Migratory Polyarthritis: Clinical Presentation and Characteristics

Key Clinical Features

Migratory polyarthritis typically presents as joint pain and swelling that moves from one joint to another over time, most commonly affecting large joints such as knees, ankles, elbows, and wrists, with rapid response to anti-inflammatory medications being characteristic 1, 2
The American Heart Association notes that migratory pattern: Pain and swelling move from one joint to another, with previous joints improving as new joints become affected 1, 2
The American College of Cardiology recommends consideration of predominant involvement of large joints (knees, ankles, elbows, wrists) 1, 2
Migratory polyarthritis has a self-limited course, typically lasting approximately 4 weeks even without therapy, as stated by the American Heart Association 1
Rapid improvement with salicylates or nonsteroidal anti-inflammatory drugs (NSAIDs) is characteristic, according to the American College of Cardiology 1
The American Heart Association notes the absence of long-term joint deformity 2
Less common involvement of small joints of hands, feet, and spine compared to other arthritic conditions is observed, as stated by the American College of Cardiology 2

Acute Rheumatic Fever (ARF) is a classic cause of migratory polyarthritis, especially in moderate to high-risk populations, according to the American Heart Association 1, 2
The American Academy of Pediatrics notes that ARF follows group A β-hemolytic streptococcal infection 3
The American Heart Association recommends consideration of other manifestations (carditis, chorea, erythema marginatum, subcutaneous nodules) that often accompany ARF 3
Morning stiffness may be present but is typically mild and brief, as stated by the American Academy of Pediatrics 3
Post-Streptococcal Reactive Arthritis may not fulfill all Jones criteria, according to the American College of Cardiology 2
The Centers for Disease Control and Prevention notes that Lyme disease can present with migratory joint pain and swelling, often preceded by erythema migrans rash in 60-80% of cases 4
History of tick exposure in endemic areas is common, as stated by the Centers for Disease Control and Prevention 4

Inflammatory arthritides (rheumatoid arthritis, psoriatic arthritis) should be considered in the differential diagnosis, according to the American Society of Clinical Oncology 5
Crystal arthropathies (gout, pseudogout) are also part of the differential diagnosis, as stated by the American Society of Clinical Oncology 5
Septic arthritis (requires urgent exclusion) is a critical consideration, according to the American Society of Clinical Oncology 5
Immune checkpoint inhibitor-induced arthritis is a potential diagnosis, as noted by the American Society of Clinical Oncology 6
