JSTOR Daily: SOLITARY OSTEOCHONDROMA OF THE DISTAL THIRD METACARPAL BONE IN A TWO-YEAR-OLD WHITE RHINOCEROS (CERATOTHERIUM SIMUM) SOLITARY OSTEOCHONDROMA OF THE DISTAL THIRD METACARPAL BONE IN A TWO-YEAR-OLD WHITE RHINOCEROS (CERATOTHERIUM SIMUM) Two men buried long ago in a medieval graveyard in Co. Donegal had a genetic condition called multiple osteochondromas, which causes benign bone tumors. One of the disease mutations is a new discovery ...
Osteochondroma is a noncancerous growth of cartilage and bone. (“Osteo” means bone, “chondro” means cartilage and “oma” means tumor.) It's the most common kind of benign bone tumor. It usually appears near the ends of long bones, where new bone growth occurs in children and teens. Osteochondroma is the most common benign tumor of bone.
osteochondroma, [1][2] The tumors take the form of cartilage -capped bony projections or outgrowth on the surface of bones (exostoses). [3][4] It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone. 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. Osteochondromas are benign chondrogenic lesions derived from aberrant cartilage from the perichondral ring that may take the form of solitary osteochondroma, or Multiple Hereditary Exostosis.
osteochondroma, Patients typically present between the ages of 10 and 30 with a painless mass. What is osteochondroma? An osteochondroma, also known as an osteocartilaginous exostosis, is one of the most common benign bone tumors. This type of tumor is continuous with the underlying bone − meaning that both the tumor and healthy bone share the same hollow cavity that contains the bone marrow. Osteochondromas represent the most common bone tumor, accounting for 20% to 50% of all benign osseous tumors. [1] [2] Osteochondromas are surface bone lesions composed of both cortical and medullary bone with hyaline cartilage caps.
Osteochondroma is the most common type of benign (non-cancer) bone tumor. It is sometimes called an exostosis. An osteochondroma is a bony spur or outgrowth that generally appears near the growth plate (a layer of cartilage at the ends of long bones) on the thighbone, shinbone, upper arm or hip. A normal osteochondroma will not grow after your child stops growing.
