Overview
Osteochondroma (also known as osteocartilaginous exostoses) is a benign bone tumor that consists of cartilage and bone. Osteochondromas arise from cartilage, which is normally involved in the mechanical support of the bone. These tumors take the form of cartilage-capped bony projections or outgrowth on the surface of bones, also known as exostoses.[1] Osteochondroma is the most common benign bone tumor and usually occurs in the metaphyseal region of the long bones. Development of osteochondromas is the result of the developmental anomaly of skeletal growth.The majority of these tumors present as solitary, non hereditary lesions. Osteochondromas are usually found in adolescents and children. Men and women are equally affected. The incidence of osteochondroma is approximately 0.9 per 100,000 individuals. If left untreated,progression occurs slow and is then followed by malignant transformation. The treatment choice for osteochondroma is surgical removal of solitary lesion or partial excision of the outgrowth, when symptoms cause motion limitations or nerve and blood vessel impingements.

Differentiating Osteoid Osteoma from other Diseases
Osteochondroma must be differentiated from other diseases that cause a growth after skeletal maturity, a palpable lump, and a malunited fracture such as enchondroma, chondroblastoma, and intraosseous ganglion.
Epidemiology and Demographics
Osteochondroma is the most common benign bone tumor among general population. The incidence of osteochondroma is approximately 0.9 per 100,000 individuals in the general population. The incidence of osteochondroma decreases with age; the median age at diagnosis is between 10 to 13 years. Males and females are equally affected with osteochondroma. Osteochondroma usually affects individuals of the Caucasian race.
