Extraskeletal chondroma is a type of chondroma that arises in soft tissue rather than within the bones. Chondromas are tumors made up of cartilage tissue. They can occur in various parts of the body, including the bones, joints, and soft tissue. Extraskeletal chondromas are typically small, slow-growing tumors that are benign, meaning they are not cancerous.
Most people with extraskeletal chondroma do not experience any symptoms. The tumor is often discovered incidentally on an X-ray or other imaging test done for a different reason. However, in some cases, the tumor can cause pain or discomfort, particularly if it is located near a nerve or a joint. In rare cases, the tumor may grow large enough to cause compression of nearby structures.
Extraskeletal chondromas are a rare type of benign cartilaginous tumor that can develop outside the bone. They are typically slow-growing and usually found in the soft tissues of the body, such as the skin, subcutaneous tissues, and muscles. Extraskeletal chondromas can occur at any age, but they are most commonly found in adults.
Types
Here is a list of the different types of extraskeletal chondroma and their characteristics:
- Soft Tissue Chondroma: This type of extraskeletal chondroma is the most common and is found in the soft tissues of the body. It is typically small in size and does not cause any symptoms. Soft tissue chondromas are usually discovered incidentally on imaging studies, such as X-rays or MRIs.
- Subcutaneous Chondroma: Subcutaneous chondromas are found just beneath the skin and are often mistaken for lipomas. They are usually small in size and do not cause any symptoms. However, they may cause pain or discomfort if they press against nearby nerves or blood vessels.
- Juxtacortical Chondroma: Juxtacortical chondromas are found adjacent to the bone surface and are often associated with the cartilage of the joint. They are typically small in size and do not cause any symptoms. However, if they grow too large, they can compress adjacent structures and cause pain or discomfort.
- Intraosseous Chondroma: Intraosseous chondromas are found within the bone and are typically slow-growing. They are most commonly found in the long bones of the arms and legs and may cause pain or discomfort as they grow. Intraosseous chondromas can sometimes cause bone fractures if they weaken the bone.
- Extraskeletal Mesenchymal Chondrosarcoma: This is a rare and aggressive type of extraskeletal chondroma that can transform into a malignant tumor called chondrosarcoma. It typically occurs in young adults and can occur in any part of the body. Extraskeletal mesenchymal chondrosarcoma can cause pain, swelling, and difficulty moving the affected limb.
Causes
While the exact cause of extraskeletal chondroma is unknown, several factors have been identified that may contribute to the development of this condition and discuss the top causes of extraskeletal chondroma in detail.
- Genetic Factors: Genetic mutations or inherited disorders such as multiple hereditary exostoses (MHE) have been associated with extraskeletal chondroma development. MHE is a condition that causes multiple bone tumors to form throughout the body.

- Use of Hormonal Medications: Use of certain hormonal medications, such as those used in hormone replacement therapy (HRT), may increase the risk of developing extraskeletal chondroma.
- Chronic Exposure to Sunlight: Chronic exposure to sunlight has been linked to an increased risk of developing extraskeletal chondroma.
Symptoms
They can develop anywhere in the body, except in bones. These tumors often grow slowly and do not cause symptoms until they become large. Here are the most common symptoms of extraskeletal chondroma:
- Lump or bump: A firm, painless lump or bump may develop under the skin, usually in the soft tissues, such as the fingers, toes, or ears.
- Skin discoloration: The skin over the tumor may turn red or bluish.
- Swelling: The area around the lump may become swollen.
- Tenderness: The lump may be tender or painful to the touch.
- Restricted movement: If the lump is near a joint, it may limit movement in that area.
- Numbness: The tumor may compress nerves, causing numbness or tingling sensations.
- Weakness: If the tumor presses on a nerve, it can cause muscle weakness.
- Stiffness: The area around the tumor may become stiff, making movement difficult.
- Fatigue: In some cases, the tumor may cause fatigue or weakness due to its size.
- Headaches: If the tumor is located in the skull, it may cause headaches.
- Vision problems: A tumor near the eye may cause vision problems, such as double vision or blurred vision.
- Hearing problems: If the tumor is near the ear, it may cause hearing loss or ringing in the ears.
- Breathing difficulties: A tumor in the chest may cause breathing difficulties or coughing.
- Abdominal pain: A tumor in the abdomen may cause abdominal pain or discomfort.
