title: [Severe necrotic and haemorrhagic edema of the upper limbs revealing remitting seronegative symmetrical synovitis with pitting edema].
abstract: BACKGROUND
  RS3PE (Remitting Seronegative Symmetrical Synovitis with Pitting Edema) syndrome is characterized by bilateral and symmetrical tenosynovitis of the distal extremities. It occurs with acute onset in older patients aged over 50 years. This heterogeneous entity can be isolated or can reveal various rheumatic diseases and neoplastic conditions. We report a case of RS3PE syndrome associated with unusually severe cutaneous necrotic and haemorrhagic lesions, and revealing malignant monoclonal IgM proliferation.
  
  
  METHODS
  A 62-year-old man was admitted for acute and symmetrical synovitis of both hands and forearms associated with fever and increased acute phase reactants. Severe necrotic and haemorrhagic edema developed simultaneously. Laboratory tests ruled out infectious disease and collagen vascular disorder. Clinical symptoms responded promptly to corticosteroids to reveal severe erosive arthropathy of both wrists. The monoclonal IgM proliferation discovered during the acute phase evolved into a malignant medullary plasmocytosis. After adequate treatment of this proliferation, no haematological, cutaneous or articular relapse occurred during the two-year follow-up period.
  
  
  CONCLUSIONS
  This type of cutaneous symptoms has never been reported during the course of RS3PE syndrome. It may be supposed that the severity of the initial clinical picture was linked in this patient to the paraneoplastic nature of this.
