Schwannomas are neurogenic tumors arising from the Schwann cells present in neural sheath of myelinated nerves. These benign that can arise anywhere body. rarely seen nose and paranasal sinuses representing <4% all head-and-neck schwannomas. Surgical excision is treatment choice these cases. Nasal polyps common nasal cavity lesions which usually inflammatory polyps. Schwannoma presented with...

Nasal dermoplasty for recurrent polyps (NDRP) is a new technique for the surgical treatment of this condition. Churg-Strauss syndrome is characterized by the presence of nasal polyps with a great tendency for relapse after surgical or pharmaceutical treatment. It is the first time that we use NDRP to treat nasal polyps in a patient with Churg-Strauss syndrome. The patient was a 33-year-old fema...

Antrochoanal polyps are benign lesions originating from the mucosa of the maxillary sinus. Nasal obstruction and rhinorrhea are their main symptoms. Their endoscopical and radiological appearance makes them relatively easy to diagnose. These polyps are usually presented unilaterally, although bilateral presentation is also possible. We described two cases of atypically giant antrochoanal polyps...

Introduction. Antrochoanal polyps (ACPs) occur most commonly in children and young adults. Antrochoanal polyps are associated with chronic sinusitis and/or allergy. The symptoms of ACPs are nasal obstruction, rhinorrhea, headaches and post-nasal drip. The treatment of choice is surgical. Material and methods. In the study we analyzed the clinical data of 19 children with antrochoanal polyps who...

INTRODUCTION The pathogenesis of nasal polyps is still not fully understood. AIM To analyze the topography and intensity of interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), cyclooxygenase 2 (COX-2), nitric oxide synthase 2 (NOS-2), and nuclear factor-κB (NF-κB) expressions in eosinophilic and neutrophilic polyps and in normal nasal mucosa. MATERIAL AND METHODS The study included spe...

Airway inflammation in patients with nasal polyps is characterized by the increased presence of eosinophils, the numbers of which are reduced after treatment with topical corticosteroids. Because eosinophilic responses in the airways are in part due to eosinophil progenitor differentiation, we hypothesized that CD34, a cell surface, sialomucinlike glycoprotein that specifically marks hemopoieti...

Introduction: Nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. 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...

Chronic rhinosinusitis with nasal polyps (CRSwNP) in Caucasians is a chronic Th2 inflammatory disease of the nasal and paranasal mucosa and the recruitment of leukocytes to the site of inflammation is poorly understood. We studied mRNA and protein expression profiles of adhesion molecules in nasal polyp and associated inferior turbinate tissues using molecular, biochemical, and immunohistologic...

BACKGROUND Nasal polyposis has different etiologies in Western and Eastern countries. Furthermore, its pathogenesis is still poorly understood. OBJECTIVE To determine the T-cell phenotypes involved in nasal polyposis in Chinese patients. METHODS Twenty-four Chinese patients with nasal polyps were studied. CD4, CD8, Foxp3, and interleukin (IL) 17 were analyzed by immunohistochemical staining...
