Abstract

Inverted papillomas are relatively rare, benign tumors of the sinonasal cavity that generate interest to many clinicians because of their high rate of recurrences, locally invasive character and malignant transformation. The incidence of bilateral occurrence, ranging from 2 to 7%, is extremely rare, and the incidence of synchronous malignancy is also rare too. Here, we report an unusual case of bilateral inverted papilloma with a malignant transformation on one side. We compared the expression of molecules that suggested a relation with malignant transformation in inverted papilloma between each side of the tumors.
