Cartilage Tumours

The cartilage tumours can be benign or malignant. Differentiating benign and malignant chondroid tumours by histology alone is difficult. Clinical and radiological correlation is very essential. Other cartilage lesions which mimic tumours are fracture callus, costochondral junction and intervertebral disc. This chapter describes how to diagnose different chondroid lesions/tumours such as enchondroma, osteochondroma,chondroblastoma, chondromyxoid fibroma, chondrosarcoma, subungual exostosis and BPOP.
