheumatoid arthritis is a source of osteoclast differentiation factor. (3/180)

OBJECTIVE: Osteoclast differentiation factor (ODF; also known as osteoprotegerin ligand, receptor activator of nuclear factor kappaB ligand, and tumor necrosis factor-related activation-induced cytokine) is a recently described cytokine known to be critical in inducing the differentiation of cells of the monocyte/macrophage lineage into osteoclasts. The role of osteoclasts in bone erosion in rheumatoid arthritis (RA) has been demonstrated, but the exact mechanisms involved in the formation and activation of osteoclasts in RA are not known. These studies address the potential role of ODF and the bone and marrow microenvironment in the pathogenesis of osteoclast-mediated bone erosion in RA. METHODS: Tissue sections from the bone-pannus interface at sites of bone erosion were examined for the presence of osteoclast precursors by the colocalization of messenger RNA (mRNA) for tartrate-resistant acid phosphatase (TRAP) and cathepsin K in mononuclear cells. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to identify mRNA for ODF in synovial tissues, adherent synovial fibroblasts, and activated T lymphocytes derived from patients with RA. RESULTS: Multinucleated cells expressing both TRAP and cathepsin K mRNA were identified in bone resorption lacunae in areas of pannus invasion into bone in RA patients. In addition, mononuclear cells expressing both TRAP and cathepsin K mRNA (preosteoclasts) were identified in bone marrow in and adjacent to areas of pannus invasion in RA erosions. ODF mRNA was detected by RT-PCR in whole synovial tissues from patients with RA but not in normal synovial tissues. In addition, ODF mRNA was detected in cultured adherent synovial fibroblasts and in activated T lymphocytes derived from RA synovial tissue, which were expanded by exposure to anti-CD3. CONCLUSION: TRAP-positive, cathepsin K-positive osteoclast precursor cells are identified in areas of pannus invasion into bone in RA. ODF is expressed by both synovial fibroblasts and by activated T lymphocytes derived from synovial tissues from patients with RA. These synovial cells may contribute directly to the expansion of osteoclast precursors and to the formation and activation of osteoclasts at sites of bone erosion in RA.  (+info)

Gene expression of osteoprotegerin ligand, osteoprotegerin, and receptor activator of NF-kappaB in giant cell tumor of bone: possible involvement in tumor cell-induced osteoclast-like cell formation. (4/180)

Giant cell tumor of bone (GCT) is a rare primary osteolytic tumor of bone that is characterized by massive tissue destruction at the epiphysis of long bones. There is no evidence that tumor cells themselves are capable of bone destruction; instead, it appears that the tumor cells of GCT act by promoting osteoclastogenesis and, as a consequence, osteoclastic bone resorption. However, the mechanism by which this is achieved is not understood. Here we attempted to determine whether osteoprotegerin ligand (OPGL), the factor that is necessary and essential for osteoclastogenesis, is involved in tumor cell-recruited osteoclast-like giant cell formation in GCT. Using fluorescence in situ hybridization, we sought to determine mRNA expression of OPGL, its receptor RANK, and its decoy receptor OPG in three major cell types of GCT. We demonstrated that OPG mRNA was expressed in all three cell types of GCT, OPGL transcripts were mainly detected in spindle-shaped stromal-like tumor cells, whereas RANK was expressed only in macrophage-like mononuclear cells and multinuclear osteoclast-like giant cells. By semiquantitative RT-PCR, we also showed that the level of OPGL mRNA in GCT is much higher than that in normal bone and osteogenic osteosarcoma. In contrast, a similar level of OPG transcripts was detected in these three kinds of tissues, and RANK mRNA was detectable only in GCT tissues. We have further examined the regulation of gene expression of OPGL and OPG in tumor cells in response to osteotropic hormones. Administration of 1,25(OH)(2)D(3) and dexamethasone resulted in maximum up-regulation of OPGL level and down-regulation of OPG level in cultured GCT stromal-like tumor cells and the mouse bone marrow-derived ST-2 stromal cell line. Furthermore, we have shown that tumor cells of GCT induce differentiation of RANK-expressing myeloid RAW(264.7) cells into osteoclast-like cells in the presence of 1,25(OH)(2)D(3) and dexamethasone. Our findings suggest that OPGL is involved in the tumor cell-induced osteoclast-like cell formation in GCT. The ratio of OPGL/OPG by tumor cells may contribute to the degree of osteoclastogenesis and bone resorption.  (+info)

Distal fibular giant cell tumour. (5/180)

The prognostic significance of DNA cytophotometry and proliferation index (Ki-67) in giant cell tumors of bone. (6/180)

