[Endonasal rhinosporidiosis (apropos of 2 cases observed in Gabon)].

Being endemic in India and Sri Lanka, rhinosporidiosis is not much known in Africa where only few cases have been reported for the last 20 years. It is a chronic mycosis striking electively two target zones: nasal and conjunctival mucosae. Many features are still unknown about this pathogenic agent which belongs to the group of phycomycetes. But it has never been yet possible to cultivate it nor to inoculate it to animals. It has a cyclic development, well described by Ashworth. Its treatment is both surgical and medical (fungicides).
