Diffuse Connective Tissue Diseases
Diffuse connective tissue disease refers to a group of disorders that are chronic in nature and characterized by diffuse inflam-mation and degeneration in the connective tissues. These disor-ders share similar clinical features and may affect some of the same organs. The characteristic clinical course is one of exacer-bations and remissions. Although the diffuse connective tissue diseases have unknown causes, they are thought to be the result of immunologic abnormalities. They include RA, SLE, sclero-derma, polymyositis, and polymyalgia rheumatica.
