Clear cell chondrosarcoma is a rare variant of chondrosarcoma that mostly involves the end of long bones. However, nine cases have been reported in the head and neck: four in larynx, two in nasal septum, two in maxilla and one in the skull. These cases form the basis of this review. Head and neck cases accounts for less than 5% of Clear cell chondrosarcomas in the whole body and the larynx is t...

Chondrosarcoma is one of the most common types of primary bone cancer that develops in cartilage cells. Resveratrol (Res), a natural polyphenol compound isolated from various fruits, has a suppressive effect on various human malignancies. It has been shown that Res inhibits matrix metalloproteinase (MMP)-induced differentiation in chondrosarcoma cells. However, the effects of Res on cell prolif...

Chondrosarcoma of the hyoid bone is rare. Only 14 cases have been reported in the literature, to date. We present a case of chondrosarcoma of the hyoid bone with imaging, surgical, and pathologic correlation, and a review of the literature.

In this report, we describe an unusual case of chondrosarcoma that involved the entire bimaxillary and nasal skeleton. The pathogenesis, correlation of histopathology with radiology, and management of chondrosarcoma are reviewed.

RATIONALE Chondrosarcoma, characterized by the production of cartilage matrix, is a common bone tumor, accounting for 20% to 27% of all malignant bone tumors. It often occurs in the cartilage of the pelvis, femur, tibia, and humerus. However, chondrosarcoma of the patella is extremely rare. PATIENT CONCERNS The present study describes a case of chondrosarcoma affecting the right patella in a ...

BACKGROUND Mesenchymal chondrosarcoma is a rare malignant tumor arising from bone or soft tissues. Instraspinal dumbbell-shaped mesenchymal chondrosarcoma is even rarer; however, it should not be neglected by clinicians. CASE PRESENTATION A 26-year-old female was referred to our hospital with a 1.5-month history of sciatic pain and numbness in the left leg. Computed tomography and magnetic re...

Chondrosarcoma is a malignant tumor of cartilage; it may be primary, originating inside a bone (central) or from the periosteum (peripheral), or secondary, initiating through malignant change in osteochondromas [6,7]. Microscopically, the malignant c ells produce characteristic chondroid and fibrous matrix. Macroscopically, the chondrosarcoma develops on the bone surface, as large masses rangin...

Background: Chondrosarcomas are rare non-epithelial malignant tumours. Surgery is the primary treatment option for chondrosarcoma, with adjuvant therapy having a minor role. In cases of nasal chondrosarcoma, however, en bloc total removal by open approaches is often undesirable. Here we report a case of chondrosarcoma arising from the nasal septum, which was resected endoscopically. Case Report...

Mesenchymal chondrosarcoma is a rare tumor that is distinctly different from classic chondrosarcoma. The prognosis of this tumor is poor, with a high incidence of locoregional and distant metastases. It shows a predilection for the head and neck, however mesenchymal chondrosarcoma of hyoid bone has rarely been reported. We experienced a case of mesenchymal chondrosarcoma of the hyoid bone in a ...

Chondrosarcoma is one of the most common malignant bone tumors in adults. It use to affect upper arm, pelvis and thigh bone. A wide surgical extirpation represent the gold standard to treat this disorder. In fact, radiotherapy and chemotherapy are no useful. Interestingly, chondrosarcoma is rare in head and neck (HNCS) and extremely uncommon during pregnancy. Thus, there is a lack of evidence a...
