The specific relationship between sinonasal polyps and sinonasal malignancies has not been well described. With regard to allergic etiologies, there is some suggestion that those individuals with atopy in general may be at higher risk of lymphoma.1,2 One population-based study demonstrated an association with allergic rhinitis and nasopharyngeal carcinoma.3 Another study evaluated 22 patients with newly diagnosed nasopharyngeal carcinoma, 4.5% of whom had allergic rhinitis.