We studied DNA ploidy by smear cytophotometry and proliferation activity by Ki-67 MIB immunohistochemistry in 69 primary and recurrent giant cell tumors (GCT) from 50 randomly selected patients. The obtained results were evaluated with comparisons made to the available clinical data. From the 46 primary tumors 63% showed diploidy and 37% aneuploidy. A significantly (P=0.026) higher recurrence rate (64%) was observed in aneuploid than in diploid tumors (31%). In the course of the recurrences, both the ratio of aneuploid tumors as well as the proliferation index of the tumors increased, though the degree of the latter was non-significant. Aneuploidy did not mean an unambiguous tendency towards malignant transformation; however, a close follow-up of recurrent aneuploid tumors, and wide excision of the recurrence instead of intralesional curettage are the recommended procedures. The DNA cytophotometry and proliferation index of GCTs--as compared to other histologic examinations--are of prognostic value in the evaluation of the recurrence potential of the GCTs.  (+info)

The quadriceps myocutaneous flap for operation on the distal femur. (7/180)

We describe a U-shaped approach to the distal femur which, having divided the extensor mechanism and elevated the entire quadriceps muscle, gives excellent exposure and allows a number of reconstructive options. It was used in 14 patients, 13 of whom were followed up for a mean of 3.5 years (1 to 11). There was no case of flap necrosis, and complications related to the reconstruction were acceptable.  (+info)

Giant cell tumour of talar body. (8/180)

Giant cell tumour (osteoclastoma) of talar bone is a rare entity and is seen more commonly in the third decade of life. We report this disease entity in a 17-years-old girl. The patient presented with painful swelling of the left ankle with an osteolytic lesion in the talus on conventional radiographs. Intralesional curettage and autologous bone grafting was performed following which patient's pain and swelling disappeared. Complete range of movement at the ankle joint was regained with minimal restriction at the subtalar joint. There is no evidence of relapse at six months follow up.  (+info)

Although it is the treatment of choice for these tumours, wide resection creates a problem for the reconstruction of large bone gaps. We describe our results after resection arthrodesis of such tumours using the technique of bone transport over a long intramedullary nail in 27 patients. This is the first and largest study of its kind in the management of giant cell tumours in the literature. All our patients fared well with this mode of treatment, and none had recurrence or major complications..

Giant cell tumors of the bone are uncommon bone tumors which represent around 4-5% of primary bone tumors and 18% of all benign bone lesions. They are interesting in the fact that their classic radiographic appearance is easily identifiable. Giant cell tumors can either be benign or malignant, although the majority of them are benign. Radiographically, benign versus malignant tumors are difficult to distinguish. In most patients, the tumor has an indolent course, but repeated local recurrence of the tumor does happen. Approximately 5% of giant cell tumors are defined as malignant. Malignancy usually occurs as the result of malignant transformation after radiation therapy. These tumors are slightly more common in females, with 50-57% of cases occurring in females. The general age range for giant cell tumors is 20-40 years old. Approximately 85% of tumors occur in the long bones, namely the distal femur, proximal tibia, proximal humerus, and distal radius. Another location typical of giant cell ...
Understanding Giant cell tumor (GCT) of bone has been described as the most challenging benign bone tumors. The majority of these tumors, classically, are involved in the epiphysis of long bones. Although this disorder is benign, GCTs show a tendency of bone destruction, local recurrence and, occasionally, pulmonary metastasis. But axillary lymohnode metastasis is very very rare. Herein, we present an extremely rare case of axillary mets even after below elbow amputation in a case of recurrent giant cell tumor in a 45 yers male residing at Kolkat,.West Bengal. We treat him by radical axillary lumph node dissection.Lymph node histopatho;ogical report shows Tartrate-resistant acid phosphatase (TRAP) activity.. ...

