Sarcoidosis--the way ahead.

The cause(s) of sarcoidosis is likely to be a combination of a conducive soil or sarcoid diathesis invaded by an antigen-driven cell-mediated immune response. The antigenic invasion may be mycobacteria and other organisms and/or their chemical constituents. A ten-point plan of management is set out so that early diagnosis allows early treatment and to prevent complicating pulmonary, ocular or renal fibrosis and to prevent failure of these vital organs.
