What is a Juxtacortical chondroma?
Juxtacortical chondromas, also known as periosteal chondromas, are rare benign chondral tumors that arise from the periosteum of tubular bones. They are thought to account for ~2% of benign bone tumors.
How common are chondromas?
Chondromas account for 25 percent of all benign bone tumors. The exact cause is unknown. Enchondromas are the most common type of bone tumor found in the hand.
Is Juxtacortical chondroma benign or malignant?
Juxtacortical tumors are composed of a variety of histologic tissue types. The most common types are those producing cartilage or bone. Chondroma is a benign tumor composed of mature hyaline cartilage. Typically, it is centrally located, but it may be seen in a juxtacortical position, arising from the periosteum.
What does chondroma mean?
(kon-DROH-muh) A rare, slow-growing tumor that is made up of cartilage and forms on or in bones or soft tissue. It is not cancer. The tumor usually occurs in the hands or feet, but it may also occur in the upper arm, thigh, collarbone, ribs, pelvis, spine, skull, and nasal sinuses.
What does Juxtacortical mean?
Juxtacortical is a general term and merely denotes ‘next to cortex’ and can be used in a variety of context depending on the structure (e.g. bone, brain, kidney etc.).
Where is the Juxtacortical located?
Juxtacortical small lesion (JCSL) is a special type of white matter lesion, defined as no greater than 5 mm in diameter and adjacent to the cerebral cortex in location.
Is Osteoblastoma malignant?
Although osteoblastoma is considered a benign tumor, there have been very rare cases in which an osteoblastoma has transformed into a malignant (cancerous) tumor.
How is Chondroma treated?
Surgical removal is the primary treatment for chondromas.
What causes Chondroma?
The exact cause of enchondromas is unknown. Some research indicates that they may result when cells turn into cartilage instead of bone. It is not believed that the tumors are caused by radiation or chemical exposure or by any specific activity.
What is cortical and Juxtacortical?
Can multiple sclerosis lesions go away?
“Paradoxically, we see that lesion volume goes up in the initial phases of the disease and then plateaus in the later stages,” Zivadinov says. “When the lesions decrease over time, it’s not because the patient lesions are healing but because many of these lesions are disappearing, turning into cerebrospinal fluid.”
