Childhood sarcoidosis manifesting as juvenile rheumatoid arthritis.

Sarcoidosis in childhood may manifest primarily as arthropathy and uveitis, mimicking juvenile rheumatoid arthritis. The characteristic appearance and course of the inflammation at these sites, particularly the uveitis, is often a major clue to correct diagnosis. These children generally do not have the fulminant systemic manifestations such as pulmonary disease usually ascribed to sarcoidosis.
