What is Giant Cell Tumor of Tendon Sheath?
Written by Medicover Team and Medically Reviewed by Dr Ramakoteswara Rao K , Orthopedics
Giant Cell Tumor of Tendon Sheath (GCTTS) is a slow-growing, usually noncancerous lump that develops in the lining of the tendon sheaths, most commonly in the hands or fingers. It forms when cells multiply abnormally in the soft tissues around joints or tendons, often causing swelling, discomfort, or restricted movement in the affected area.
What are the Symptoms of Giant Cell Tumor of the Tendon Sheath?
Giant Cell Tumor of Tendon Sheath often shows up as a small lump near a joint, most commonly in the fingers or hands. It usually grows slowly and might not hurt at first.
Common symptoms include
- A firm, painless lump near a tendon or joint
- Swelling that may come and go.
- Stiffness or reduced movement in the nearby joint
- Mild discomfort or aching, especially with movement
- A feeling of tightness or pressure in the area
What Are the Common Causes of Giant Cell Tumor of Tendon Sheath?
Giant Cell Tumor of Tendon Sheath usually forms due to changes in the tendon lining, but the exact cause isn't always known. However, certain triggers may play a role in its development.
Common causes include
- Repetitive joint or tendon use: Ongoing strain can irritate the tendon sheath, leading to abnormal tissue growth.
- Trauma or injury: A past injury near the joint may contribute to tumor formation.
- Inflammation: Long-term inflammation in the joint or surrounding tissue might lead to changes in the tendon sheath.
- Genetic predisposition: Some cellular changes linked to genetics may influence its development.

Get Second OpinionHow Is Giant Cell Tumor of Tendon Sheath Diagnosed?
Diagnosing Giant Cell Tumor of Tendon Sheath starts with a simple check of the lump. Since the tumor often forms near a joint or tendon, doctors focus on its size, location, and how it feels to the touch.
Common diagnostic steps include
- Physical exam: The doctor feels the lump and checks for movement, tenderness, and firmness.
- X-ray: Shows if nearby bones are affected or if the lump is pressing against them.
- Ultrasound: Helps tell the difference between a solid mass and a fluid-filled cyst.
- MRI scan: Gives detailed images of soft tissues to see how deep the tumor goes.
- Biopsy (if needed): A small tissue sample may be taken to confirm it's a benign tumor.
What Are the Treatment Options for Giant Cell Tumor of Tendon Sheath?
Treatment for Giant Cell Tumor of Tendon Sheath usually focuses on removing the lump and helping the joint move freely again. It's a slow-growing tumor, but it can come back if not treated properly.
Main treatment options include
- Surgical removal: The most common treatment is surgery to take out the entire tumor. This helps reduce the chance of it coming back. It's often a simple procedure, and most people heal well.
- Radiation therapy: If the tumor comes back or can't be fully removed, low-dose radiation may help stop it from growing again. This is more common in rare or widespread cases.
- Physical therapy: After surgery, gentle exercises may be needed to restore strength and improve joint movement, especially if stiffness was an issue.
- Medications (if needed): Pain relievers or anti-inflammatory medicines may be used to ease swelling or discomfort after surgery. In a few cases, targeted drugs may be suggested if the tumor returns.
When to See a Doctor?
If you notice a lump near a joint that doesn't go away or starts getting in the way of daily movement, it's a good idea to see a doctor. While the tumor is usually harmless, it can grow and cause joint problems if left untreated.
See a doctor if you notice
- A firm lump that stays for more than 2 to 3 weeks
- Swelling that slowly increases in size
- Pain or tenderness near the lump
- Trouble moving the joint or feeling stiffness
- Recurrence of the lump after previous removal
