Findings

The cut section of a long bone, presumably the femur, reveals a tumor resembling cartilage (glistening and blue-grey in color) that has eroded through the cortex.

Impression

Chondrosarcoma

Clinical Pathologic Correlation
This tumor is second only to osteosarcoma in frequency and occurs twice as often in males as in females. It tends to occur in older people (peak incidence in the 6th decade), and arises in central portions of the skeleton, e.g. shoulder, pelvis, proximal femur and ribs.

Pathology Pointer

Chondrosarcoma is a tumor composed of malignant mesenchymal cells that produce a cartilaginous matrix.
