GCT & PVNS (Giant Cell Tumor of Tendon Sheath & Pigmented Villonodular Synovitis) 101 (video)

Tenosynovial giant cell tumors exist on a spectrum and present in one of two forms: either a small circumscribed nodule usually on the hand/finger (the localized form, also known as giant cell tumor of tendon sheath) or as a larger more infiltrative mass usually in the knee (the diffuse form, also known as pigmented villonodular synovitis (PVNS) when it involves the articular space of the joint). These tumors are usually easy to diagnose, even when giant cells are scarce or absent, provided you know the other diagnostic features. This video shows you how.
