How would you describe enchondroma?

An enchondroma is a type of benign bone tumor that originates from cartilage. It is not cancerous. It most often affects the cartilage that lines the inside of the bones. Enchondromas are the most common type of hand tumor.

How can you tell the difference between chondrosarcoma and enchondroma?

Enchondroma consists of regular lobules and mature connective tissue with low cellularity; well-differentiated chondrosarcoma is composed of irregular lobules with highly cellular fibrous tissue.

Do enchondromas grow radiology?

Three out of 55 (5.45%) of long bone enchondromas exhibited growth at a median of 23 (range 21 to 25) months follow-up. The first growing lesion was discovered incidentally in a 48 year-old healthy male and was located in his distal femur.

Should an enchondroma be removed?

In the majority of cases, enchondromas do not require treatment. In rare cases, however, multiple tumors may weaken the bone, causing it to fracture. When this occurs, surgery may be needed to remove the tumor and prevent additional fractures.

Can an enchondroma grow?

In general, after skeletal maturity, enchondromas do not grow and rarely cause pain. Endosteal scalloping may occur with enchondromas.

What is the treatment for enchondroma?

Typically, no treatment is necessary for an enchondroma. Most abnormalities detected within the bone can be rechecked with normal x-rays over a period of time.

Is enchondroma a chondroma?

enchondroma: within the bone (within the medullary cavity), periosteal chondroma: on the surface of the bone, soft tissue chondroma in the soft tissue. Enchondroma is usually a solitary benign lesion in intramedullary bone.

Is enchondroma a Chondroma?

When should an Enchondroma be removed?

Can an Enchondroma grow?

Should an Enchondroma be removed?

How is the appearance of an enchondroma determined?

Enchondromas have a somewhat variable appearance by imaging, although characterization by excluding suspicious features is key. Since most are asymptomatic incidental findings, lesions in a characteristic location and appearance are not usually further investigated.

Can a bone cyst be an enchondroma?

Other differentials for this appearance would include a giant cell tumor or an aneurysmal bone cyst (with ABC thought much less liklely). On delayed planar imaging, intense osteoblastic activity is seen within the proximal phalanx of the left 3rd finger, consistent with an enchondroma.

Where is the expansile lytic lesion in an enchondroma?

Right: A well-defined, slightly expansile, lytic lesion is seen in the proximal phalanx (white circle) through which the fracture has occurred. Enchondroma. There is an expansile, lytic lesion of the 5th metacarpal (red arrow) containing amorphous matrix calcifications (white arrow) characteristic of an enchondroma.

How to tell if you have enchondroma or endosteal scalloping?

Often no findings, but may be local tenderness at site of an active lesion Expansile lesions in the hand may cause a palpable bony mass History, physical examination, and plain x-rays must be considered together and are the most valuable modalities for identification of an enchondroma. Endosteal scalloping/ erosion in a long bone lesion
