What is difference between chondroma and enchondroma?
Chondromas are very rare, benign tumors made of cartilage. They usually grow slowly and develop in the sinuses and the bones of the skull. They can also show up in the small bones of the hands, feet, upper arms, thighs and ribs. If they form in the marrow cavity of bones, they are called enchondromas.
What causes chondroma?
The exact cause of enchondroma is not known. However, it is thought to happen due to either of the following: Overgrowth of the cartilage that lines the ends of the bones. Persistent growth of original, embryonic cartilage.
What is a periosteal bud?

How is Chondroma treated?

What is dedifferentiated chondrosarcoma?
Dedifferentiated chondrosarcoma (DDCS) is a type of cartilaginous tumor that is comprised of two distinct components: (1) low-grade chondrogenic components and (2) high-grade noncartilaginous sarcoma. It constitutes 1-2% of all primary bone tumors [1. J. Bruns, W.
What is a chondral rest?
In those locations the most reliable indicator of malignancy is the presence of a soft tissue mass. Lesion size greater than 4.0 or 5.0 cm is more often seen in chondrosarcoma. 2,3. A chondroid lesion less than 1.0 cm in size is referred to as a cartilaginous rest, an indolent lesion.
What is the size of periosteal chondromas?

Can you feel periosteal chondromas?
Periosteal Chondromas. In many cases, periosteal chondromas will cause swelling and a dull, aching pain. Some people are able to feel the tumor mass, particularly those with chondromas on the fingers and toes. Tumors in the fingers and toes are also more likely to cause painful symptoms.
What is the difference between soft tissue chondromas and periosteal chondroma?
A periosteal chondroma develops on the surface of bone, out of the periosteum, which is a strong membrane that covers bones. Soft tissue chondromas are not connected to bone. They most often form on the tendons that attach muscles to bone or to the tendon sheaths that keep tendons in place next to bone.
What are the symptoms of chondromas?
In some cases, periosteal chondromas will cause swelling and a dull, aching pain. Some people are able to feel the tumor mass, particularly those with chondromas on the fingers and toes. Tumors in the fingers and toes are also more likely to cause pain.
