Abstract
Even though the diagnostics of rheumatic joint diseases are mostly based on clinical, immunoserological and imaging criteria, histopathology can also make a significant contribution. This is particularly true for clinically unclear monoarticular and periarticular diseases. The contribution of histopathology to the diagnosis of rheumatic diseases is manifold since the histopathological differential diagnosis includes the complete spectrum of synovial diseases. This heterogeneous pathogenetic spectrum is described in the joint pathology algorithm, which includes inflammatory and non-inflammatory diseases. To the latter group belong certain benign tumors such as the diffuse variant of the tenosynovial giant cell tumor, lipoma, hemangioma, vascular malformations and synovial chondromatosis. Additionally, the rare group of storage diseases should be kept in mind. Inflammatory diseases can be discriminated into crystal-induced arthropathies mainly such as gout and pseudogout, into granulomatous diseases such as tuberculosis and foreign-body inoculations, and finally into the large group of non-granulomatous, non-infectious synovitis. This large group is by far the most common, and it often causes difficulties in assigning the histopathological findings to a concrete rheumatologic diagnosis. In this context the synovitis score should be applied as a diagnostic device in these cases, leading to the diagnosis of a low-grade synovitis (which is associated with degenerative arthropathies) or of a high-grade synovitis (associated with rheumatic diseases). Identification of crystals and crystal-like deposits should be carried out with the application of the joint particle algorithm which addresses the identification of endogenous and non-endogenous particle deposits in the synovial tissues. Additionally, the synovitis-score may be used for evaluation of arthritis-progresssion and for the evaluation of inflammation-regression as a consequence of therapy with biologicals.
