title: Eosinophilic fasciitis associated with L-tryptophan ingestion.
abstract: OBJECTIVE
  To present the first case of eosinophilic fasciitis associated with L-tryptophan ingestion.
  
  
  METHODS
  A 23-year-old Australian man developed myalgia and weakness, and later the clinical features of eosinophilic fasciitis, while taking L-tryptophan.
  
  
  RESULTS
  The amino acid supplementation was discontinued and he was treated with prednisone (30 mg/day) for six weeks with significant improvement.
  
  
  CONCLUSIONS
  In sclerodermatous skin diseases, such as eosinophilic fasciitis, the possibility of ingestion of tryptophan-containing products should be considered.
