Diffuse type tenosynovial giant cell tumor (D-TGCT) is a locally aggressive benign proliferation. Knee joint the most commonly affected site. We present case report with 16 months follow up after recurrent surgery and postoperative radiotherapy.

There was no history of joint problems, infection or bowel problems, nor was there a family history of arthritis. Physical exa...

This paper reports a case of diffuse pigmented villonodular synovitis (DPVNS), associated with advanced gonarthrosis, submitted to total knee replacement. The patient had progressive pain and swelling. She had two previous surgeries, firstly arthroscopic synovectomy and subsequently open synovectomy associated with radiotherapy, with recurrence of the disease. Magnetic resonance imaging reveale...

OBJECTIVE US is a promising tool in evaluating RA synovitis, but abnormal US findings have been reported in small subsets of normal joints in healthy subjects. This study aimed to systematically assess greyscale US (GSUS) and power Doppler US (PDUS) findings in 40 peripheral joints-the 28-joint DAS (DAS28) set, ankles and MTP joints-in healthy subjects. A composite score of abnormal US findings...

The localized form of pigmented villonodular synovitis is characterized by a limited involvement of synovium. Although the knee is the joint that is commonly affected, bone changes in this location are not usual. We report the case of a histologically proven localized form of this entity in the knee, which mimicked a benign bone tumor on the basis of an MR pattern, CT findings, and scintigraphi...

Background: Diffuse pigmented villonodular synovitis (DPVNS) of the knee is a difficult tumor to eradicate, gold standard treatment has traditionally been surgical excision with total synovectomy affected joint, either an open or arthroscopic approach. In this study, we are focusing on synovectomy. Objectives: Aimed study outcome for diffuse in Haj Alsafi Teaching Hospital. Methodology: Observa...

Cryostat section of synovial tissue from patients with rheumatoid arthritis, ankylosing spondylitis, osteoarthrosis, pigmented villonodular synovitis, and from a normal knee were studied by indirect immunofluorescence with guinea-pig antibodies to the intermediate filament proteins prekeratin, vimentin, and desmin. Staining for vimentin, but absence of prekeratin and desmin, was demonstrated in...
