Rhinoscleroma mimicking nasal polyposis.

Rhinoscleroma is increasing in incidence in the United States. It should be considered in patients who are immigrants from endemic countries and present with nasal polyposis that exhibits significant adherence to the nasal septum and relative sparing of the sinuses. Fluoroquinolones are emerging as the adjunctive antibiotic treatment of choice to complement surgical extirpation of the disease.
