title: Unusual Eruptions Associated with Mycoplasma pneumoniae Respiratory Infections: Review of the Literature.
abstract: BACKGROUND
  Maculopapular or urticarial eruptions and erythema multiforme sometimes occur in patients affected with Mycoplasma pneumoniae respiratory infections. Further eruptions have also been reported.
  
  
  OBJECTIVE
  To review the literature addressing M. pneumoniae respiratory infection and rather unusual eruptions.
  
  
  METHODS
  Computer-based search in the U.S. National Library of Medicine database as well as in the search engine Google.
  
  
  RESULTS
  We found a possible relationship between M. pneumoniae infection and Fuchs' syndrome (n = 37), varicella-like eruptions (n = 8), Henoch-Schönlein syndrome and further leukocytoclastic vasculitides (n = 21) and erythema nodosum (n = 11). A temporal relationship was also observed with 2 cases of Gianotti-Crosti syndrome. Finally, there exists reasonable evidence that pityriasis rosea Gibert and pityriasis lichenoides et varioliformis acuta Mucha-Habermann are not associated with Mycoplasma infections.
  
  
  CONCLUSIONS
  This review implies that M. pneumoniae may cause, in addition to erythematous maculopapular (or urticarial) eruptions and erythema multiforme, Fuchs' syndrome and varicella-like eruptions. Furthermore, there is an intriguing link with leukocytoclastic vasculitides or erythema nodosum that deserves further investigation.
