[Mesenchymal chondrosarcoma of the radius with metastases in the internal organs]

A rare variant of chondrosarcoma--a mesenchymal chondrosarcoma of the right radiocarpal articulation--is described. The tumour was very small, painless, and did not disturb the joint function but possessed a high mitotic activity and gave lymphogenic metastases to the viscera of the right half of the body. It was not diagnosed clinically.
