Giant cell tumor of bone

İsa Kaya, Murat Benzer, Göksel Turhal, Gode Sercan, Cem Bilgen, Tayfun Kirazlı
Giant cell tumor (GCT) is a benign tumor that originates from undifferentiated mesenchymal cells of the bone marrow. The cranium as well as temporal bone is a rare location for GCTs. Despite its benign nature, GCT may be locally aggressive and has the potential to recur locally. Furthermore, GCT may give rise to pulmonary metastases (~1%) in addition to causing local bone destruction. Surgical excision is the treatment of choice for patients with GCT. We describe the case of a 56-year-old female who presented with headache and hearing loss with extensive GCT, which originated in the squamous part of the temporal bone and extended into the left mandibular fossa and middle ear...

BACKGROUND: Diagnosing giant cell-rich bone tumors can be challenging on limited biopsies. H3 histone family member 3A (H3F3A) (G34W/V/R/L) mutations are present in the majority of giant cell tumors (GCTs) of bone and H3 histone family member 3B (H3F3B) (K36M) mutations are present in nearly all chondroblastomas, but are absent in histologic mimics. Mutation-specific immunohistochemistry (IHC) is highly specific for GCT and chondroblastoma in surgical excisions. The objective of the current study was to validate H3G34W and H3K36M IHC in the diagnosis of giant cell-rich bone tumors on fine-needle aspiration and core needle biopsy specimens...

Dentinogenic ghost cell tumor (DGCT), a rare, benign odontogenic tumor with aggressive behavior, causes bone destruction and cortical expansion. We report here a case of DGCT in a 38-year-old male, presenting with enormous extraoral protrusion, which radiographically was predominantly radiolucent with radiopaque areas. Microscopically, it was observed to be a solid ameloblastomatous proliferation with pseudoglandular structures associated with clusters of ghost cells. Abundant dentinoid material adjacent to the epithelial sheets containing entrapped epithelial tumor cells was also evident...

PURPOSE: Denosumab, a new monoclonal antibody that inhibits receptor activator for nuclear factor Kβ ligand (RANKL), has recently been approved by FDA for the treatment of aggressive giant cell tumor of bone (GCTB). So we initiated this study to evaluate the clinical benifits of denosumab used preoperatively or postoperatively. METHODS: Patients diagnosed with classic sacral GCT without metastasis were included in this study. Patients were assigned into 3 groups according to the use of denosumab: control group 1, post-operative group 2 and neoadjuvant group 3...

A 28-year-old woman presented with a mass in her right leg, which, on plain radiograph, appeared as a lytic lesion in the mid-shaft of the tibia with cortical thinning but without periosteal reaction. Tc-MDP 3-phase bone scan demonstrated intense uptake in the periphery of the mass with a photopenic center, the so-called doughnut sign. Histopathology revealed a capillary hemangioma. This case demonstrates that the doughnut sign on bone scan can be caused by capillary hemangioma in addition to other reported bone pathologies, including aneurysmal bone cyst, giant cell tumor, and telangiectatic osteosarcoma...

Background: Data on long-term prognosis of metastatic GCT (mGCT) is scant. The frequency of spontaneous regressions (SRs) is unknown. We aimed to estimate the prognosis of mGCT. Methods: We searched electronic scientific literature databases and generic Internet from January 1980 to August 2017. After identifying eligible studies we performed descriptive analyses and meta-analyses to estimate overall survival (OS), disease specific survival (DSS) and frequency of SRs in the years before the widespread use of denosumab...

It is commonly accepted that wide en bloc resection followed by reconstruction is essential in progressive lesions (Campanacci grade III) for local control of possible recurrence. However, specific grade III can be downgraded and treated with intralesional curettage to preserve better wrist function, without increasing the recurrency rates. In this report, Grade III giant cell tumor of the distal radius was successfully treated using vascularized osseous graft from the inner lip of the iliac bone in addition to downgrading strategy...

BACKGROUND: Osteoscopy is a minimally-invasive endoscopic technique for inspecting lesions inside bone marrow cavities. We describe the feasibility of osteoscopic surgery of giant cell tumor of bone (GCTB) in order to preserve the proximal fibula, and thereby achieve immediate recovery and avoid complications. PATIENTS AND METHODS: Five patients with GCTB in the proximal fibula were treated using osteoscopic curettage with adjuvants (argon plasma coagulation and cementation)...

