[Spheno-ethmoidal rhinoscleroma. Report of a case and review of the literature].

We report an unusual case of spheno-ethmoidal rhinoscleroma. This chronic granulomatous disease occurs sporadically in Western Europe. Culture is necessary for diagnosis showing the causative organism of rhinoscleroma, Klebsiella rhinoscleromatis. Immunocytochemistry is used in any suspicious case with a negative culture. Antibiotics are the mainstay of therapy for several weeks, using ciprofloxacine or rifampicin, until the nasal biopsies demonstrated no Klebsiella organism.
