Olfactory neuroblastoma (ONB), which is a neuroectodermal tumor of the nasal cavity, is a rare and locally aggressive malignancy that may invade the orbit via local destruction. In this study, we report a patient with proptosis, external ophthalmoplegia, and compressive optic neuropathy caused by ONB. A detailed clinical examination including ocular imaging and histopathological studies were performed. The 62-year-old female patient presented to our clinic with complaints of proptosis and visual deterioration in the left eye...

A 48-year-old man with a history of birdshot chorioretinitis presented with blurry vision, retro-bulbar pain and sinusitis. Though visual acuity was unaffected, he had left optic disc oedema and mild restriction of left eye abduction. His symptoms progressed quickly, with diplopia in primary gaze, epistaxis from his left nostril, and a left relative afferent pupillary defect (RAPD). On computed tomography, there was a mass in the nasal cavity that extended through the left cribriform plate and lamina papyracea and posteriorly into the optic canal...

Immunoglobulin G4-related disease (IgG4-RD) is becoming increasingly documented. It was first described in relation to autoimmune pancreatitis. Features of the disease include tissue infiltration by IgG4 plasma cells with associated fibrosis and the growth of pseudotumours. A 71-year-old woman presented with increasing right cheek swelling and mild proptosis. Ten years earlier, she had a similar presentation and was diagnosed with an inflammatory pseudotumour. Examination revealed a lesion in the right nasal cavity...

A major functional role of the nasal cavity is air conditioning of the inspired environmental air to near alveolar conditions. It is well known that the anatomical disparities among nasal passages can change airflow patterns to a great extent. However, its effect on nasal air conditioning performance remains largely unexplored. This research investigated the nasal air conditioning performance among nasal models with distinct vestibule phenotypes, including subjects with and without vestibule notches. For the mass transfer, we used a two-film theory model to determine the species transport...

The World Health Organization (WHO) 2017 classification of head and neck tumors has been just published and has reorganized tumors of the nasal cavity and paranasal sinuses. In this classification, three new entities (seromucinous hamartoma, NUT carcinoma, and biphenotypic sinonasal sarcoma) were included, while the total number of tumors has been reduced by excluding tumors if they did not occur exclusively or predominantly in this region. Among these entities, benign tumors were classified as sinonasal papillomas, respiratory epithelial lesions, salivary gland tumors, benign soft tissue tumors, or other tumors...

Glomangiopericytoma is a rare vascular neoplasm characterised by a pattern of prominent perivascular growth with myoid phenotype. It is categorised as a borderline low-malignancy tumour by WHO and accounts for less than 0.5% of all sinonasal tumours. After curative resection, patients of glomangiopericytoma need long-term endoscopic follow-up due to high risk of recurrence.We report a case of a 23-year-old man complaining of nasal obstruction off and on and frequent epistaxis. A reddish mass in the right nasal cavity was observed on endoscopy and treated with endoscopic excision...

OBJECTIVES: During the physiological ageing process atrophy of the alveolar bone appears in vertical direction. This bone resorption causes pushing the limits of the maxillary sinus at the expense of a degraded bone. The sinus volume increases due to the facial development in children and adolescents or during the ageing process due to the loss of teeth and bone mass. The main aim of this study is to determine the sinus shape and sinus floor morphology related to age. MATERIALS AND METHODS: Human adult male and female cadaveric heads (aged 37 to 83 years) with different dental status were used...

INTRODUCTION: Ewing sarcoma (ES) of the sinonasal tract and associated primitive neuroectodermal tumors are rare. To our knowledge, only 10 case reports of sinonasal ES of the nose or paranasal sinuses have been reported. Furthermore, there has been only 1 case of sinonasal ES arising from the middle turbinate. Recommended management of sinonasal ES stems from the management of its osseous counterpart, ES, but treatment with surgery, radiotherapy, and chemotherapy is varied. Five-year survival rates vary from 21% to 70%, with the lower rates representing patients presenting with metastatic disease...

Meningioma originates from arachnoid cap cells and is the second most common intracranial tumor; however, it can also be found in an extracranial location. A very rare primary extracranial meningioma without the presence of an intracranial component has also been reported. Primary extracranial meningiomas have been found in the skin, scalp, middle ear, and nasal cavity. A computerized tomography or magnetic resonance imaging scan is necessary to determine the presence or absence of an intracranial meningioma, and a biopsy is essential for diagnosis...