Giant cell tumor of bone (GCTB) is a benign but locally aggressive tumor, which can cause significant bone destruction at the epiphysis of long bones. Recent studies have demonstrated that norcantharidin (NCTD) can inhibit the proliferation and migration of various human cancer cells, but the role of NCTD in GCTB has not previously been evaluated. The aim of this study was to explore the nature of the anti-cancer effects of NCTD in GCTB and to elucidate the biomolecular mechanisms responsible for these effects...

Histone H3 encoding genes, particularly H3F3A and H3F3B, the genes encoding the variant histone H3.3, are mutated at high frequency in pediatric brain and bone malignancies. Compared to the extensive stidues on K27M and K36M mutations, little is known about the mechanism of G34 mutations found in pediatric glioblastoma (GBM) or giant cell tumors of the bone (GCTB). Here we report that unlike the K27M or K36M that affect global histone methylation, the GCBT G34 mutations (G34L/W) only affect histone H3K36 and H3K27 methylation on the same mutated histone tails (in cis), a mechanism distinct from known histone mutations...

Myeloid sarcoma is an extramedullary tumor that consists of myeloblasts or immature myeloid cells. The neoplasm can occur in any part of the body, including the bone, periosteum, lymph nodes, skin, and soft tissue and they may occur de novo or in association with acute myeloid leukemia, myeloproliferative neoplasms and myelodysplastic syndromes. Most cases display a myelomonocytic or pure monoblastic morphology. Tumors with megakaryoblastic differentiation are extremely uncommon and may occur in association with transformation of a myeloproliferative disorder...

Background: In our previous study, mouse double minute 2 homolog (MDM2), insulin-like growth factor 1 (IGF1), signal transducer and activator of transcription 1 (STAT1), and Rac family small GTPase 1 (RAC1) were correlated with the recurrence of giant cell tumor of bone (GCT). The aim of this study is to use a large cohort study to confirm the involvement of these four genes in GCT recurrence. Methods: The expression of these four genes was detected and compared between GCT patients with or without recurrence...

BACKGROUND: Giant cell tumor of bone (GCTB) is an osteolytic, locally aggressive, rarely metastazing bone tumor. This is a retrospective study evaluating a large series of GCTB patients treated with denosumab in routine practice in 6 European reference centers. METHODS: Patients with locally advanced, unresectable or metastatic GCTB, treated with denosumab outside clinical trials were eligible. Primary end-point was progression-free survival (PFS) for all patients; secondary end-points were: type of surgery, relapse rate and event-free survival for patients after preoperative denosumab + surgery...

We herein report two cases of Fanconi syndrome with refractory hypophosphatemic osteomalacia that was difficult to correct by phosphorus replacement therapy. The pathological result was a bony giant cell tumor and osteosarcoma, respectively. Interestingly, after resection of the tumors, the patient with osteosarcoma recovered completely but the patient with the bony giant cell tumor had a relapse. Although she underwent nine operations, her symptoms and laboratory tests did not improve. These findings indicate that Fanconi syndrome can result from a bone tumor...

Brown tumor of the jaws is a manifestation of hyperparathyroidism consisting of osteolytic lesions that show proliferation of multinucleated giant cells in the maxilla and/or mandible. Differential diagnosis of these lesions from local central giant-cell granuloma is mandatory for the correct treatment of the patient. Radiographic and histopathological exams of the jaw lesion are not sufficient to determine the diagnosis, which requires laboratory tests including serum levels of calcium, alkaline phosphatase, parathyroid hormone (PTH) and phosphate, and radiographic examination of other bones as well, such as hand-wrist, pelvis, and femur...

Giant cell tumors(GCT) of bone is benign bone tumors with aggressive and osteolytic activity. As traditional treatment of GCT, removal of bone graft is disease with high local recurrence rate, and could reduce local recurrence by auxiliary means. Different surgical methods such as prosthesis replacement, wide resection and En-bloc resection could be selected for different parts of giant cell tumor of bone, based on the lesion location, size, extent of invasion, recurrence rate. For patients with special region of GCT of bone with removed incompletely and high surgical risk expected, arterial embolism could be performed...
