Introduction: The examination of the synovial is very useful in the positive and differential diagnostic of many articular diseases and especially in the conditions of acute monoarthritis.
Materials and methods: The study focused on the establishment of clinical-statistical, histopathological and immunohistochemical correlations on a group of cases anatomo-pathologic diagnosed with synovity with articular inflammatory liquid. The group was divided in five subgroups: rheumatoid polyarthritis, uric arthropathy (gout), TBC arthritis, sarcoidosis and villo-nodular synovity.
Results and discussion: During the clinical-statistical study the number of arthritis with articular inflammatory infiltration was pursued, the specific location of them and the correlation of the clinical dates with paraclinical ones. In the histopatological and immunohistochemical analysis was pursued the presence of the inflammatory infiltration through the implication of both types of B- and T-lymphocytes in different proportions taking into consideration the cause of the synovity.
Conclusions: The synovial biopsy is indicated at patients at whom the diagnostic is not established after the clinical evaluation. The examination of the synovial tissue can be the only way of establishing a definitive diagnostic in inflammatory arthropathies.
