Primary extraskeletal myxoid chondrosarcoma of the pulmonary arteries is a very rare entity. Multimodality imaging reports on this entity are few. Myxoid chondrosarcoma is characterized by chondroid and neurogenic differentiation in extraskeletal locations. These tumours represent fewer than 2.5% of all soft-tissue sarcomas, and are most commonly found in the lower extremities, limb girdles, di...

A 45-year-old female presented with complaint of a lump in the right breast for the last 6 months. Excisional biopsy had been performed outside our institution, which was suggestive of a pure mammary chondrosarcoma. Modified radical mastectomy of the right breast was performed and histopathology was suggestive of a pure mammary chondrosarcoma of the right breast. One axillary lymph node was pos...

Radiation-induced sarcoma is a rare complication of radiation therapy. We report a case of radiation-induced chondrosarcoma of the maxilla. An 80-year-old Persian woman developed radiation-induced chondrosarcoma of the left maxilla 7 years after combined chemotherapy and external beam radiation therapy for the Ann Arbor stage IE malignant lymphoma of the right tonsil. She underwent suboptimal t...

Chondrosarcoma, a primary malignancy of bone, has eluded successful treatment with modern chemotherapeutic and radiation regimens. To date, surgical resection of these tumors remains the only curative treatment offered to patients with this diagnosis. Understanding and exploring the nature of chemotherapy and radiation resistance in chondrosarcoma could lead to new molecular targets and more di...

Chondrosarcoma is an uncommon malignant neoplasm of cartilaginous origin. Extraskeletal chondrosarcomas are far less common than their intraosseous counterparts, representing approximately 2% of all soft tissue sarcomas. Clinically, extraskeletal mesenchymal chondrosarcoma (EMC) shows a very fast progression. It also has a high incidence of local recurrence and distant metastasis. The most comm...

Purpose. Clear cell chondrosarcoma is a rare variant of chondrosarcoma. Six cases are herein reported.Subjects. We have treated six patients with clear cell chondrosarcoma in the past 28 years, representing 1.6% of all chondrosarcomas seen in this time period.Results and Discussion. Half the patients had been initially underdiagnosed and inappropriately treated.Conclusions. Our results and our ...

High grade chondrosarcoma is characterized by its lack of response to conventional cytotoxic chemotherapy, the tendency to develop lung metastases, and low survival rates. Research within the field prioritizes the development and expansion of new treatment options for dealing with unresectable or metastatic diseases. Numerous clinical trials using the proteasome inhibitor bortezomib have shown ...

UNLABELLED Pathologic fractures of the proximal femur resulting from primary bone sarcomas are often difficult to treat and some are often not recognized resulting in inappropriate interventions prior to the correct diagnosis being made. The aim of the study was to identify factors determining the survival after pathologic fractures of the proximal femur resulting from nonosteogenic primary bon...

BACKGROUND AND AIMS Well-differentiated chondrosarcoma and enchondroma are similar in histopathologic aspects; therefore, special methods should be used to make a distinction between these benign and malignant tumors. The aim of this study was to evaluate the efficacy of a histopathologic method in the long-term follow-up for differentiating these lesions. MATERIALS AND METHODS The medical re...
