title: Comparison of the manifestations of acute sarcoid arthritis with and without erythema nodosum. Immunopathogenic significance.
abstract: This retrospective study deals with the clinical, radiological and biological data of 16 patients suffering from sarcoid arthritis with (n = 11) and without (n = 5) erythema nodosum (EN). The average age and sex distribution were the same and we failed to demonstrate any significant difference between the two groups. However, it is worth noting that the average number of the joints affected was less in a patient with (3.0) than in a patient without EN (4.8) and that persistence of polyalgias was associated with EN. Nevertheless, one may assume that the current series corroborates the common immunological pathophysiology of these two pictures of sarcoid arthritis.
