Clear cell chondrosarcoma (CCCS) is a rare variant of conventional chondrosarcoma with low-grade malignant features that may be confused radiographically and histologically with chondroblastoma. We report a case of a 50-year-old female who presented with 6 months of left hip pain. Initial radiographs demonstrated an osteolytic lesion with adjacent area of sclerosis in the proximal left femur. Magnetic resonance imaging demonstrated a marrow-infiltrative lesion with periosteal reaction and thickened enhancing periosteum...

Mesenchymal chondrosarcoma (MCS) is an unusual tumor mainly found in the skeleton. Around third of the cases occur in extra-skeletal sites with the orbit being the third most common site in these cases. In previous reviews of the orbital cases, it has been concluded that orbital MCS tends to occur in women in the second or third decades of life. However, 8 cases of orbital MCS have been reported so far in the pediatric age group (age less than 18 years-old) one of which has been considered congenital MCS in a 5-days old newborn girl...

Background: Chondrosarcoma is a mesenchymal malignant tumor composed of tumor cells producing cartilage. It is more commonly found in older age group and usually affects the axial skeleton. Intracranial chondrosarcoma is extremely rare, and chondrosarcoma arising from the sellar region are even rarer with only a few cases described in the literature. We report a case of chondrosarcoma mimicking a sellar suprasellar mass with parasellar extension. Case Description: A 22-year old male presented with generalized intermittent headache along with diplopia and diminished visual acuity without any history of sexual dysfunction or galactorrhea...

Thoracic outlet syndrome (TOS) is caused by heterogeneous factors that compress the brachial plexus and subclavian artery; tumor is rarely a cause of TOS. Here, we present the case of a 26-year-old man with secondary chondrosarcoma arising from osteochondroma of the left clavicle causing TOS, with a direct compression of the brachial plexus and subclavian artery. Immediately after surgery, the symptoms of TOS reduced. To our knowledge, this is the first case of a secondary chondrosarcoma of the clavicle causing TOS, which is possibly the key symptom for diagnosing malignant transformation of osteochondroma of the clavicle...

Mesenchymal chondrosarcoma (MCS) is a malignant cancer of the cartilage that accounts for less than 1% of all chondrosarcomas and typically occurs within the bone. One-third of all mesenchymal chondrosarcomas are extraosseous soft tissue sarcomas, rendering this as an uncommon entity. We report a rare case of an extraosseous chondrosarcoma with the cervical spinal canal in a 21-year-old male. The purpose of this case report is to discuss the imaging characteristics of this pathology proven diagnosis.

Extraskeletal myxoid chondrosarcoma (ESMC) is an extremely rare variant of chondrosarcoma accounting for less than 10% cases. It affects mainly the soft tissues of the proximal end of long bones. Its incidence in the head and neck region is less than 5%. This case presented in the nasopharynx, an exceedingly unusual site for ESMC in a 60-year-old female with left-sided nasal obstruction and occasional epistaxis of one-year duration. Biopsy from the nasopharyngeal mass was suggestive of low-grade chondrosarcoma...

This case report describes the rare occurrence of two individually uncommon tumours found in synchronous manner in an otherwise healthy patient with no history of malignancy. We believe this to be the first reported case of synchronous glioblastoma and chondrosarcoma. While primary rib lesions metastasising to brain are rarely reported and primary brain lesions metastasising to rib are even rarer still, there were no previous reports in the literature of synchronous brain and rib dual primary pathology that we could identify...

Mesenchymal chondrosarcoma is rare and can be challenging to diagnose. Herein, we report a minute mesenchymal chondrosarcoma within an osteochondroma. A 12-year-old girl presented with an asymptomatic exophytic lesion of the rib. The tumor was clinically diagnosed as osteochondroma, and was excised after observation for 3years. The resected specimen revealed an unexpected minute (0.9cm) "monophasic" mesenchymal chondrosarcoma in the apex of the lesion. The sarcoma consisted of monomorphic spindle cells without hyaline cartilage...

BACKGROUND: Chondrosarcomas account for approximately 20% of bone sarcomas, with the most common site being the lower limb. Hemipelvectomies that involve hindquarter amputation have previously been the treatment of choice for pelvic tumors. However, with advances in chemotherapy, radiotherapy, imaging and surgical techniques more patients are now being treated with limb salvage surgery. The rehabilitation outcomes following an internal hemipelvectomy have not been well identified and there is currently little, if any, gait analysis data on rehabilitation following hemipelvectomy in limb salvage patients...