AU - Demulder, A.. AU - Nishihara, T.. AU - Williams, R.. AU - Roodman, G. D.. PY - 1992/11. Y1 - 1992/11. N2 - Interleukin-6 (IL-6) is a multifunctional cytokine whose role in osteoclastic bone resorption has not been clearly defined. Therefore, we have used giant cells, which express many features of osteoclasts, from giant cell tumors of bone as a model to examine the role that IL-6 may play in human osteoclastic bone resorption. We found that conditioned medium from 24-h cultures of highly purified giant cells (106/ml) contained large amounts of IL-6 (37.9 ± 8.8 ng/ml), similar to the amount of IL-6 produced by tumor stromal cells (29.8 ± 11.5 ng/ ml). Giant cells and stromal cells from giant cell tumors expressed IL- 6 mRNA, as indicated by polymerase chain reaction analysis and in situ ...
A giant cell tumor is one that is made up of a large number of benign (noncancerous) cells that form an aggressive tumor, usually near the end of the bone near a joint. The location of a giant cell tumor is often in the knee, but can also involve the bones of the arms and the legs, or the flat bones such as the sternum (breastbone) or pelvis.. Giant cell tumors most often occur in young adults when skeletal bone growth is complete. Most occur in the long bones of the legs and arms.. ...
MAYET, Z; NOBLE, T and MAGOBOTHA, SKM. Giant cell tumour of the tendon sheath (GCT-TS) in the foot: A case report. SA orthop. j. [online]. 2014, vol.13, n.1, pp.39-43. ISSN 2309-8309.. Giant cell tumour of the tendon sheath (GCT-TS) has been described as the most common tumour of the hand following ganglion cysts. In contrast it is much rarer in the foot, with only 3-10% of GCT-TS being described in the foot. A PubMed and Medline search of the topic has revealed two case series and 12 case studies. It is therefore an uncommon condition, but should be considered as part of a differential diagnosis for a mass in the foot. We present the case of a 42-year-old male who presented with a large painful mass in in the third web space of his left foot, which was 7 cm in length in vivo. It crossed the anatomical compartments of the forefoot and midfoot. Our case report showed the typical findings of a GCT-TS. Along with this we also present a review of the literature..

While over 90% of GCTB presents histone 3.3 variants exclusively in the H3F3A gene, chondroblastoma is mutated mainly in H3F3B. In this study we examined a series of giant cell rich primary bone tumors, aiming to evaluate the possible diagnostic role of histone 3.3 mutations in the differential diagnosis between GCTB and giant cell rich sarcomas. Sixteen cases of non-metastatic GCTB, 9 GCTB with lung metastases, and 35 giant ...
The U.S. Food and Drug Administration (FDA) has expanded the approved use of Xgeva® (denosumab) to include the treatment of adults and some adolescents with giant cell tumor of the bone (GCTB).. Giant cell tumor of bone (GCTB) is a rare, aggressive, benign osteolytic tumor in which bone destruction is mediated by a protein known as the RANK ligand. This protein regulates the activity of osteoclasts (cells that break down bone). GCTB typically affects younger adults between the ages of 20 to 40. Historically, the only treatment option for patients with GCTB has been surgery; however, patients who undergo surgery often have recurrent disease or devastating consequences, such as amputation. Whats more-about 25 to 30 percent of patients with GCTB have to undergo joint replacements.. Xgeva is a type of targeted drug known as a monoclonal antibody. The drug targets the RANK ligand, thereby inhibiting bone destruction and potentially eliminating giant cells. Xgeva was approved in 2010 for the ...
Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal cells and the presence of many multi- nucleated giant cells with homogenous distribution. There is no widely held consensus regarding the ideal treatment method selection. There are advocates of varying surgical techniques ranging from intra-lesional curettage to wide resection. As most giant cell tumors are benign and are located near a joint in young adults, several authors favor an intralesional approach that preserves anatomy of bone in lieu of resection. Although GCT is classified as a benign lesion, few patients develop progressive lung metastases with poor outcomes. Treatment is mainly surgical. Options of

Abstract Giant cell tumours of the sacrum pose a unique therapeutic challenge due to the inaccessibility of the tumour, significant intra-operative blood loss from extensive vascularity, high rate of local recurrence with conservative surgery, and loss of neurological function and mechanical instability with en-bloc excision. We present a case where successful outcome was achieved by tailoring treatment in consideration of the above issues. A 28 year old male diagnosed on biopsy to have giant cell tumour of the sacrum presented to us with low-back pain, left-sided S1 radiculopathy, ankle weakness and urinary incontinence. MRI showed a tumour involving the S1 and S2 vertebral segments, breaching the posterior cortex and compressing the neural elements. An angiographic tumour embolization was performed followed by surgery through a posterior approach whereby an extended curettage was done, carefully freeing the sacral nerve roots and abrading the bone using high-speed burr. An ilio-sacro-lumbar fusion was

