Background: Tenosynovial giant cell tumors (TGCTs) or giant cell tumors of tendon sheath are neoplasms that arise in the synovium. They can be categorized as nodular (localized) or diffuse type (D-TGCT). Historically, surgery has been the mainstay of therapy, but diffuse type disease recurs at a high rate and treatment often requires increasingly morbid procedures. Read More

Inconclusive benefit of adjuvant Yttrium hydroxyapatite to radiosynovectomy for diffuse-type tenosynovial giant-cell tumour of the knee.

Bone Joint J 2018 07;100-B(7):984-988

Assuta Ashdod University Hospital, Ashdod, Israel, affiliated to the Beer Sheva Faculty of Medicine, Beer Sheva University, Beer Sheva, Israel.

Aims: Intra-articular Yttrium (Y) is an adjunct to surgical treatment by synovectomy for patients with diffuse-type tenosynovial giant-cell tumour (dtTGCT) of the knee, with variable success rates. Clinical information is, however, sparse and its value remains unclear. We investigated the long-term outcome of patients who underwent synovectomy with and without adjuvant treatment with Yttrium.

Computed Tomography Findings of Pigmented Villonodular Synovitis in a Dog.

Vet Comp Orthop Traumatol 2018 Jul 4;31(4):304-310. Epub 2018 Jun 4.

Institute of Veterinary Science, University of Liverpool plus Institute of Ageing and Chronic Disease, Liverpool, Cheshire, United Kingdom of Great Britain and Northern Ireland.

Pigmented villonodular synovitis (PVNS) is a rare benign and usually monoarticular neoplastic lesion arising from the synovium, bursae and tendon sheaths in humans, horses and dogs. Categorization for PVNS in humans includes localized and diffuse forms of PVNS and tenosynovial giant cell tumour (TGCT), although histologically they are the same. The localized form is characterized by discrete nodular lesions, the diffuse form is often intra-articular, infiltrative, affecting the entire synovium with more aggressive behaviour and TGCT occurs along tendon sheaths.
