INTRODUCTION: Giant cell tumor (GCT) or osteoclastoma is an osteolytic, mostly benign but locally aggressive tumor occurring in young adults at the epiphysis. Area of predilection is mainly long bones (85-90%). 4% of GCT are also found in iliac bone, spine and only 2% in hand (of which GCT phalanges are more common than metacarpal). GCT of metatarsal is a very rare occurrence with very few cases being reported so far. We report a case of GCT 1(st) metatarsal in a 40-year-old male which is a very rare entity...

Giant cell tumor of bone (GCTB) is a locally aggressive subarticular tumor. Having recently reported that H3.3 G34W mutations are characteristic of this tumor type, we have now investigated the sensitivity and specificity of the anti-histone H3.3 G34W rabbit monoclonal antibody in a wide variety of tumors including histologic mimics of GCTB to assess its value as a diagnostic marker. We also determined the incidence of H3.3 G34 mutations in primary malignant bone tumors as assessed by genotype and H3.3 G34W immunostaining...

Case A 90-year-old Chinese man presented to our hospital with a one-year history of a large neoplasm on his right cheek (figure). The patient did not have subjective symptoms but emitted an obvious stench. However, the patient has significant embarrassment and difficult on social interaction due to abnormal appearance and foul smell from lesion. A clinical examination showed that the tumor size was 7cm * 6.5cm * 1.5cm. An X-ray examination showed that the deep tumor was not associated with any bone destruction...

BACKGROUND: Histone 3.3 (H3.3) hotspot mutations in bone tumors occur in the vast majority of giant cell tumors of bone (GCTBs; 96%), chondroblastomas (95%) and in a few cases of osteosarcomas. However, clinical presentation, histopathological features, and additional molecular characteristics of H3.3 mutant osteosarcomas are largely unknown. METHODS: In this multicentre, retrospective study, a total of 106 conventional high-grade osteosarcomas, across all age groups were re-examined for hotspot mutations in the H3...

A 7-year-old cat was referred with pelvic limb ataxia. Radiography and CT revealed bone resorption of the L1 vertebral arch, and myelography identified a compressive extradural lesion. The mass was surgically removed and histopathologically diagnosed as giant cell osteosarcoma. Three years later, the recurrent tumor resection and vertebral fixation were performed. Six months later, vertebrectomy was performed to radically excise the recurrent mass and a titanium spinal cage was placed. The cat is alive approximately 5 years after the first surgery...

Although Central Giant Cell Granuloma (CGCG) is a benign tumor of the jaw and aneurysmal bone cyst seen in children, its aggressive behavior causes extensive loss of hard tissue requiring wide excision and extensive rehabilitation. We report a rare case of concomitant CGCG and aneurysmal bone cyst in a two-year-old male child, involving the coronoid and condylar process. Young age, large tumor, its aggressive nature, and future growth of orofacial region pose a significant challenge in the management of such conditions...

AIMS: Giant cell tumor of soft tissue (GCT-ST) is a primary soft tissue neoplasm histologically similar to GCT of bone (GCT-B). Recently, it has been reported that >90% of GCT-B have a driver mutation in H3F3A gene. Since the relationship between GCT-ST and GCT-B is unclear, we compared a series of GCT-ST and GCT-B for the presence of H3F3A mutations and for several immunophenotypic markers. METHODS AND RESULTS: Eight cases of GCT-ST were retrieved from our institutional archives...

Giant cell tumor (GCT) of the craniofacial bones has been reported but they are not common. This tumor occurs more often in women than in men and predominantly affects patients around the third to fifth decade of life. GCTs are generally benign but can be locally aggressive as well. We report a case of GCT involving the temporomandibular joint (TMJ), which was initially thought to be temporomandibular disorder (TMD). A 22-year-old female presented with swelling and pain over the right temporal region for 18 months associated with jaw locking and clicking sounds...

Giant cell tumor of bone (GCT), which frequently occurs in the patients' spine, is relatively prevalent in Chinese population. A group of GCT invades into vessels and appears to be circulating tumor cells (CTCs) responsible for the distal metastasis of the primary tumor. So far the cell surface markers of GCT have not been determined. In the current study, we aimed to identify a novel CTC marker with higher specificity in GCT. TRAIL-R1+ cells were purified from GCT cell lines. The TRAIL-R1+ cells were compared with total GCT cells for tumor sphere formation, chemo-resistance, tumor formation in nude mice, and frequency of developing distal metastases...

