CHONDROSARCOMA

CHONDROSARCOMA

Clinical History

A 53 year old man noticed a gradual swelling in his thigh over a period of 6 months. The tumour was apparently completely removed by excision. Most chondrosarcomas are intimately associated with bone and cartilage but, as in this case, they may originate in the soft tissues.

Pathology

Specimen shows an oblong mass lying in fat and connective tissue with some associated muscle. It's edge can be distinctly defined from the surroundings. The cut surface appears pearly but there are central spots of haemorrhage. The histological features of this tumour are those of a chondrosarcoma.
