Patient ReportsWhat is Chondroma? Diagnosis and Treatment
Written by Medicover Team and Medically Reviewed by Dr Neelesh Kanderi , Oncologists
Table of Contents
Chondroma is a benign tumor made up of mature cartilage cells that commonly develops inside or on the surface of bones. It most often affects the small bones of the hands and feet but can also occur in long bones and other parts of the skeleton. Many chondromas do not cause symptoms and are discovered incidentally during imaging tests performed for other reasons.
Larger tumors may cause pain, swelling, restricted joint movement, or increase the risk of fractures. Diagnosis is confirmed through imaging studies and, in some cases, a biopsy to exclude malignant bone tumors. Treatment depends on the size, location, and symptoms, with surgical removal recommended for symptomatic or suspicious lesions.
What are the Types of Chondromas?
Chondromas are classified based on their location within or around the bone and soft tissues.
- Enchondroma: Develops within the medullary cavity of a bone and is the most common type, frequently affecting the small bones of the hands and feet.
- Periosteal Chondroma: Forms on the surface of the bone beneath the periosteum and is less common than enchondromas.
- Soft Tissue Chondroma: A rare type that develops in soft tissues rather than within the bone, usually affecting the hands and feet.
What are the Causes of Chondroma?
The exact cause of chondroma remains unclear. However, genetic factors and certain inherited conditions are believed to contribute to its development.
- Genetic mutations affecting cartilage growth
- Ollier disease
- Maffucci syndrome
- Abnormal cartilage cell development
- Rare inherited genetic disorders
What are the Symptoms of Chondroma?
Many chondromas do not cause symptoms and are discovered incidentally. Symptomatic tumors usually occur when they enlarge or weaken the affected bone.
- Localized Pain: Pain near the affected bone, especially if the tumor presses on nearby structures.
- Swelling: Visible or palpable swelling over the affected area.
- Pathological Fractures: Bones weakened by the tumor may fracture after minor trauma.
- Limited Range of Motion: Reduced joint movement when the tumor is located close to a joint.
When to see a Doctor for Chondromas?
If you develop symptoms suggestive of a chondroma, consult an Oncologist promptly. Early evaluation can help confirm the diagnosis, monitor tumor growth, and rule out malignant bone tumors that may require specialized treatment.
- If you have persistent bone pain or swelling that does not improve with rest.
- If you notice a lump or swelling near a bone or joint.
- If you experience limited joint movement or stiffness.
- If you develop a fracture after a minor injury, especially in a bone with a known cartilage tumor.
- If imaging tests reveal a cartilage tumor or abnormal bone growth that requires further evaluation.
- If you notice rapid enlargement of a previously diagnosed chondroma or worsening pain.
- If you have multiple chondromas or a family history of bone tumors.
- If your symptoms persist or worsen, consult an Oncologist promptly for comprehensive evaluation, diagnosis, biopsy if required, and appropriate treatment.

How is Chondroma Diagnosed?
Diagnosis involves clinical assessment, imaging studies, and, when necessary, histological confirmation through biopsy.
Clinical Evaluation
A detailed medical history and physical examination help identify symptoms, swelling, tenderness, and functional limitations.
Imaging Studies
- X-rays: Detect the location, size, and appearance of the cartilage tumor.
- Magnetic Resonance Imaging (MRI): Evaluates the extent of the tumor and its relationship to surrounding soft tissues.
- Computed Tomography (CT) Scan: Provides detailed cross-sectional images of the bone and tumor.
Histological Examination
A biopsy may be performed to confirm the diagnosis and differentiate a benign chondroma from malignant cartilage tumors.
What are the Treatment Options for Chondroma?
Treatment depends on the tumor's size, location, symptoms, and the risk of complications.
Observation
Small, asymptomatic chondromas may only require periodic monitoring with follow-up imaging.
Surgical Treatment
- Curettage: Surgical scraping of the tumor from the affected bone.
- Bone Grafting: Bone graft material may be used to fill the cavity after tumor removal.
- En Bloc Resection: Complete removal of the affected bone segment may be necessary for larger or recurrent tumors.
Post-Surgical Care
Rehabilitation and follow-up imaging help restore function and detect recurrence at an early stage.

What are the Complications and Prognosis of Chondroma?
Most chondromas have an excellent prognosis after appropriate treatment. However, a few complications may occur.
- Recurrence: Rarely occurs if the tumor is not completely removed.
- Malignant Transformation: Although uncommon, some chondromas may rarely develop into chondrosarcoma.
Frequently Asked Questions
1. What are the symptoms of chondroma?
Symptoms may include painless lumps or masses, typically found in the bones or cartilage, with potential for growth.
2. What causes chondroma?
Causes are typically linked to genetic mutations affecting cartilage cell growth, with sporadic occurrences most common.
3. How is chondroma diagnosed?
Diagnosis typically involves clinical evaluation, imaging studies like X-rays or MRIs, and biopsy for histopathological examination.
4. What treatment options are available for chondroma?
Treatment may include surgical excision of the tumor and monitoring for recurrence.
5. How does chondroma relate to cartilage tumors?
It is classified as a benign cartilage tumor, with potential for growth but generally low risk of malignant transformation.
