Chronic sarcoid arthritis.

Sarcoidosis can involve almost any organ or tissue. The outcome may be clinical recovery with radiographic evidence of residua, impairment of function of organs involved, or a continued chronic course. This report is a patient who presented with chronic sarcoid arthritis without evidence of active disease in other organs, 20 years after sarcoidosis had been diagnosed. The clinical picture superficially resembled rheumatoid disease with keratoconjunctivitis sicca and basal lung fibrosis.
