Introduction:
Osteochondroma is a bony lesion arising from the surface of the bone. It com-prises a large percentage of all benign bone tumors. A unique feature of this tumor is the conti-nuity of cortical and medullary components between the normal bony tissue and aberrant tissue of osteochondroma. Even though the predominant composition is bone, growth takes place in the cartilaginous portion. The incidence of osteochondroma in flat bones which are ossified by intramembranous type of ossification including the scapula, clavicle, ribs, and pubic ramus is usually rare.
Case Report:
We report three cases of osteochondroma involving less common and unusual sites. We have included one case of osteochondroma of the medial end of the clavicle, one case of iliac wing osteochondroma, and one case of radial head osteochondroma.
Conclusion:
Osteochondroma rarely occurs in unusual sites. Although uncommon, osteochon-droma can involve small and flat bones.
