Tenosynovial Giant Cell Tumor


As per the definition goes, Tenosynovial giant cell tumor (TGCT) is a group of rare tumors that form in the joints. TGCT is not typically cancerous, but it can grow and damage surrounding structures.


What are places Tenosynovial Giant cell tumor can happen?


There are some very common places where you can get the condition. These are the joints that get affected:

1) Synovium: These are actually the thin layer of tissue that lines the inner joint surfaces.

2) Bursae: These are the cushion tendons and muscles around the joint. They are used to prevent friction.

3) Tendon sheath: It is the layer of tissue around tendons.


Kinds of Tenosynovial Giant cell tumor


The types of Tenosynovial giant cell tumor is based on the place. It is on the basis of how the tumor mass grows and is localized.


a) Giant cell tumors of the tendon sheath (GCTTS): It is called so when actually growing in the smaller joints like the hands. These have much slower growth.


b)Pigmented villonodular synovitis (PVNS): It is diffusing giant cell tumors grow quickly and affect large joints like the knee, hip, ankle, shoulder, or elbow.


Both of them might not grow cancerous, however, they affect structures around them. The degeneration of those might cause cancer to develop.


What are the Reasons for the Tenosynovial giant cell tumor?


TGCTs are caused by changes that happen in the chromosome, called a translocation. Pieces of a chromosome break off and change places. It isn’t clear what causes these translocations.

What is a Chromosome? Chromosomes contain the genetic code for producing proteins. The translocation leads to the excess production of a protein called colony-stimulating factor 1 (CSF1).

This protein is to bring cells that have CSF1 receptors on their surface. They are also including white blood cells called macrophages. These cells clump together until they eventually form a tumor.


Signs of Tenosynovial giant cell tumor


There are some specific symptoms you must look for when you are deciding about the condition. In case you see these happening, go to a doctor.

A nuclear imaging test used to detect bone diseases and tumors and to determine the cause of bone pain or inflammation.