Aneurysmal bone cysts (ABCs) are benign bony lesions frequently accompanied by multiple cystic lesions and aggressive bone destruction. They are relatively rare lesions, representing only 1% of bone tumors. The pathogenesis of ABCs has yet to be elucidated. In the present study, a series of 22 cases of primary and secondary ABC from patients treated in Department of Orthopedic Surgery, Kagoshima University Hospital (Kagoshima, Japan) from 2001-2015 were retrospectively analyzed. The average age at the time of diagnosis of primary ABC was 17...

Paget's disease of the bone may predispose the development of malignant bone tumors such as osteosarcoma. Giant cell tumor (GCT) as a consequence of Paget's disease is rare. Bone GCT is characterized by rapid growth, the destruction of bone, extension to the surrounding soft tissue and abnormal bone turnover caused by an abnormality of the receptor activator of nuclear factor-κB (RANK)-RANK ligand (RANKL) pathway. Denosumab is a RANK-RANKL inhibitor, which is used to treat osteoporosis and bone GCT. In the current study, a 60-year-old male presented with severe pain located between the right thigh and the knee...

BACKGROUND: Benign bone lesions are much more common than malignant lesions. Some benign bone tumors have a characteristic and typical radiographic appearance, while others are more challenging. Therapy of benign bone tumors differs greatly. While the majority of benign bone tumors do not require surgical therapy, other specific lesions, e. g. aneurysmal bone cysts or giant cell tumors (GCT) of the bone require surgery due to their locally aggressive behavior. DIAGNOSTICS: The major challenge for the radiologist and/or pathologist is the differentiation between a benign and low-grade malignant lesion (e...

Giant cell tumor of bone (GCTB) is commonly treated with surgery; however, surgery of GCTB in the sacrum may be challenging due to the associated risk. A conservative approach may be selective arterial embolization or zoledronic acid (ZOL) treatment; however, there are currently no studies investigating the efficacy of combining these two treatments. Denosumab may also be used; however, to the best of our knowledge, there are no reports of a stepwise approach for the use of all three treatments in a single patient...

Pulmonary metastasis of benign giant cell tumor of bone is very rare, and its biological behavior is difficult to predict. In the present study, we analyzed the clinical characteristics of and related risk factors for pulmonary metastasis of this tumor. Forty-six patients with lung metastasis were analyzed. In total, 60.9% of the primary tumors were located around the knee joint. The Campanacci stage of all tumors was stage 3. Surgery of the primary tumor included curettage in 37 patients, resection in 8, and amputation in 1...

The aim of this study was to evaluate the in vivo bone regeneration capability of alginate (AL), AL/hydroxyapatite (HA), and AL/HA/silk fibroin (SF) composites. Forty Sprague Dawley rats were used for the animal experiments. Central calvarial bone (diameter: 8.0 mm) defects were grafted with AL, AL/HA, or AL/HA/SF. New bone formation was evaluated by histomorphometric analysis. To demonstrate the immunocompatibility of each group, the level of tumor necrosis factor (TNF)-α expression was studied by immunohistochemistry (IHC) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) at eight weeks post implantation...

Giant-cell tumor (GCT) involving the skull base is rare. Sphenoid bone is the most commonly involved bone followed by petrous temporal bone. Histopathology and radiological features of these lesions are similar to GCT involving bone elsewhere. Unlike other sites, skull base is not an ideal site for the radical surgery. Hence adjuvant treatment has pivotal role. Radiation therapy with intensity-modulated radiation therapy, stereotactic radiosurgery or chemotherapy with adriamycin are promising as described in some case reports...

This report describes the case of a 42-year-old woman who consulted with a maxillofacial specialist for pain and an exophytic lesion in the maxilla. Biopsy examination disclosed a bone cyst with abundant giant cells, and head and neck computed tomography was performed. A diagnosis of brown tumor in the maxilla and mandible was made, and primary hyperparathyroidism (parathyroid adenoma) was determined as the origin of the bone lesions. The patient underwent a left superior parathyroidectomy, which resolved the hormonal disorder (as determined by normal calcium and parathyroid hormone levels) and the brown tumors, which appeared to have mineralized at 1-year follow-up computed tomography...

PURPOSE: Denosumab, a novel monoclonal antibody that targets the receptor activator of nuclear factor-κB (RANK) ligand (RANKL), has recently been used to treat patients with giant cell tumor of bone (GCTB). However, few reports have described the clinical results of denosumab therapy for spinal GCTB and evaluated treatment efficacy with respect to the entirety of the resected vertebra after denosumab therapy. METHODS: We present the case of a 51-year-old man with T12 GCTB that was completely removed by a total spondylectomy following 10 courses of neoadjuvant denosumab therapy...