Surgical resection is the only treatment for chondrosarcomas, because of their resistance to chemotherapy and radiotherapy; therefore, additional strategies are crucial to treat chondrosarcomas. Peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-activated transcription factor, which has been reported as a possible therapeutic target in certain malignancies including chondrosarcomas. In this study, we demonstrated that a nonsteroidal anti-inflammatory drug, zaltoprofen, could induce PPARγ activation and elicit anti-tumor effects in chondrosarcoma cells...

Undifferentiated solid tumors with small blue round cell histology and expression of CD99 mostly resemble Ewing sarcoma. However, they also may include other tumors such as mesenchymal chondrosarcoma, synovial sarcoma, or small cell osteosarcoma. Definitive classification usually requires detection of entity-specific mutations. While this approach identifies the majority of Ewing sarcomas, a subset of lesions remains unclassified and, therefore, has been termed "Ewing-like sarcomas" or small blue round cell tumors not otherwise specified...

Extra-axial chordoma is an exceedingly rare tumor, with only 28 cases reported in the literature to date. Axial and extra-axial chordoma exhibits complete morphologic and immunophenotypic (expression of brachyury) overlap. However, in consideration of the non-canonical presentation, extra-axial chordoma is under-recognized and often misdiagnosed, most often as extraskeletal myxoid chondrosarcoma or myoepithelioma. To increase our understanding of the clinicopathologic features of extra-axial chordoma, six cases have been retrieved from the files of the Istituto Ortopedico Rizzoli and of the General Hospital of Treviso...

Background: Plasmacytomas are monoclonal proliferations of plasma cells that typically affect the intramedullary axial skeleton. Imaging findings of an extramedullary plasmacytoma on radiograph and computed tomography can be nonspecific and can resemble other entities such as lymphoma, metastases, chondrosarcomas, or giant cell tumors. Case Report: A 60-year-old female with a medical history of partial complex seizures, hypertension, diabetes, glaucoma, and hyperlipidemia presented with complaints of superficial abdominal pain associated with erythema and swelling for 3 weeks...

The diagnosis of mesenchymal chondrosarcoma, a distinctive biphasic malignant neoplasm harboring the HEY1-NCOA2 gene fusion and consisting of primitive round to spindled cells admixed with foci of relatively mature hyaline cartilage, is usually straightforward by morphological evaluation alone. However, in the setting of a limited biopsy, specimens lacking cartilage generate a broad differential diagnosis, encompassing a variety of other primitive sarcomas, including spindle cell/ sclerosing rhabdomyosarcoma...

Chondrosarcoma is a rare malignancy characterized by the production of cartilage matrix, displaying heterogeneous histopathology and clinical behavior. Due to lack of effective treatment for advanced disease, the clinical management of metastatic chondrosarcoma is exceptionally challenging. Chondrosarcomas harbor molecular abnormalities, such as overexpression of platelet-derived growth factor receptor (PDGFR)-alpha and PDGFR-beta, which are required for cancer development, progression, and metastasis. Pazopanib is a potent and selective multitargeted tyrosine kinase inhibitor, which co-inhibits stem cell growth factor receptor (c-KIT), fibroblast growth factor receptor (FGFR), PDGFR, and vascular endothelial growth factor receptor (VEGFR) and has demonstrated clinical activity in patients with advanced previously treated soft tissue sarcoma...

PURPOSE: The purpose of this study was to evaluate, during a national workshop, the inter-observer variability in target volume delineation for primary extremity soft tissue sarcoma radiation therapy. METHODS AND MATERIALS: Six expert sarcoma radiation oncologists (members of French Sarcoma Group) received two extremity soft tissue sarcoma radiation therapy cases 1: one preoperative and one postoperative. They were distributed with instructions for contouring gross tumour volume or reconstructed gross tumour volume, clinical target volume and to propose a planning target volume...

Long ischemia times adversely affect free flap survival, and large muscle flaps are particularly vulnerable. Hypothermic machine perfusion (HMP) is a well-established method of organ preservation, and recent literature has detailed the use of HMP to extend free flap ischemia times, predominantly in the laboratory setting. One limitation in the study and adoption of free flap HMP has been the availability of standardized perfusion machinery, as thus far institutions have built their own devices. We present a case of a 75-year-old woman with dedifferentiated chondrosarcoma of her right proximal femur...

IMPORTANCE: Transoral robotic surgery has revolutionized the practice of head and neck surgery over the past decade, with indications now expanding to include laryngeal pathology. Although laryngeal chondrosarcoma is a rare entity, trends in otolaryngology literature suggest that it can frequently be managed with conservative approaches. We hope to inspire other head and neck surgeons to consider transoral robotic surgery for the treatment of such tumors so that outcomes data can be collected and studied...
