1 OSTEOCHONDROMA Cartilage capped exostosis
Commonest benign tumour of bone Metaphyseal developmental abnormality D FRANTZEN OSTEOCHONDROMA

2 INCIDENCE 45 % of benign bony tumours 12 % of all bony tumours
Become evident < 20 yrs Solitary or multiple Any enchondral ossification bone D FRANTZEN OSTEOCHONDROMA

3 CLINICALLY Lump or mechanical problem Tendon or nerve irritation
Sessile or pedunculated 50% distal femur, proximal tibia, proximal humerus D FRANTZEN OSTEOCHONDROMA

4 CLINICAL Active growth during puberty
Move towards diaphysis during growth Excise if troublesome in second decade D FRANTZEN OSTEOCHONDROMA

5 RADIOLOGY Flat/ sessile / pedunculated Tumour blending into metaphysis
Pedunculated orientated proximally Cartilage cap with calcification D FRANTZEN OSTEOCHONDROMA

6 PATHOLOGY Normal bone covered by normal cartilage cap
Cartilage cap resembles normal growth plate Cartilage more disorganized D FRANTZEN OSTEOCHONDROMA

7 PATHOLOGY Covered by thin layer of periosteum
Binucleate chondrocytes in lacunae D FRANTZEN OSTEOCHONDROMA

8 TREATMENT Nil required unless symptomatic
Extra-capsular marginal excision Recurrence < 5% D FRANTZEN OSTEOCHONDROMA

9 PROGNOSIS Risk of malignancy if solitary - 0.2 %
Risk of malignancy in diaphyseal aclasia : - 20 % Sarcomatous changes usually low- grade D FRANTZEN OSTEOCHONDROMA
