Abstrakt

Oncocytic Schneiderian Papilloma (OSP) is one of the three morphologically distinct tumors that arise from Schneiderian membrane (the others include exophytic papilloma and inverted papilloma). The authors describe an OSP originating in the region of frontal sinus, which, to the best of their knowledge, represents the first documented example in English literature of OSP developing in this anatomical site.
