Background: Nasal polyps (NPs) are inflammatory outgrowths of paranasal sinus mucosa that occur in one to four percent of the population and most commonly cause congestion, obstruction, or hyposmia. Intranasal corticosteroids, along with short courses of oral corticosteroids, are most often recommended for symptomatic nasal polyposis, prior to consideration of surgical intervention. We present the first reported case of spontaneous nasal polypectomy, occurring after use of fluticasone propionate (XHANCE®) and zileuton (Xyflo®).
Methods: A 43-year-old Asian-Indian male with history of allergic rhinitis, asthma, and nasal polyposis had been prescribed subcutaneous immunotherapy for five years without effectiveness before another polypectomy was scheduled. After the polyps resurfaced, the patient was prescribed prednisone and underwent another polypectomy. He later presented with persistent NPs and congestion, as well as diffuse lymphadenopathy and pruritic eyes and ears. Fluticasone Propionate was continued as maintenance therapy and Zileuton was prescribed in place of Montelukast (Singulair®).
Results: After several weeks of the new treatment regimen, the patient reported polyp irritation and movement, as well as influenza-like symptoms. Epistaxis soon occurred, followed by a spontaneous polypectomy. Three more polyps were expelled with bloody discharge. The patient reported resolved hyposmia and reduced symptoms thereafter. The treatment regimen was continued without change or further episodes of epistaxis and polypectomy.
Conclusion: Few case reports in the literature describe polyp autoamputation. We report the first instance of spontaneous nasal polypectomy in the literature, induced by Fluticasone Propionate and Zileuton.
