Genes and miRNAs involved in sarcomagenesis related pathways are unknown and therefore signaling events leading to mesenchymal cell transformation to sarcoma are poorly elucidated. Exiqon and Illumina microarray study on human chondrosarcoma JJ012 and chondrocytes C28 cell lines to compare and analyze the differentially expressed miRNAs and their gene targets was recently published in the Journ...

Chondrosarcoma (CS) is an uncommon malignant mesenchymal tumour showing cartilaginous differentiation which rarely presents in the jaws. CS represents 10-20% of all malignant bone tumours and less than 5% of tumours in head and neck region. Among the infrequent subtypes of CS, dedifferentiated CS is a sinister variant that presents with singular features and has extremely poor prognosis. We rep...

A 3 year old intact male pygmy goat developed progressive weakness and eventual recumbancy over the course of 1 week, while maintaining its ability to eat and drink. The animal died and at necropsy, the parietal pleural surfaces and the pericardial surface were noted to be covered with firm, white, variably sized nodules that often formed linear arrays or coalesced into larger clumped aggregate...

Chondrosarcoma is a rare malignant cartilage forming tumour usually arising from long bones and rarely seen in cranium. In cranium it is seen to commonly arises from skull base with skull vault being a highly unusual site. We report a case of a 30-year female presenting with complaints of headache for 6 months found to have a large chondrosarcoma in right fronto-parietal region which is an extr...

Chondrosarcoma is a common malignant bone tumor, which accounts for 20% of all malignant bone tumors. It often occurs in the long bones, but the incidence of scapular chondrosarcoma is rare. Here, we describe a case of a large chondrosarcoma occurring in the scapula which was treated with Malawer limb salvage surgery. The patient retained considerable limb function after complete removal of the...

Osteochondroma is the most common form of benign bone tumors. Chondrosarcoma a rare malignant tumor that may be primary or secondary. We report case 19-year-old man with low grade chondrosarcoma secondary to transformation osteochondroma right distal femur. Here we discuss osteochondroma, chances malignancy chondrosarcoma, work up done in our case, histopathological features differentiate from ...
