title: Epithelial (inverted) papilloma: a correlated radiological--histological study.
abstract: The radiological and pathological features in 14 cases of epithelial papilloma are described. The typical radiological findings are a mass in the nares and sinus opacification, usually on the same side. Occasionally, extension of the mass into the nasopharynx is observed. Bone destruction may be present in epithelial papilloma, possibly due to pressure erosion. In the presence of carcinoma, bone destruction may be due to direct invasion.
