Sinonasal neoplasms again

Sinonasal neoplasms are uncommon neoplasms, accounting for only 1% of all malignancies and only 3% to 5% of all head and neck malignancies. In 2010 Rhinology published the European position paper on endoscopic management of tumours of the nose, paranasal sinuses and skull base (1). This issue of Rhinology again contains interesting new data on tumours in the nose and sinuses and raised my interest in potential role of external (occupational) factors that may influence the pathophysiology of sinonasal disease
