Comparative Study
Sarcoid arthritis in a North American Caucasian population.
Thirty-two of 150 Caucasian patients (21%) with sarcoidosis studied had articular symptoms. Twenty-one had acute sarcoid arthritis with bilateral ankle arthritis/periarthritis. Joint symptoms resolved within 4 months and none developed chronic arthropathy or progressive systemic sarcoidosis. ⋯ Acute sarcoid arthritis confers a favorable prognosis in North American Caucasians. Differences from previous American series likely reflects the racial compositions of the population studied. Sarcoid arthritis less often evolves during the course of chronic systemic sarcoidosis and even then rarely progresses to a chronic arthropathy.
