Differential Diagnosis for Early Onset Extensive Raynaud Phenomena

Single Most Likely Diagnosis

  • Juvenile Systemic Sclerosis (JSSc): This condition is characterized by early onset of Raynaud's phenomenon, often before the age of 6 months, and is associated with scleroderma. The extensive nature of the Raynaud's phenomenon at such a young age points towards a systemic condition like JSSc.

Other Likely Diagnoses

  • Mixed Connective Tissue Disease (MCTD): This autoimmune disorder can present with features of lupus, scleroderma, and rheumatoid arthritis, including Raynaud's phenomenon. Its onset can be at any age, including infancy.
  • Juvenile Idiopathic Arthritis (JIA): While JIA primarily affects joints, some subtypes can present with systemic features, including vasculitis, which might manifest as Raynaud's phenomenon.

Do Not Miss Diagnoses

  • Eosinophilic Granulomatosis with Polyangiitis (EGPA): Although less common in infants, EGPA can present with a wide range of symptoms, including vasculitis that might cause Raynaud's phenomenon. Given its potential severity, it's crucial not to miss this diagnosis.
  • Kawasaki Disease: This condition primarily affects children and can cause vasculitis, which might lead to symptoms similar to Raynaud's phenomenon. Early diagnosis is critical due to the risk of cardiac complications.

Rare Diagnoses

  • Buerger's Disease: A rare condition characterized by inflammation of small and medium-sized blood vessels, which could potentially cause symptoms similar to Raynaud's phenomenon. However, it's exceedingly rare in infants.
  • Cryoglobulinemic Vasculitis: This condition involves inflammation of blood vessels due to abnormal proteins and can cause a variety of symptoms, including those similar to Raynaud's phenomenon. It's rare and more commonly associated with infections like hepatitis C or autoimmune disorders.
