A Rare Case of Isolated Nasal Neurofibroma Mimicking Sinonasal Polyp
Neurofibromas are benign peripheral nerve sheath tumors which originate from Schwann cells. They are known to occur in extremities as a local manifestation of Von Recklinghausen’s disease i.e. type 1 neurofibromatosis, but isolated neurofibroma occurring in the nasal cavity is a rare entity. Here we report one such case in a 60 year old lady who, presented to us with complaints of difficulty in...
متن کاملAngiomatous Nasal Polyp: A Condition Difficult to Diagnose
Introduction: Angiectatic nasal polyp (ANP) is a rare entity of inflammatory sinonasal polyp, constituting 4 to 5% of all nasal polyps.1 An angiomatous polyp originates from a sinochoanal polyp, either an antrochoanal or a sphenochoanal polyp.

Though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma. Aetiology is multifactorial and is mainl...
متن کاملSinonasal Delivery of Resveratrol via Mucoadhesive Nanostructured Microparticles in a Nasal Polyp Mouse Model
Resveratrol (RSV) has been shown to effectively suppress chronic rhinosinusitis with nasal polyps in a mouse model; however, when locally administered to the sinonasal cavity, bolus RSV is limited by low drug bioavailability owing to its low aqueous solubility and relatively rapid clearance from the administration site. To address this limitation, we propose mucoadhesive nanostructured micropar...
