BACKGROUND Benign nasal and paranasal sinus masses are commonly encountered in clinical practice. Though benign, certain nasal polyps, fungal sinusitis, hemangiomas and fibro-osseous tumors can present with locally destructive features and deformities, mimicking malignancies at once. OBJECTIVE This study was carried out to recognize the great variety of benign nasal lesions and their frequenc...

BACKGROUND The association between diabetes and paranasal sinus disease has not been thoroughly investigated. METHODS We cross-sectionally investigated the association between diabetes and the presence of paranasal sinus disease, which was confirmed by a head MRI scan in 1350 adults who underwent a health screening program focusing on brain diseases and metabolic syndrome. Logistic regression...

Malignant tumors of the sinuses and nasal cavity are rare diseases. Squamous cell carcinoma is most common histological type (55–70 % cavity). The frequency neuroendocrine reaches 5 %. Currently, there no generally accepted standard for treatment sinonasal localization. If surgical associated with a significant deterioration quality life or poor outcomes, chemoradiotherapy can be recommended. T...

Peripheral Primitive Neuroectodermal Tumours (pPNET) are rare aggressive tumours of neural crest cell origin. These tumours are more common in children and young adults. This is a unique report of one such presentation in a 23-year-old lady occurring in the left side posterior maxilla and Paranasal sinuses along with imaging characteristics, histopathologic features, immunohistochemical aspects...

Introduction: Ewing sarcoma (ES), which is described as diffuse endothelioma of the bone, is divided into osseous and extraosseous Ewing sarcoma (EES) mostly affecting children and adolescents. It is a rare, aggressive, and poorly differentiated small blue round cell tumor that seldom affects the head and neck regions.   Case Report: Herein, we reported a 46-year-old ma...

the paranasal sinuses are known to be a rare location for metastasis. renal cell carcinoma (rcc) is the most frequent primary tumor to metastasize to the sinonasal region, followed by lung and breast cancer. in particular, clear cell type rcc, which represents approximately 85% of rccs, is characterized by early metastasis, and it sometimes spreads to unusual sites (1, 2). metastatic tumors in ...

purpose : to report a patient with sphenoid sinus mucocele (ssm) case report : the patient is a 19-year-old man who was referred to khatam-al-anbia eye center as retrobulbar optic neuritis. brain and orbital ct scan and mri revealed ssm. the patient underwent endoscopic sinus surgery and visual acuity (va) improved from no light perception (nlp) to 2 meter counting fingers. conclusion : ssm may...

Paranasal sinus malignancies are exceedingly rare. Chronic respiratory tract infections, nasal congestive symptoms and rhinosinusitis are much more prevalent in recent days and manifest many symptoms that overlap with those of sinus malignancy. Symptoms may be nonspecific and indolent for months or even years, leading to delay in diagnosis and consequent advanced diseased stage at presentation....

INTRODUCTION Anatomic variations of the paranasal sinuses are very common. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extens...
