title: [Furuncular myiasis caused by Dermatobia hominis. Fortuitous diagnosis on extemporaneous macroscopic analysis of an excised cutaneous nodule].
abstract: BACKGROUND
  Furuncular myiasis is a parasitic disease caused by the development of human botfly larva in the skin. It affects people living in tropical countries and travelers returning from these countries and concerns a number of medical specialties. One form of treatment involves surgical extraction of the parasites.
  
  
  METHODS
  We report the case of a 47-year-old man returning from Guyana presenting two furuncle-like nodules of the skin on the right buttock and on the right shoulder blade. Extemporaneous intraoperative macroscopic examination of the buttock nodule resulted in diagnosis of myiasis caused by the human botfly, Dermatobia hominis.
  
  
  CONCLUSIONS
  The diagnosis of furuncular myiasis is made primarily on clinical grounds and should be suspected on observation of an abscess in subjects returning from a tropical region. It is consequently rare to find D. hominis in biopsy specimens. In the present case, macroscopic examination showed an extremely rare image of the edge of the intact larva in a longitudinal cut, which to our knowledge has never been published to date.
