Osteochondroma is an overgrowth of cartilage and bone that happens at the end of the bone near the growth plate. Most often, it affects the long bones in the leg, the pelvis, or the shoulder blade.
Growth plates are areas of developing cartilage tissue near the ends of long bones in children. Bone growth occurs from the growth plate, and when a child is fully grown, the growth plates harden into solid bone.
В osteochondroma tumors generally arise in patients aged between 10 and 18. You can mostly find osteochondroma in children and young adults. Symptoms generally depend on the size and location of the osteochondroma tumor.
Debate continues as to whether osteochondroma is a developmental disorder (pseudotumoral lesion) or a neoplasm. 1 nonetheless, irrespective of whether it is a pseudotumoral lesion or a more common benign bone tumor,2 it is certainly an exostosis (external bone proliferation that deforms the bone).
Because an osteochondroma often displays no symptoms, the tumor may only be discovered when a child notices a bump, or reports pain. For some children, the osteochondroma may never be discovered. An osteochondroma looks like a bony projection on the external surface of a bone, like a bony mushroom on a stalk, usually near a growth plate area.
Chest radiograph (tangential view) was done which showed bony growth over the 6th rib on the lateral aspect (fig 2). Osteochondroma of the rib was suspected as it did not increased in size since last few years as per the history given by the patient. We now have a 3 yrs follow up of the patient without any complication to the patient.