The most common benign tumour of the major salivary glands is the pleomorphic adenoma. They are seen rarely in the minor salivary glands, usually in hard palate, soft palate and nasopharynx. Pleomorphic adenomas in nasal cavity are unusual and may be misdiagnosed because they have predominant myoepithelial cellularity and fewer myxoid stromata compared with those elsewhere. We present a case of 38-year-old male with a 2-year history of left nasal obstruction and epistaxis since 6 months. Diagnostic nasal endoscopic examination showed a soft lobulated mass in left nasal cavity attached to anterior part of the septum...

A concha bullosa forms when the middle turbinate becomes pneumatized, which is a common anatomic variation; however, fungus ball in concha bullosa is rather rare. An otherwise healthy 52-year-old man presented to our ear, nose and throat clinic with the complaints of midfacial pressure headache and malodorous postnasal drip. Computed tomography of the paranasal sinuses demonstrated a polypoid hyperdense lesion with slight microcalcifications in the right nasal cavity, accompanied with a complicated fluid collection in the right frontoethmoideal recess seen as hypodensity in contrast to this hyperdensity...

A 57 year-old, male presented with a chronic unilateral nasal obstruction and epistaxis. Intranasal endoscopy showed multiple polypoid lesions. The computed tomography exam revealed a heterogeneous mass that occupied the right nasal cavity with osteolysis of the middle and lower cone causing fluid retention of the right maxillary sinus. He underwent resection of these lesions. Pathological examination revealed malignant transformation of nasal inverted papilloma into sarcomatoid carcinoma. This case report highlights the importance of considering malignant transformation in the differential diagnosis of polypoid lesions...

We report a rare case of squamous cell carcinoma (SCC) of the nasal cavity arising in a patient with granulomatosis with polyangiitis (GPA). The patient was a 35-year-old man who had been diagnosed 15 years earlier with GPA and treated medically for sinonasal, pulmonary, and renal involvement. He presented to us with left-sided orbital and cheek pain and nasal obstruction. Endoscopy detected a friable, exophytic mass that involved the left lateral nasal wall and septum. Biopsy analysis identified the mass as an SCC...

Olfactory neuroblastoma is a rare malignant tumor of neuroectodermal origin and represents the most common cancer of the nasal cavity in pediatric age. The gold standard of treatment consists of en bloc resection, numerous studies have shown as the endoscopic approaches permit good control of the disease improving the quality of life after the treatment. Herein we describe the case of a 13-year-old patient referred to our outpatient clinic with a polypoid multi-lobed lesion occupying the left nasal cavity and imaging that confirmed a left-sided nasal mass without cribriform plate involvement (Kadish B)...

Sinonasal mass is the abnormal growth of tissue from nasal cavity and mucosa of the paranasal sinuses. The growth may be benign or malignant. The benign lesion grows slowly and does not metastasize. The malignant lesion grows rapidly and metastasizes early. The aim of this study is to evaluate and diagnose the various types of sinonasal masses with MRI and its correlation with histopathological findings. This cross sectional descriptive study was carried out for a period of 02 years, from July 2015 to June 2017...

A 48-year-old man presented to urgent care with recurrent epistaxis over 6 months. Initially, nosebleeds were controlled with packing or cautery. Ultimately, he was referred to ear, nose and throat department and underwent nasal endoscopy which revealed polypoid tissue. A biopsy of the polyp showed non-specific inflammation with no evidence of malignancy. Follow-up maxillofacial CT revealed a large mass lesion in the right maxillary sinus, right nasal fossa, much of the ethmoids and right sphenoid, with destruction of adjacent bony structures...

We report clinical and pathological features of enzootic nasal adenocarcinoma (ENA) in one sheep in Algeria. A one-year-old Ouled Djellal sheep from a large herd (~1240 animals), located in Bordj Bou Arreridj, Algeria, was clinically diagnosed by the presence of persistent seromucous nasal discharge, head shaking, muzzle licking, dyspnoea, exophthalmia and frontal protrusion. The sheep was euthanized, and the necropsy was performed. Gross examination showed soft touch, pinkish-white tumour masses in the nasal cavities with distortion of the turbinates and of the medium septum...

Hemangiopericytomas (HPCs) are uncommon vascular tumors originating from extracapillary cells called pericytes, and rarely occur in the nose or paranasal sinuses. We treated a 57-year-old man with nasal HPC who presented with nasal obstruction and hemorrhage. Nasal endoscopy showed a readily bleeding mass between the right nasal septum and inferior turbinate. Enhanced CT revealed a heterogeneous mass lesion with an enhancement effect that filled the right nasal cavity. A biopsy specimen was proved to exhibit a HPC histopathology...
