Multicentric chondrosarcomas, other than those from mesenchymal chondroma, are rare and difficult to differentiate from metastatic disease. Eight new patients with multicentric chondrosarcomas are reported. Five patients had chondrosarcomas that were monomelic, 3 had disseminated chondrosarcomas, 3 had synchronous involvement, and 5 had metachronous ...

The purpose of this article is to identify the typical imaging features of periosteal chondrosarcoma on radiography, CT, and MRI.Periosteal chondrosarcoma is a rare low-grade malignant cartilaginous tumor arising from the external surface of bone. Imaging features are often specific.

Dedifferentiated chondrosarcoma
Skeletal Radiology, 1995We reviewed 74 cases of dedifferentiated central and peripheral chondrosarcoma. Histologically these tumours consist of an underlying cartilaginous component (either benign or malignant) juxtaposed to a high-grade non-cartilaginous component, with a typically abrupt transition between the two tissue types. The non-cartilaginous component may constitute

Chondrosarcoma is a malignant tumor that arises from cartilage. In the maxillary area, the tumors spread locally but may also invade blood vessels and metastasize systemically. Initial surgical resection is the treatment of choice.

Secondary chondrosarcoma is a distinctive type of tumor that originates from a preexisting cartilaginous lesion. Most commonly, it is associated with solitary or multiple osteochondromas. A fraction of cases arises from other conditions, such as Maffucci syndrome and Ollier disease.

Tracheal chondrosarcomas are rare, with only 14 cases previously documented. We report a case of chondrosarcoma of the trachea and review other published cases. Our patient was a 34-year-old man who began to feel shortness of breath 8 months after initial hemoptysis.

Chondrosarcomas are malignant bone tumors with pure hyaline cartilage differentiation; myxoid changes, calcification, or ossification may be present. Several subtypes of chondrosarcomas exist. Behavior patterns vary, ranging from slow-growing nonmetastasizing lesions to aggressive metastasizing sarcomas. Symptoms are usually mild, with duration ranging

Thoracic extraskeletal chondrosarcomas are uncommon tumors. A case of primary chondrosarcoma of the pleura is presented. Complete surgical resection without adjuvant therapy, even in the presence of pleural seeding, appears to offer a favorable long-term prognosis.

Dedifferentiated chondrosarcoma: An aggressive variant of chondrosarcoma
Asian Cardiovascular and Thoracic Annals, 2014Dedifferentiated chondrosarcomas are a rare and aggressive subtype of chondrosarcoma with a bimorphic pattern on histopathology. Rib is a rare site of dedifferentiated chondrosarcoma. Diagnosis of this subtype preoperatively can be challenging. Treatment options for dedifferentiated chondrosarcoma are limited because they are chemoresistant, and ...

This article presents a review of chondrosarcoma variants, with a focus on the extraordinarily rare variants of chondrosarcoma in which hyaline cartilage is not the dominant feature. Discussed are the differential diagnoses for these neoplasms, radiologic studies, gross and microscopic features, and prognosis. Summaries are provided of the key features
