Whilst it has a malignant potential it rarely transforms and in its benign form the main concern originates from its locally aggressive nature and substantial propensity to recur. Bilateral disease can also be due to inverted papilloma, sometimes due to direct extension of the tumour, but it can also occur as two distinct lesions. Here we report two cases of bilateral involvement, review the current literature and highlight some important issues on the management and follow-up of this well known neoplasm.
