UNASSIGNED: Giant cell tumor (GCT) is a benign locally aggressive tumor with features of frequent recurrence and metastatic potential. GCT of small bones of hand and feet is rare with high recurrence and potential to metastasis. This study aims to provide a case report of GCT of the first metatarsal treated with wide excision, autologous fibular grafting, and fixation with locking plate.
UNASSIGNED: An 18-year-old male patient presented with progressive swelling over the dorsomedial aspect of foot for 1 year. Upon clinical examination, the swelling was firm with local signs suggestive of a benign bony tumor arising from the base of first metatarsal of the left foot. Radiology reveals an expansile osteolytic lesion arising from the base of 1st metatarsal with coarse septations and features suggestive of a benign bone lesion. A core biopsy was obtained under local anesthesia and histopathology report suggested a GCT. Surgical intervention by en bloc excision and reconstruction by fibular autograft and stabilized with a locking plate was done. The patient was given a below-knee cast for 6 weeks postoperatively. Full weight bearing was started after 6 weeks. At 12 months of follow-up, the graft was well taken up and there were no signs of recurrence both clinically and radiologically.
UNASSIGNED: GCT of 1st metatarsal is a rare entity with higher recurrence rate compared to conventional GCT. En bloc excision and autologous fibular graft with plate fixation are preferred treatment options.

UNASSIGNED: Giant cell tumors of bone (GCTB) are infrequent tumors that usually impact the epiphyses of long bones and uncommonly manifest in the ribs. Herein, we report a case of asymptomatic GCTB directly invading the lung tissue.
METHODS: A 36-year-old man was referred to our emergency department with only left chest pain. Computed tomography revealed a large heterogeneous solid cystic mass in the left lung apex and amorphous calcification and distraction in the posterior part of the left fourth rib. Histological examination also exhibited that the GCTB originated from the rib. The patient underwent an en-bloc resection with no recurrence in his one-year follow-up.
UNASSIGNED: GCTB is characterized by osteoclast-like multinucleated giant cells and can exhibit aggressive local behavior. GCTB in the rib is rare, mainly found in the posterior arc. Radiographic features include lytic lesions with bone remodeling, often seen eccentrically in long bone epiphyses. Aggressive tumors may show cortical destruction and soft tissue extension. Surgery is often recommended for GCTB management, aiming for complete resection with sufficient surgical margins.
CONCLUSIONS: The absence of well-defined diagnostic criteria hinders the accurate diagnosis of GCTB, making a comprehensive assessment through radiological and histological examinations crucial. Upon physical examination, GCTB should be considered in the differential diagnosis for mediastinal lesions, regardless of their size. Furthermore, surgical removal can be taken into account as the primary treatment strategy for tumors that originate from the posterior arc of the ribs, such as GCTB.

UNASSIGNED: The management of distal radius giant cell tumors (GCTs) remains challenging, and the optimal approach is still a matter of debate. This systematic review and meta-analysis aimed to compare the outcomes of extended curettage and wide resection, the mainstays of treatment.
UNASSIGNED: Medline (via PubMed), Cochrane Library, Web of Science, Google Scholar, ClinicalTrials.gov, and Embase databases were searched for comparative studies that assessed extended curettage with adjuvant therapy and wide resection with reconstruction in patients with GCTs of the distal radius up to April 2023. Data were collected and analyzed on rates of local recurrence, metastasis, overall complications, and functional outcomes. The Newcastle-Ottawa scale was used to appraise the risk of bias within each study.
UNASSIGNED: Fifteen studies (n = 373 patients) were included and analyzed. Patients who underwent curettage were more likely to develop recurrence (risk ratio [RR] = 3.02 [95% confidence interval; CI, 1.87-4.89], P < .01), showed fewer complications (RR = 0.32 [95% CI, 0.21-0.49], P < .01), and showed greater improvement in Visual Analog Scale and lower Disabilities of the Arm, Shoulder, and Hand scores (P < .00001) than those who underwent wide resection. No significant difference was found regarding metastasis (RR = 1.03 [95% CI, 0.38-2.78], P = .95).
UNASSIGNED: Regarding the surgical approach to GCT of the distal radius, curettage with adjuvant therapy was associated with a higher likelihood of recurrence compared with wide resection with reconstruction. Nevertheless, the curettage approach resulted in significantly lower rates of operative complications, decreased pain scores, and better functional outcomes in comparison to the resection group.

UNASSIGNED: Giant Cell Tumours (GCT) are benign tumours with aggressive potential that disrupt the local bony architecture, which can be especially problematic in peri-articular locations. Our aim was to assess the outcomes of patients with GCT of the distal ulna who were treated by resection without reconstruction.
UNASSIGNED: The study included 21 patients with distal ulna GCT that were treated with resection without reconstruction. There were 12 males and 9 females, with a mean age of 30.4years (range 14-45 years). The patients mean follow-up period was 4.4 years, with a two-year minimum follow-up.
UNASSIGNED: Painful swelling was the presenting symtom in all cases. Nineteen patients had Campanacci grade 3 and two had Campanacci grade 2. The mean resected length of the distal ulna was 6.8 cm (range 4-10) cm. The Musculoskeletal Tumor Society score (MSTS) was 26.1. (range 22-28). Grip strength of the affected hand was reduced by 10.5% on average. (range 0%-16%). Two patients were having multi-centric disease on presentation and none of the cases had pathological fracture on presentation. One case had a local recurrence which was treated with surgery.
UNASSIGNED: Based on current study, GCT of the distal ulna, en bloc resection without reconstruction can be recommended as a valuable treatment option for Campanacci grades 2 and 3 tumours. Resection of the distal end of the ulna without reconstruction results in excellent functional outcomes, with forearm rotational movement and hand function preserved. According to review of literature this is the largest series of GCT Ulna and we recommend a multicentre and comparitive studies on this topic.

