Received Jan. 2012; Received in revised form May 2012; Accepted July 2012. ABSTRACT Chondrosarcomas are slow-growing, malignant mesenchymal neoplasms characterized by formation of cartilage by the tumoral cells. They display a wide range of morphological features from a well-differentiated growing mass resembling a benign cartilage tumour to a high-grade malignancy with aggressive local invasio...
Canine extraskeletal osteosarcomas are extremely rare tumors. Over a period of 25 years at the Animal Medical Center, approximately 1,000 cases of skeletal osteosarcomas have been diagnosed. During the same period 11 cases of extraskeletal osteosarcomas and three extraskeletal chondrosarcomas were diagnosed. Tumors of the mammary gland were excluded. Extraskeletal osteosarcomas were found in th...
Today, ultrasound imaging is being widely used to assess soft tissue lesions in the maxillofacial region. However, ultrasound investigations of intra-osseous lesions are rare, especially for tumors of the jaws. This report emphasized the capability of this useful imaging modality in identification of the characteristics of malignant conditions involving the bone. Mesenchymal chondrosarcoama, on...
Mesenchymal chondrosarcomas (MCs) account for 3-10% of primary chondrosarcomas. The cytogenetic literature includes only ten such tumours with karyotypic information and no specific aberrations have been identified. Using a purely molecular genetic approach a HEY1-NCOA2 fusion gene was recently detected in 10 of 15 investigated MCs. The fusion probably arises through intrachromosomal rearrangem...
