title: Economical microscope configuration for direct mycological examination with fluorescence in dermatology.
abstract: BACKGROUND
  The use of fluorochromes such as Blankophor or Calcofluor allows to detect immediately and without ambiguity fungal elements in dermatological preparations. Whereas fluorescence microscopy is widely practised in clinical laboratories, it is not generally used in private practice because of the high price of a epifluorescence microscope.
  
  
  OBJECTIVE
  To propose an economical microscope configuration to visualize fungal elements using fluorescence.
  
  
  METHODS
  The preparations were examined with a standard microscope for routine observations, equipped with only two supplementary filters.
  
  
  RESULTS
  Because the fungal elements produce a particularly bright fluorescence, a 25-watt halogen light is sufficient to visualize them in dermatological preparations:
  
  
  CONCLUSIONS
  The proposed microscope configuration for direct mycological examination is particularly economical since equipment for epifluorescence and a vapour mercury lamp are not necessary.
