ten cases of synovial cell sarcoma are reported. the youngest patient was a 2'a years old boy with synovial cell sarcoma of the knee and the oldest one was a man with synovial cell sarcoma of the elbow.

the objective was to investigate the presence of mycoplasma and chlamydia in the synovial fluid of patients with rheumatoid arthritis (ra) and other chronic arthritides. samples of synovial fluid (sf) were collected from all patients presenting with an articular effusion. seventy sf samples were subjected to study for mycoplasma and cultured on standard media for mycoplasma. the 70 other sf sam...

Synovial sarcomas are soft tissue neoplasms mostly located in the lower extremities of young adults. A case of synovial sarcoma of the thigh in a 35-year-old male with the predominant epithelial component is reported. Microscopically the tumor showed variable-sized well-differentiated glands lined by the cuboidal cells with small foci of spindle cell component between glandular structures...

cutaneous metaplastic synovial cyst (cmsc), presents as a solitary, tender subcutaneous nodule that usually occurs at the site of previous surgery or trauma. histologically, the lesion is characterized by a cystic structure with villous-like projections that lined by metaplastic synovial tissue. the main cause remains unclear, but trauma is presumed to be a precipitating factor, as most reporte...

The objective of this study was to evaluate the effect of through-and-through joint lavage on systemic and synovial serum amyloid A (SAA), total protein, nucleated cell count and percentage of neutrophils in the synovial fluid of six healthy horses. A prospective experimental study was performed where one healthy tarsocrural joint of each horse was randomly assigned to receive repeated through-...

Although synovial cell sarcoma is reported to be the most common neoplasm of the canine synovium, this retrospective study of 35 canine synovial tumors found that the majority were of histiocytic origin. Five (14.3%) synovial cell sarcomas were identified by positive immunohistochemical staining with antibodies to cytokeratin. Eighteen (51.4%) histiocytic sarcomas were identified by cell morpho...

Synovial T cells in rheumatoid arthritis are highly differentiated and express a phenotype suggesting susceptibility to apoptosis (CD45RB dull, CD45RO bright, Bcl-2 low, Bax high, Fas high). However, no evidence of T cell apoptosis was found in synovial fluid from any of 28 patients studied. In contrast, synovial fluid from 10 patients with crystal arthritis showed substantial levels of T cell ...

Abstract T lymphocytes, synovial macrophages, and synovial fibroblasts are the three most abundant cell populations in rheumatoid arthritis synovial tissue, and each is believed to play an important role in the pathogenesis of joint inflammation and destruction. While interactions between T cells and macrophages and between macrophages and fibroblasts have been carefully studied, less attention...

The present study was performed to clarify the relationship between human T cell lymphotropic virus type I (HTLV-I) infection and chronic inflammatory arthropathy. To determine the ability of HTLV-I to infect synovial cells and the effect on synovial cell proliferation, synovial cells were cocultured with the HTLV-I-producing T cell lines (MT-2 or HCT-1). After coculture with HTLV-I-infected T ...

OBJECTIVE The effects were studied of interleukin 4 (IL-4) on T cell-synovial cell adhesion and on the expression of adhesion molecules on the surface of synovial fibroblast-like cells. METHODS The adhesion of T cells toward the synovial cells were measured by 51chromium-labelled adhesion assay. The expression of adhesion molecules on synovial cells were analysed by flowcytometry. RESULTS S...
