CHONDROSARCOMA OF HUMERUS
This specimen was removed from a 50 year old man who was first diagnosed as having a well differentiated chondrosarcoma almost 20 years previously. The slowly growing tumour was initially controlled by local resection and bone grafting but ultimately recurred. X-ray showed a tumour with an irregular trabeculated pattern and with small areas of punctuate calcification. These radiological appearances suggested chondrosarcoma. Histology confirmed the macroscopic and radiological diagnosis of well differentiated chondrosarcoma.
