“…Other authors have reported high malignancy rates of 51 to 66 % [10, 11], suggesting that physicians should consider the presence of malignancy when a bone tumor is suspected in the clavicle. In a recent large-scale report by Ren et al [6], the benign/malignant ratio was 1.34 among 206 clavicle-origin bone tumors. In the current case, characteristic roentgen imaging findings were suggestive of a GCT; however, the possibility of malignancy could not be completely excluded because of the imaging findings, including PET, and the rare site of origin.…”

“…However, the national bone tumor registry in Japan reported two cases of GCTs in the clavicula (1.1 %) from 2006 to 2012 [5]. Although bone tumors rarely occur in the clavicle, a high proportion of those that develop at this site are malignant [6, 7]. Therefore, establishing a list of preoperative differential diagnoses of bone tumors involving the clavicles is often difficult.…”

BackgroundMost bone tumors that occur in the clavicle are malignant. A few giant cell tumors (GCTs) of the clavicle have been reported; however, the most appropriate operative method for this tumor has never been discussed.Case presentationA 54-year-old man noticed enlargement of the proximal aspect of the right clavicle. A plain X-ray revealed lytic change and ballooning of the proximal end of the right clavicle. The tumor was isointense on T1-weighted magnetic resonance images and showed a mixture of low- and high-intensity areas on T2-weighted images without extension to the surrounding soft tissues. Bone scintigraphy showed strong accumulation (normal/tumor ratio, 2.31), and positron emission tomography revealed strong uptake of fluorine-18-2-fluoro-2-deoxy-d-glucose (SUVmax, 6.0) in the proximal part of the right clavicle. Because we could not completely exclude malignancy, an open biopsy was performed. Pathologically, the tumor comprised mononuclear stromal cells and multinuclear giant cells, resulting in a diagnosis of a GCT of the bone. Although curettage may be considered for such lesions (Campanacci grade II), we chose resection to minimize the chance of recurrence. The tumor was resected en-bloc with the proximal half of the clavicle. No postoperative shoulder disproportion was observed, and full range of motion of the right shoulder was maintained. The patient was satisfied with the surgical outcome (Musculoskeletal Tumor Society score of 96 %). He returned to his original job as a land and house investigator without any signs of recurrence for 1 year after surgery.ConclusionsAlthough GCT of the bone rarely occurs in the clavicle, the typical X-ray findings demonstrated in the present case are helpful for a correct diagnosis. Although en-bloc resection without reconstruction is appropriate for GCTs in expendable bones, there has been much discussion about shoulder function after total claviculectomy. Considering the importance of the function of the clavicle, which is to support the scapula through the acromioclavicular joint, we preserved the muscle attachments of the deltoid, trapezius, and pectoralis major. Because both the oncological and functional outcomes were satisfactory, we recommend preservation of as much of the clavicle as possible in patients with clavicular bone tumors.

“…A review of the published data revealed that there are two detailed case reports and two case series of clavicular chondrosarcoma, but only the case reported by Nakazora et al1 refers to a primary myxoid extraskeletal chondrosarcoma arising from the clavicle 1,2,6,7. Deik et al8 also reported a case of extraskeletal myxoid chondrosarcoma arising supraclavicularly, causing an interesting clinical presentation.…”

“…Tl-201 (thallium), Tc-99m-sestamibi, Tc-99m-tetrofosmin and metabolic positron (PET) radiopharmaceuticals are characterized as tumor seeking agents, and many times have been found to be useful in the initial diagnosis, grading, and post-therapy evaluation of primary bone tumors. Nevertheless, the importance of bone scintigraphy for the evaluation of bone tumors has decreased over the last several years, with the exception of osteosarcomas, where this method is still valuable; however, the accuracy of a bone scan can be increased by using SPECT and SPECT/CT 7,8…”

Juxtacortical chondrosarcoma is a rare primary malignant cartilaginous tumor accounting for 0.2% of all bone tumors. Wide surgical resection is the treatment of choice for juxtacortical chondrosarcomas. Accurate preoperative diagnosis is important in ensuring appropriate management, staging, and treatment of the patient. A combination of radiographs, three-dimensional imaging with computerized tomography (CT) scan and magnetic resonance imaging (MRI) can typically allow accurate diagnosis of juxtacortical chondrosarcomas. Bone scan and chest x-ray or CT chest scans are indicated for appropriate staging of the patient. Pet scan, ultrasound, bone scan, etc. are not typically needed for the diagnosis. Certainly, pulmonary imaging and bone scan are required for staging and could be commented upon.
