Chondrosarcomas are uncommon tumors which originates in the head and neck and accounts for approximately 10 to 15% of all cases. Most chondrosarcomas exhibit an indolent growth pattern. Nasoseptal tumors may mimic common sinonasal conditions, making early diagnosis difficult. We report a case of nasoseptal metastatic chondrosarcoma which was atypical, characterized by an aggressive growth pattern and widely disseminated.

J Can Dent Assoc, 2007 Mar;73(2):175-8.

PMID: 17355810

Chondrosarcomas are malignant tumours of cartilaginous origin. They range from a well-differentiated growth resembling a benign cartilage tumour to a high-grade malignancy with aggressive local behaviour and the potential to metastasize. Only 5% to 10% of chondrosarcomas are known to occur in the head and neck region. A case of chondrosarcoma of the anterior region of the mandible is presented, along with a review of the relevant literature.

Mesenchymal chondrosarcoma - A rare cause of pleural effusion

Cheo SW, Abraham AD, Madatang A, Low QJ

Med J Malaysia, 2020 07;75(4):458-460.

PMID: 32724019

Mesenchymal chondrosarcoma is a malignant neoplasm arising from cartilaginous bone or soft tissue. It is uncommon yet devastating. Our patient was a 21-year-old man who presented with pleuritic chest pain and weight loss. His chest radiograph showed left pleural effusion. His pleural effusion analysis was consistent with exudative pleural effusion. Tuberculosis workup was negative. Pleural fluid cytology did not yield malignant cells. Subsequently, his computed tomography of thorax showed left rib sclerotic lesion with soft tissue component. Biopsy of the soft tissue eventually confirmed the diagnosis of mesenchymal chondrosarcoma. He succumbed to his illness before the diagnosis was confirmed. We hope that through this case report, we are able to provide some insight into this rare condition.

Mesenchymal chondrosarcoma is a rare disease with poor prognosis. Treatment including wide or radical excision is very important. Radiotherapy and chemotherapy are additional treatment options, but no conclusive results for their efficacy have been shown until date. Imaging modalities can give important clues for diagnosis and management planning. Angioembolization before surgery could be useful as prophylaxis to control intraoperative bleeding, increasing the likelihood of complete resection.

Chondrosarcoma (CS) is a malignant tumour of long and flat bone characterised by the formation of cartilage. Mesenchymal chondrosarcoma (MCS) is a rare subtype of CS that is more aggressive and may lead to erroneous diagnosis in a limited biopsy. The diagnosis is mainly based on the histopathological appearance of biphasic pattern of undifferentiated small round cells separated by islands of well-differentiated hyaline cartilage. We report a case of 13-year-old boy who initially presented with gum swelling and the biopsy result suggested a benign fibrous lesion. Following an extensive lesion shown in radiologic findings, the tumour excision was done and finally was diagnosed as an MCS of the maxilla. The patient was given postoperative chemotherapy (EURO-EWING 99 regimen), and now on regular follow-up for monitoring of local recurrence or tumour metastasis.

Contrasting increased levels of serum amyloid A in patients with three different bone sarcomas: An indicator of tumor malignancy?

Wan-Ibrahim WI, Ashrafzadeh A, Singh VA, Hashim OH, Abdul-Rahman PS

Electrophoresis, 2016 09;37(17-18):2328-37.

PMID: 27062367 DOI: 10.1002/elps.201500522

Sarcoma is a malignant tumor that originates from the bone or soft tissue. In this study, abundances of serum amyloid A (SAA) in patients with pleomorphic sarcoma (PS), chondrosarcoma (CS), and osteosarcoma (OS) were analyzed and compared with those from their respective age-matched healthy control subjects. Results obtained from our analysis by 2DE showed that the levels of SAA were markedly elevated in patients with PS and OS, which are highly metastatic, while in patients with CS, which is a less aggressive sarcoma, the increase appeared less pronounced. A similar trend of altered abundances was also observed when the levels of SAA in the subjects were estimated using Western blot, ELISA, and multiple-reaction monitoring analyses. Absolute quantification using multiple-reaction monitoring further demonstrated that the increased abundance of SAA in patients with PS, OS, and CS was mainly attributed to isoform SAA1. In view of the different degrees of tumor malignancy in PS, OS, and CS, our data suggest their apparent correlation with the levels of SAA in the patients.

PMID: 26581086 DOI: 10.2119/molmed.2015.00183

Diagnosis of bone tumor currently relies on imaging and biopsy, and hence, the need to find less invasive ways for its accurate detection. More recently, numerous promising deoxyribonucleic acid (DNA) and protein biomarkers with significant prognostic, diagnostic and/or predictive abilities for various types of bone tumors have been identified from genomics and proteomics studies. This article reviewed the putative biomarkers for the more common types of bone tumors (that is, osteosarcoma, Ewing sarcoma, chondrosarcoma [malignant] and giant cell tumor [benign]) that were unveiled from the studies. The benefits and drawbacks of these biomarkers, as well as the technology platforms involved in the research, were also discussed. Challenges faced in the biomarker discovery studies and the problems in their translation from the bench to the clinical settings were also addressed.

