Description
This shows the lower end of the femur, with an epiphyseal plate apparent. The lower-third of the
femoral shaft does not appear to contain tumour, although there is tumour near the mid-area; the
cortex is eroded and the periosteum expanded by tumour which, on one side, is haemorrhagic and
partly necrotic, while on the other there is white tumour tissue. A 'sun-ray' appearance in the white
tumour area can be imagined.