Giant cell tumors (GCTs) are rare, locally aggressive neoplasms that commonly affect the long bones. However, GCTs can also occur in the craniofacial region, including the maxilla. This case report presents a rare case of recurrent giant cell tumor of the maxilla in a 32-year-old male patient. The patient underwent a total maxillectomy with clear margins, which resulted in successful local control. This report highlights the clinical presentation, diagnostic approach, treatment modalities, and favorable prognosis associated with recurrent giant cell tumors of the maxilla.

UNASSIGNED: Giant cell tumors (GCTs) of bone in the carpus are rare. Carpal GCTs are usually solitary lesions; multifocal involvement is exceptional. These lesions have a higher risk of local recurrence after intralesional curettage than those in other body areas.
METHODS: We present a case of a 28-year-old male with a six-month history of a palpable mass in the dorsal aspect of the left wrist. Physical examination revealed a 2 cm, mildly tender mass. Magnetic resonance revealed a large intermediate signal lesion involving completely hamate bone and the distal portion of the triquetrum. Histological examination confirmed a giant cell tumor of the carpus. The patient underwent en-bloc resection of the hamate bone extending to the distal part of the pyramidal. The defect was reconstructed using polymethylmethacrylate cement (PMMA), and intercarpal arthrodesis with the capitate was achieved. Follow-up at 18 months revealed a good clinical evolution, wrist range of motion of 30° of extension, 30° of flexion, and 10° of ulnar and radial deviation without evidence of tumoral recurrence.
UNASSIGNED: The current literature suggests a high incidence of local recurrence in carpal GCT, so wide excision with carpal arthrodesis is recommended, especially in Campanacci III and multifocal involvement.
CONCLUSIONS: Carpal GCT is exceptional, mainly affecting the hamate, capitate, and scaphoid. Most literature supports wide excision of carpal GCT owing to the high recurrence rate with intralesional procedures.

Giant cell tumors of bone (GCT) are rare soft tissue tumors, that account for 3%-5% of primary bone tumors with <2% occurring in the head and neck. The nasal cavity is a highly unusual site of presentation. We reviewed 15 cases of GCT of nasal cavity and paranasal sinuses. We add 1 case to the literature. The case herein reported, appears to be the second nasal fossa GCT described in the literature and the first documented case with multifocal localization. A case of multifocal GCT of the nasal cavity is described. Although rare in the general population, GCT should be included among the possibilities in the differential diagnosis when evaluating tumors of the head and neck. Management of this particular tumor remains challenging; surgical removal is still the gold standard treatment, preferring a minimally invasive trans-nasal approach to reduce intra and post-operative morbidity.

UNASSIGNED: Brown tumor is a giant cell focal lesion of bone associated with hyperparathyroidism, even primary or secondary. Differential diagnosis of these lesions from others giant cell lesions of the jaw bone is mandatory for the correct treatment of the patient.
METHODS: We present here two cases of brown tumor affecting the jaws by describing their clinical aspects and radiographic features, diagnostic criteria and treatment of this disease.
UNASSIGNED: Brown tumor is one of the lesions that develop in patients with hyperparathyroidism or renal failure. Skeletal bones including maxillo-facial ones can be the site of this lesion, also radiographic and histopathological exams of the jaw lesion are not sufficient to determine the diagnosis, which requires laboratory tests and radiographic examination.
CONCLUSIONS: Dental surgeon should be aware of oral manifestations associated with systemic diseases, hence the importance of careful physical examination and thorough investigation for the diagnosis and treatment success. This article aims to illustrate the management strategy to aid clinicians in suspected cases of brown tumor.

Sacral masses can be removed using anterior, posterior, or combined approaches. Achieving total sacrectomy through a posterior-only approach results in a shorter procedure time, minimal tissue damage, and a reduced risk of complications. In this study, we aimed to share our experience with performing total sacrectomy using a posterior-only approach in 26 patients and to assess their clinical outcomes at our center.
This retrospective study examines the clinical progression, surgical response, and outcomes of 26 patients with various sacral mass pathologies. We accessed patient information from our hospital records.
The study included 14 men (54%) and 12 women (46%), with an average age of 49.8 years. Most cases had a normal body mass index, while 6 were overweight. Sacrectomy was performed at a high level in 12 patients and at a middle level in 14 patients. In addition to pain, motor deficits were observed in 9 patients, and sphincter dysfunction was found in 5. Preoperative embolization was conducted for 11 patients. The most prevalent lesions were chordoma (8 patients), malignant peripheral nerve sheath tumor (4 patients), giant cell tumor (3 patients), and solitary plasmacytoma (3 patients). Only 1 patient experienced a temporary partial motor deficit after surgery. There were no instances of cerebrospinal fluid leakage. Five patients experienced local recurrence, and 1 had distant metastasis.
Performing sacrectomy for large or giant sacral tumors through a posterior approach is both feasible and safe, resulting in reduced morbidity and no significant change in overall survival.

The distal radius is rarely affected by either primary or metastatic bone cancers. The most frequent tumors of the distal radius are giant cell tumors, which are benign tumors with the propensity to invade. En bloc excision of giant cell tumors of the distal radius achieves a low recurrence rate but compromises the wrist joint, necessitates a significant reconstruction, and has functional consequences. Reconstruction after en bloc resection of a distal radius bone tumor is challenging. Furthermore, orthopedic oncologists disagree on treating such long bone anomalies most effectively. The present article summarizes the various biological and non-biological reconstruction techniques performed after en bloc resection of a distal radius tumor, discusses the advantages and disadvantages of each reconstruction strategy, and summarizes several case studies and case reports.