Primary sacral tumours are rare, therefore experience of managing their associated complications are very limited. Effective surgical treatment of pelvic chondrosarcoma remains a major challenge for orthopaedic surgeons, due to the complex anatomic structure of the pelvis, the lack of defined compartment borders, the close vicinity to vital structures, and the risk of jeopardizing pelvic structural stability. We report a rare case of a giant sacral chondrosarcoma (100cm x 80cm) in an elderly male who successfully underwent tumour resection with good functional outcome and recovery. Long term follow up is essential in view of the possibility of local tumour recurrence.

Chondrosarcoma of the spine is rare; it presents predominantly in very young males and presentation with neurological deficit is uncommon. Treatment of this type of tumour is mainly through surgery as adjuvant therapy is ineffective. En bloc resection of tumours in the spine are difficult although it remains the recommended treatment for chondrosarcoma. We report here presentation of a female with paresis (Frankel C) whom was diagnosed with a large chondrosarcoma of the T2 vertebra extending to the right upper thoracic cavity. The patient underwent radical xcision through an anterior and posterior approach to the spine.

PMID: 18705458 MyJurnal

Osteosarcoma is a rare tumour in the sinonasal region. Early diagnosis is essential for adequate management and better prognosis and this requires a meticulous histopathological examination. Reported is a case of osteosarcoma misdiagnosed as chondrosarcoma and treated by surgery followed by radiotherapy. However, appropriate diagnosis and pre-operative chemotherapy would have been significant in the prognosis. The pitfall of accurate diagnosis and the subsequent treatment is discussed in order to find the ways to maximize five years survival which is not more than 25% in this type of lesions.

PMID: 12440279

Removal of the whole sternum for malignant tumours results in a large defect, causing severe deformity and possible paradoxical movements of the chest wall. The reconstruction of the resultant large defect of the chest wall is often complex and difficult. Commonly used materials include rib autograft, steel strus acrylic plate and various synthetic meshes such as Goretex or Marlex mesh, with a myocutaneous flap for coverage. A case of a 48-year-old man with sternal chondrosarcoma successfully treated with thoracoplasty using acrylic plate-marlex mesh combination following near total resection of sternum is reported.

Extraskeletal myxoid chondrosarcoma (EMC) is aggressive in children. The condition in children differs to that in adults and to skeletal myxoid chondrosarcoma. We report on a 9-year-old girl with EMC in her left thigh. She underwent above-knee amputation. Five months later, a small mass was noted at the right lower lobe of the lung. The patient underwent one course of ifosfamide, carboplatin, and etoposide chemotherapy, followed by resection of the mass and 8 more courses of chemotherapy. At the 2-year follow-up, she was in remission radiologically.

Immunolocalization of notch signaling protein molecules in a maxillary chondrosarcoma and its recurrent tumor

Siar CH, Ha KO, Aung LO, Nakano K, Tsujigiwa H, Nagatsuka H, et al.

Eur J Med Res, 2010 Oct 25;15(10):456-60.

PMID: 21156405

BACKGROUND: notch receptors are critical determinants of cell fate in a variety of organisms. Notch signaling is involved in the chondrogenic specification of neural crest cells. Aberrant Notch activity has been implicated in numerous human diseases including cancers; however its role in chondrogenic tumors has not been clarified.

METHOD: tissue samples from a case of primary chondrosarcoma of the maxilla and its recurrent tumor were examined immunohistochemically for Notch1-4 and their ligands (Jagged1, Jagged2 and Delta1) expression.

RESULTS: both primary and recurrent tumors were histopathologically diagnosed as conventional hyaline chondrosarcoma (WHO Grade I). Hypercellular tumor areas strongly expressed Notch3 and Jagged1 in spindle and pleomorphic cells suggesting up-regulation of these protein molecules at sites of tumor proliferation. Expression patterns were distinct with some overlap. Differentiated malignant and atypical chondrocytes demonstrated variable expression levels of Jagged1, and weak to absent staining for Notch1, 4 and Delta1. Protein immunolocalization was largely membranous and cytoplasmic, sometimes outlining the lacunae of malignant chondrocytes. Hyaline cartilage demonstrated a diffuse or granular precipitation of Jagged1 suggesting presence of soluble Jagged1 activity at sites of abnormal chondrogenesis. No immunoreactivity for the other Notch members was observed. Calcified cartilage was consistently Notch-negative indicating down-regulation of Notch with cartilage maturation. Stromal components namely endothelial cells and fibroblasts variably expressed Notch1, 3 and Jagged1 but were mildly or non-reactive for the other members.

CONCLUSIONS: Results indicate that Notch signaling pathway may participate in cellular differentiation and proliferation in chondrosarcoma. Findings implicate Notch3 and Jagged1 as key molecules that influence the differentiation and maturation of cells of chondrogenic lineage.