Giant cell tumor of bone (GCT) is a rare, aggressive non-cancerous (benign) tumor. It generally occurs in adults between the ages of 20 and 40 years. Giant cell tumor of bone is very rarely seen in children or in adults older than 65 years of age. Giant cell tumors occur in approximately one person per million per year. Giant cell tumors of bone most frequently occur around the knee joint in the lower end of the thighbone (femur) or the upper end of the shinbone (tibia). Other common locations include the wrist (lower end of the lower arm bone), the hip (upper end of the thighbone), the shoulder (upper end of the upper arm bone), and lower back (connection of the spine and pelvis). If not treated, these tumors will continue to grow and destroy bone. Surgery has proven to be the most effective treatment for giant cell tumors.. ...
There are still some debates regarding the best treatment of Giant Cell Tumor (GCT) of the sacrum. Since GCT of this location is rare, therapeutic strategies are mainly based on the treatment of GCT in other anatomic locations. The objective of this study was to evaluate the oncologic and clinical results of surgical management of sacral GCT with and without local adjuvant therapy. Medical records of 19 patients diagnosed with GCT of the sacrum, were retrospectively reviewed. Sixteen patients were treated by intralesional curettage and three patients with marginal resection. Musculoskeletal tumor society (MSTS) score was used for the evaluation of functional outcome. Prolonged pain was the most common complication after treatment. Mean Pre and post-operative pain based on visual analogue scale (VAS) was 6.1 ± 1.99 and 3.05 ± 1.64, respectively. Postoperative neurologic deficit appeared in six patients. In addition, infection occurred in five patients. One case of spinopelvic instability was also

Treatment of giant basilar aneurysms is extremely challenging, especially recurrences after previous coiling. A 20-year-old male was referred for a recurrent giant proximal basilar aneurysm 3 months after coiling, with headache, blurred vision, and brainstem compression symptoms. Angiography showed that the previously placed coils were compacted within the caudal portion of the 43 mm × 31 mm aneurysm, with spontaneous occlusion of the right vertebral artery and absence of the posterior communicating arteries. The diameter of the aneurismal neck, the afferent and efferent arteries was 6 mm, 3.5 mm and 4.1 mm, respectively. A balloon-expandable covered-stent of 3.5 mm × 10 mm was selected, matching the above 3 measurements; and deployed precisely across the aneurismal neck, immediately creating the
Methods: Criteria included 16 patients of Campanacci Grade 3 GCT in which 14 male and 2 female around aged between 20and 60 years with a mean age of 30 years underwent resection and arthrodesis of the knee for GCTs of bone involving the distal femur(n=7) or proximal tibia(n= 9).After wide resection,2 struts were fashioned from the harvested fibula of thesame side and inserted into medullary canal at the resected ends of the tibia and femur.Cancellous bone grafts were taken from thesame side of theiliac crest.Hemicylindrical graft was taken from anteriorpart of either distal femur or proximal tibia. A long intramedullary interlocking nail was inserted inretrograde fashion through piriformis fossa to distal tibia.Cancellous bone grafts[2,3]were placed transversely along the struts and circumferentially over the host-graft junctions.For other patients, long Kuntscher nail and DCP plate with K-wirewere used.Results of arthrodesis were evaluated those in which long intramedullary interlocking ...

View more ,Background: Giant cell tumors (GCTs) of the distal ulna are rare. Despite being benign, they can be locally aggressive and may recur following conventional treatment by curettage and bone grafting. Salvage reconstructive options after failed conventional treatment include Darrach resection, Suave-Kapandji procedure, hemi-arthroplasty, or total joint arthroplasty. Methods: We discuss reconstruction options for the distal radio-ulnar joint following tumor resection, and present the outcomes of a constrained distal radio-ulnar prosthesis in a 29-year-old male following resection of a distal ulna GCT. Results: Reconstruction of the distal radio-ulnar joint by a constrained prothesis yielded excellent functional outcomes following resection of a GCT of the distal ulna. Conclusions: This case demonstrates that successful oncologic and functional outcomes can be achieved by radical resection of a recurrent GCT of the distal ulna and reconstruction with a constrained total joint arthroplasty ...
Giant cell tumor (GCT) of bone is a benign aggressive tumor with features of frequent local recurrences and potential for metastasis and malignant transformation [1]. GCT is commonly seen in young adults 20-40 years of age with slight female predominance, and constitutes 5% of total primary neoplasms [2]. Giant cell tumor of bone typically presents as a solitary lytic lesion that spans the metaphyseal-epiphyseal region of long bones of adults. In approximately 1% of cases, however, it manifests as multiple synchronous or metachronous lesions in single or multiple bones. Such cases have been designated multicentric giant cell tumors and their pathogenesis is unknown.. Their clinical and radiographic differential diagnosis usually includes a variety of polyostotic skeletal lesions such as Brown tumor, Pagets disease, osteomyelitis, Non-ossifying fibroma, enchondromatosis, fibrous dysplasia, giant cell reparative granuloma, Langerhans cell histiocytosis, vascular tumor, osteosarcoma, hematopoietic ...

