Treatment of Diffuse Tenosynovial Giant Cell Tumor

Diffuse tenosynovial giant cell tumor (D-TGCT) is a locally aggressive form of the disease characterized by multinodular proliferation within large joints. Its tendency for local destruction and recurrence requires a structured surgical approach tailored to the extent of involvement.

Clinical Scenario

D-TGCT forms multiple nodules that proliferate in larger joints — most commonly the knee — and is associated with a significant risk of local tissue destruction. The diffuse pattern distinguishes this presentation from the localized form and informs the choice of surgical strategy.

Treatment Approach (Partial Overview)

The current standard of treatment is surgical. Management centers on total synovectomy of the affected joint, with the specific technique — and whether additional reconstructive intervention is incorporated — determined by disease extent and joint involvement. The complete evidence-based regimen, including procedural selection criteria, is available via the full protocol.

D-TGCT forms multiple nodules that proliferate in the larger joints, such as the knees (75%), and are likely to be locally destructive.
Traditionally, the surgical approach for L-TGCT and D-TGCT involves marginal excision and total synovectomy, respectively.
Another strategy to balance the risk of recurrence with postoperative complications involves the utilization of open posterior with arthroscopic anterior synovectomy compared to the posterior arthroscopic synovectomy approach.
Joint arthroplasty combined with synovectomy can help decrease flexion contractures and improve functioning in patients while ensuring a low recurrence rate.
Surgery is the current standard of treatment.
