Abstract
Inverted papilloma (IP) is a locally destructive, benign neoplasm of the nose and paranasal sinuses with a high tendency for recurrence, a significant potential for malignancy, and an etiology that today is still uncertain. The expression of hormonal receptors in neoplastic tissues has been the focus of intensive research for its potential diagnostic, prognostic, and therapeutic significance. The aim of this study was to assess the potential estroprogestinic receptor expression in patients undergoing sinus surgery for IP. A retrospective study was carried out, on surgical specimens of 73 patients who underwent endoscopic sinus surgery for first manifestation of sinonasal IP (primitive IP group) and in 21 subjects who had developed a recurrence (relapsed IP group). The results of the immunohistochemical analysis of the first group showed the absence of receptor expression for PGR in all cases analyzed and the presence of a low positivity for ER in 11 cases (P > 0.082). Similarly, in the second group the results showed a low presence of ER receptors in 3 of the 21 cases (P > 0.068), while there was no evidence of PGR receptors in the examined samples. In addition, in 11 of the cases only 3 were considered positive (27.2%) showing a recurrence during follow-up (P > 0.068). Our results suggest that the sinonasal IP is a benign tumor independent of estrogen and progesterone, and the receptors for these hormones are therefore unsuitable as predictors of relapse or possible prognostic indicators and therapeutic targets.

Abstract
Sinonasal inverted papillomas are well known for high recurrence rates after surgery and the risk of malignant change. Recurrent disease occurs because of inadequate excision as a result of poor exposure and visualization. For these reasons, aggressive surgery has been advocated-classically a lateral rhinotomy and en bloc medial maxillectomy. Endoscopic techniques have provided excellent visualization and a less invasive approach to these tumours. We describe 18 patients with inverted papillomas treated endoscopically at the Singapore General Hospital since 1993. The presentation, sites of involvement and diagnostic imaging are presented. All the patients had a minimum follow-up of 18 months with a mean of 32.8 months. One case of recurrence at the frontal recess is reported. Endoscopic management is appropriate for the diagnosis, follow-up and treatment of circumscribed primary and recurrent inverted papillomas.
