The most common benign bone tumour is:

• A Giant cell tumour
• B Osteochondroma (osteocartilaginous exostosis) ✓
• C Non-ossifying fibroma
• D Enchondroma

Explanation

Osteochondroma is the most common benign bone tumour and accounts for approximately 35–40% of all benign bone tumours. It arises from a cartilaginous cap on a bony stalk, typically from the metaphysis of long bones, growing away from the physis. Multiple hereditary exostoses (MHE) is an autosomal dominant condition with EXT1/EXT2 mutations carrying a 1–5% risk of malignant transformation to chondrosarcoma. Solitary osteochondromas have a <1% malignant transformation risk and are observed unless symptomatic.