PY - 2012/3. Y1 - 2012/3. N2 - A 53-year-old woman presented with left mandibular area pain, trismus, and facial numbness that had persisted for 4 years. Physical examination revealed a 3×5 cm, hard, non-tender, and round mass on the left mandibular area. Computed tomography and magnetic resonance imaging revealed an expansile tumor involving the left mandibular ramus and temporomandibular joint area with bone destruction, extending to the base of middle cranial fossa and left zygomatic bone. The mass at the segment of left mandible and zygomatic bone, and base of middle cranial fossa was removed. Pathological examination of the mass revealed a giant cell tumor. The defect was reconstructed with iliac bone for the mandible and temporal bone and fascia for the cranial bone and dura. The case is ...

Introduction Currently there is no consensus if wide resection and curettage in giant cell tumor have effect on local recurrence rate in the presence of a pathological fracture. of pathological fracture treated with wide resection and curettage was 0.298% (95% Confidence interval (CI) Angiotensin II tyrosianse inhibitor 0.0669C1.329, p?=?0.97). Summary Wide resection and curettage in individuals of huge cell tumor with pathological fracture offers difference in local recurrence rates. However the presence of a Angiotensin II tyrosianse inhibitor pathological fracture should no become only influential factor in the decision making to perform wide resection or curettage. A proper planning and judicious approach is required in giant cell tumor with pathological fracture for determining the appropriate treatment method. strong class=kwd-title Keywords: Giant cell tumor, Pathological fracture, Curettage, Large resection, Regional recurrence 1.?Intro The prevalence of pathological fractures runs ...
Introduction: Giant cell tumor of the tendon sheath (GCTTS) is a benign tumor, originating from proliferation of the synovial cells of a tendon sheath. It is very rare within the pediatric population. Case Report: In this case presentation, we describe two cases of GCTTS in the hand, in a 7-year-old female and a 6-year-old male. Conclusion: GCTTS occurs very uncommonly in children. It is difficult to accurately diagnose on clinical examination and radiological investigation alone, and thorough and complete excision is important to avoid recurrence of the lesion. The two cases presented in this report help further define this condition, in terms of diagnosis and management, in the pediatric population.

Giant-cell carcinoma of the lung (GCCL) is a rare histological form of large-cell lung carcinoma, a subtype of undifferentiated lung cancer, traditionally classified within the non-small-cell lung carcinomas (NSCLC). The characteristic feature of this highly lethal malignancy is the distinctive light microscopic appearance of its extremely large cells, which are bizarre and highly pleomorphic, and which often contain more than one huge, misshapen, pleomorphic nucleus (syncytia), which result from cell fusion. Although it is common in the lung cancer literature to refer to histologically mixed tumors containing significant numbers of malignant giant cells as giant-cell carcinomas, technically a diagnosis of giant-cell carcinoma should be limited strictly to neoplasms containing only malignant giant cells (i.e. pure giant-cell carcinoma). Aside from the great heterogeneity seen in lung cancers (especially those occurring among tobacco smokers), the considerable variability in diagnostic ...
Kai Wang and Bin Zhu contributed equally to this study and shared the first authorship DOI : 10.5137/1019-5149.JTN.9594-13.1 Three patients with spinal primary diffuse-type tenosynovial giant cell tumor (DTGCT) received surgical treatment in our department between 2002 and 2012. All 3 patients were female and aged 23, 33, and 44 years. The mean time from symptom onset to diagnosis was 17 months (range, 5-24 months). One case involved the C1 right lateral mass and C2 vertebral body, the second involved the C1-2 left lateral masses and C2 vertebral body, and the third involved the C5-7 left lateral mass and C6 vertebral body. All patients underwent computed tomographyguided biopsy to confirm the diagnosis of tenosynovial giant cell tumor. Gross total resection was achieved in all patients, including 2 piecemeal resections and 1 en-bloc resection. The mean follow-up time was 6 years (range, 1-11 years), and there was no sign of recurrence in the patients. Seventy cases have been identified so far ...

Giant cell tumor (GCT) is a benign, locally aggressive tumor that rarely occurs in the spine. They usually occur in patients between 20 and 40 years of age; some patients with GCT present in hospital with pregnancy. The management of these patients can be challenging. The current study reports a case of GCT located in the sixth thoracic vertebra of a 31-year-old female at 34 weeks of gestation. An osteolytic lesion, 3.5 cm × 3.5 cm in diameter, was identified on CT. An MRI test of the lesion revealed a soft tissue mass involving the T 6-7 vertebrae, extending to the right pedicle of the T 6 vertebra and causing significant spinal cord compression ...
