How do you get rid of a giant cell tumor of the tendon sheath?
Because the mass is frequently associated with the tendon sheath or synovial joint, complete excision can be difficult. Often, partial excision of the joint capsule or tendon sheath is necessary for complete removal of the tumor. Meticulous dissection and exploration are essential because satellite lesions are common.
Are giant cell tumors of the tendon sheath cancerous?
A tendon sheath is a layer membrane that covers a tendon. Tendons are fibrous tissue that connects muscle to bone. These tumors cause the affected synovium, bursae or tendon sheaths to thicken and overgrow. They are benign, which means they are not cancerous and do not spread to other areas of the body (metastasize).
What causes a giant cell tumor of tendon sheath?
As is true for most soft-tissue tumors, the etiology of giant cell tumors of the tendon sheath is unknown. Pathogenetic theories have included trauma, disturbed lipid metabolism, osteoclastic proliferation, infection, vascular disturbances, immune mechanisms, inflammation, neoplasia, and metabolic disturbances.
What causes giant cell tumors in the hand?
What causes giant cell tumors? While the exact cause of giant cell tumors remains unknown. In some cases, they have been linked to Paget disease of bone. This is a chronic bone disorder in which bones become enlarged and misshapen.
Is giant cell tumor of tendon sheath painful?
Giant cell tumors of the tendon sheath often do not cause pain at first. As the tumor grows larger, symptoms may include the following: Lump at the tumor site. Swelling and pain.
Can giant cell tumors be malignant?
The term malignant giant cell tumor has been used in soft tissues to describe a tumor with a mixture of benign giant cells and malignant mononuclear cells. This has been considered to be a type of malignant fibrous histiocytoma and probably not related to true benign giant cell tumors of soft tissue.
How fast does a giant cell tumor grow?
Giant cell tumor of bone (GCTB) in skeletally immature patients is rare, and little is known regarding how fast GCTB can grow. We report a case of a 10-year-old skeletally immature girl with pathologically proven GCTB with obvious growth plate invasion that showed surprisingly rapid growth over only 14 days.
How rare is a giant cell tumor?
Giant cell tumors usually occur in young adults, and are slightly more common in females. They are quite rare, occurring in only about one out of every one million people per year. Although giant cell tumors are not cancerous, they are aggressive and can destroy the surrounding bone.
Is giant cell tumor painful?
The most common symptom of a giant cell tumor is pain in the area of the tumor. The patient may also have pain with movement of the nearby joint. This pain usually increases with activity and decreases with rest. The pain is usually mild at first, but gets worse over time as the tumor increases in size.
What happens if the tendon sheath bursts?
If this happens, the damage to your tendon may become permanent. Permanent damage may impact the joint. Over time, the joint may become stiff, and your motion may be limited.
What percentage of giant cell tumor is malignant?
Of the 35 cases reviewed, 17 were found to be malignancies in giant cell tumors. These cases accounted for 1.8% of the 924 cases of giant cell tumor that were documented at our institution. Malignancies in giant cell tumors of bone were classified as primary or secondary according to Hutter et al.
How quickly do giant cell tumors grow?
