title: Arthritis in sarcoidosis.
abstract: OBJECTIVE
  Sarcoidosis is systemic granulomatous disorder. Articular manifestations have received little attention in the literature. Case records of patients with sarcoidosis, presenting with articular symptoms between 1990-1999, were retrospectively analysed.
  
  
  RESULTS
  Twenty nine patients, 15 males and 14 females, median age 44 years (range 15-67 years) and median duration of articular symptoms of eight months diagnosed clinically (n=9) and on biopsy (n=20) were studied. Twenty five patients had arthritis as the presenting manifestation. Fifteen patients had chronic arthritis (> six months). Lofgren's syndrome was seen in 7% of the patients. Acute arthritis was episodic (n=4), more common in males (M:F = 9:5), predominantly affected lower limb joints and mimicked reactive arthritis. Chronic arthritis was more frequently observed in females (M:F = 1:2) and presented with involvement of bilateral symmetric hand joints, mimicking rheumatoid arthritis. Extra-articular manifestations like neuropathy and constitutional symptoms were observed in acute arthritis. Skin plaque, splenomegaly and interstitial lung disease were seen with chronic arthritis. At a median follow up of 12 months, 10/14 and 5/15 achieved complete remission whereas 2/14 and 9/15 achieved partial remission of the articular symptoms in the acute and chronic groups, respectively.
  
  
  CONCLUSIONS
  Arthritis in sarcoidosis is an early manifestation of disease and may mimic reactive or rheumatoid arthritis. Unsatisfactory response in chronic arthritis highlights the need for immunosuppressive drugs in addition to steroids.
