Typically, rhinoscleroma appears in patients aged 10-30 years.
It is endemic to poor regions of Africa (Egypt, tropical areas), Southeast Asia, Mexico, Central and South America, and Central and Eastern Europe, but it has been infrequent in the United States.
Rhinoscleroma tends to affect females somewhat more often than it does males.
Patients of all races can be affected.
