Reply To: Possible location for tenosynovial giant cell tumor

Hi, Steve.
As I know, the inner layer of joint capsule, bursa, and tendon sheath have synovium.
But since extensor tendon do not have tendon sheath and consequently, they do not have synovium,
how can they have the potential to develope a GCT?
Thank you, Steve.
