FEMUR - Chondrosarcoma

The specimen is the distal femur. There is a pale semi-lucent tumour mass situated in the lateral condyle of the femur. This extends to the articular cartilage and infiltrates the metaphyseal medullary space. In areas the tumour shows widespread cystic degeneration with associated haemorrhage. The tumour occurred in a 61 year old female and on histologic examination was shown to be a grade II chondrosarcoma.
