Previously known as pigmented villonodular synovitis (PVNS) and giant cell tumor of the tendon sheath (GCT-TS), Tenosynovial Giant Cell Tumor (TGCT) is a type of rare, locally aggressive, typically benign, tumor of the joint, tendon sheath, or bursae. TGCT Support is a community open to TGCT patients, their caregivers and family members. It is also open to physicians, researchers, and others interested in learning more about TGCT and helping those with the disease. Joining the community is free! We want to come together to share medical experiences, provide each other with support, and share tools to guide you through your TGCT journey. Most importantly, we are here to ensure that no one faces TGCT alone.
