Clinical History

A man of 57 with recurrent pain in the right thigh for one year showed no abnormality on clinical examination but on x-ray showed bony absorption associated with expansion and periosteal reaction at the upper end of the right femur. Biopsy was followed by radiotherapy and subsequent excision of the upper femur. A prosthesis was inserted and post-operative recovery was satisfactory.


The specimen comprises the head, neck and upper third of the shaft of the right femur, sawn longitudinally and mounted to display the cut surface. In the medullary cavity of the upper portion of the shaft is an ovoid tumour mass 6.5 cm in maximum diameter. The tumour is not encapsulated and has a haemorrhagic cut surface with pale hyaline and cystic areas. Histologically this is a low grade chondrosarcoma.
