Background Lobular capillary hemangioma is a rare benign tumor, most frequently located in the head or neck region, the nasal cavity being uncommonly affected. Its etiopathogenesis is not fully established, although traumatic and hormonal factors have been implied. Case Description A 50-year-old female patient underwent an uneventful endoscopic transsphenoidal removal of a pituitary cystic macroadenoma at our institution. Nasal packing was used in postoperative hemostasis. Histopathology was compatible with a gonadotrophin-producing adenoma...

Teratomas are benign tumours containing cells from ectodermal, mesodermal and endodermal layers with an incidence of about 1 in every 4,000 births. Their commonest site is sacro-coccygeal region, followed by anterior mediastinum. The incidence of teratomas localised to the head and neck region is around 2-9% of all cases. Epignathus is a rare congenital oropharyngeal teratoma originating from the base of the skull. Here we present a rare case of oropharyngeal teratoma in a neonate who was referred to our institute with an ill-defined oral mass protruding through a cleft in the hard palate...

Mucoceles are not often found in the maxillary sinus, and is a rare surgery complication, in this case, orthognathic. This review describes a mucocele that partially occupies the right maxillary sinus, causing a chronic nasal obstruction. This is the case of a 44 year-old female patient, which after 12 years of several orthognathic surgeries, presents facial pain and right nasal obstruction. The paranasal sinus computed tomography reveals a mass with liquid content that occupies the lower part of the right maxillary sinus and compromises the right nasal cavity...

Esthesioneuroblastoma is a rare malignant neoplasm of oflactory neuroepithelium and usually located at the olfactory cleft at superior nasal cavity. Ectopic localization of esthesioneuroblastoma is even rarer and usually posed with a diagnostic dilemma and delay in the diagnosis and management, We report a rare case of ectopic esthesioneuroblastoma of the sphenoclivus with the presentation of intermittent unilateral epistaxis, intermittent intractable headache without anosmia. Nasal endoscopy findings showed a pulsatile mass at the anterior face of the sphenoid sinus with extension posteriorly towards the clivus region and occupying the floor of the sphenoid sinus...

A 23-year-old male presented with a 3-month history of left purulent rhinorrhea, progressive nasal obstruction, and intermittent epistaxis. A fiberoptic examination revealed a large vascular polypoid mass completely filling the left nasal cavity. CT and MRI scans showed a large hypervascular mass involving the left nasal airway, maxillary antrum, and the anterior ethmoid cells. There was no bony erosion or contiguous spread, and the remaining sinuses, orbit, and cranial fossa were uninvolved. The patient underwent complete removal of the mass via an external lateral rhinotomy approach...

Heterotopic glial nodules of the scalp are non hereditary congenital malformations composed of mature brain tissue isolated from the cranial cavity. The majority of these lesions are found in the nasal region and occur rarely on the scalp. They are frequently diagnosed in newborn infants. However, they may rarely be found in adults. The pathogenesis of these lesions remains unknown. We describe the case of a temporal scalp nodule in a 50 year-old man. At the time of the excision, the mass was not associated with intracranial connection...

The term "sinonasal undifferentiated carcinoma (SNUC)" has been coined in 1986 for a highly aggressive sinonasal tract epithelial neoplasm showing distinctive morphology, but lacking any specific line of differentiation. Recent developments resulted in a dynamic splitting of new entities traditionally included in the spectrum of SNUC. Sinonasal NUT-midline carcinoma, adamantinoma-like Ewing family tumors and most recently, SMARCB1(INI1)-deficient sinonasal carcinoma are the main entities defined by specific genetic aberrations...

Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal tract that arises from olfactory epithelium. There have been reports, mainly in tumors treated with chemoradiation or with distant metastases, describing focal histologic changes of divergent cell populations within archetypal ONB. Only three cases have been reported of ONB coexisting with non-neuroendocrine tumors. We describe our experience with a 35-year-old male with a nasal cavity mass extending into the anterior cranial fossa...

PURPOSE: Hemangioma is a common benign vascular lesion of the head and neck region. It rarely involves the mucous membranes of the nasal cavity and paranasal sinuses. It should be added to the differential diagnosis of nasal cavity masses when the presenting symptoms are epistaxis or nasal obstruction. MATERIALS AND METHODS: A retrospective chart review was conducted of a histologic diagnosis of lobular capillary hemangioma or cavernous hemangioma of the sinonasal mucous membranes treated at the Chonbuk National University Hospital from January 1995 through December 2015...

Meningiomas are common intracranial neoplasms but extracranial meningioma of the paranasal sinus is extremely rare. The recommended treatment of these meningothelial tumors is complete surgical excision. The authors report a 79-year-old woman presenting with facial pain and nasal obstruction for several months. Endoscopic nasopharyngeal examination showed a right nasal mass that arose from the nasopharynx and reached around the middle meatus. Gadolinium-enhanced magnetic resonance imaging showed a well-circumscribed nasopharyngeal mass, which originates from the right rosenmuller fossa and extends to the right nasal cavity...

Maxillary incisor pseudo-odontomas are common in pet prairie dogs and can cause progressive respiratory obstruction, while mandibular pseudo-odontomas are rarely clinically significant. The aim of this retrospective cross-sectional study was to describe CT features of maxillary and mandibular incisor pseudo-odontomas vs. normal incisors in a group of pet prairie dogs. All pet prairie dogs with head CT scans acquired during the period of 2013-2015 were included. A veterinary radiologist who was aware of final diagnosis reviewed CT scans and recorded qualitative features of affected and normal incisors...

Solitary fibrous tumours are of mesenchymal origin and comprise of uncommon spindle cell neoplasias. Most commonly the lesions arise from pleura but other rarer sites include lungs, peritoneum, pericardium, nasal cavities, thyroid, parotid gland and orbit. We report the case of a 41-year-old male patient who presented to us with a painless, progressive growth of a mass in the superior part of left orbit with proptosis and inferotemporal displacement of the left eye. Computed Tomography (CT) scan revealed homogeneous enhancing lesion in the superior compartment of left orbit in the extraconal region, extending intraconally and distorting the globe...

Background Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. Patient and Methods/Case Report We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned...

Electrochemotherapy is a new modality of local cancer treatment that increases the delivery of chemotherapy drugs into tumor cells by applying intense electric fields. This novel electrochemotherapy application was applied as an adjuvant to surgery and eliminated intranasal tumors in dog. The treatment challenges are the surgery limitations due to anatomy and residual tumor in the bone cavity. Most of the tumoral mass on nasal cavity was surgically removed. The internal nasal cavity was immersed in liquid and bleomycin before applying electric field...

Neuroblastomas are sometimes associated with abnormal constitutional karyotypes, but the XYY karyotype has been rarely described in neuroblastomas. Here, we report a case of an esthesioneuroblastoma in a boy with a 47, XYY karyotype. A 6-year-old boy was admitted to our hospital because of nasal obstruction and palpable cervical lymph node, which he first noticed several days previously. A polypoid mass in the right nasal cavity was detected through sinuscopy. Biopsy of the right nasal polyp was performed. Based on the result, the patient was diagnosed with a high-grade esthesioneuroblastoma...
