Case report. The nonspecific rheumatoid subcutaneous nodule: its presence in fibrositis and scleroderma.

"Rheumatoid" subcutaneous nodules that were at one time considered diagnostic of rheumatoid arthritis or rheumatic fever have also been found in individuals withoug known disease, in patients with systemic lupus erythematosus, and in other conditions. In this report, subcutaneous nodules were described in one patient with fibrositis and in another scleroderma. Multiple pathogenic mechanisms are probably responsible for development of these nodules.
