Objectives Sinonasal cancers with neuroendocrine features share similar clinical, radiological, and histopathological features; however, these tumors often exhibit varying degrees of aggressive behavior presenting significant treatment challenges. The objective of this study was to report our experience with these rare malignancies and to present a review of current literature. Methods Following institutional review board approval, the records of all patients with biopsy-proven sinonasal malignancies over a 5-year period were reviewed...

BACKGROUND: Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy of unknown etiology with a poor overall prognosis. Its relative rarity has made it difficult to determine the impact of different treatment modalities on survival. METHODS: Retrospective study of cases in the National Cancer Data Base (NCDB). NCDB cases that were diagnosed as having SNUC between January 1, 2004, and December 31, 2013 were included in the analysis. Outcomes of patients treated with surgery followed adjuvant chemoradiotherapy were compared with definitive chemoradiotherapy...

Poorly differentiated sinonasal malignancies are amongst the hardest differential diagnoses in pathology, owing to the large number of rare entities that arise there. Complicating the matter is that most pathologists, including those with experience in head and neck pathology, have little experience in any one of these rare entities. Most patients with sinonasal carcinoma present with locally advanced disease and in the past a combination of chemotherapy, radiotherapy, and surgery would usually be recommended without the specific disease subtype playing a large part of the decision making...

CONCLUSION: The sensitivity and specificity of a (18)FDG-PET scan may be different according to the histology. The SUVmax and SUV ratio may reflect the tumor's aggressive behavior. OBJECTIVES: To describe the characteristics of PET/CT scans, including the maximum standard uptake values (SUVmax), at initial diagnosis according to six main types of sinonasal malignancies: sinonasal adenocarcinoma (SNAC), sinonasal undifferentiated carcinoma (SNUC), adenoid cystic carcinoma (ACC), sinonasal malignant melanoma (SMM), olfactory neuroblastoma (ONB), and sinonasal neuroendocrine carcinoma (SNEC)...

Sinonasal tract malignancies are uncommon, representing no more than 5% of all head and neck neoplasms. However, in contrast to other head and neck sites, a significant proportion of sinonasal neoplasms tend to display a poorly/ undifferentiated significantly overlapping morphology and a highly aggressive clinical course, despite being of diverse histogenetic and molecular pathogenesis. The wide spectrum of poorly differentiated sinonasal epithelial neoplasms with small "basaloid" blue cell morphology includes basaloid squamous cell carcinoma (both HPV+ and HPV-unrelated), nasopharyngeal-type lymphoepithelial carcinoma (EBV+), small/large cell neuroendocrine carcinoma, esthesioneuroblastoma, poorly differentiated carcinoma of salivary type (myoepithelial carcinoma and solid adenoid cystic carcinoma), NUT midline carcinoma, the recently described SMARCB1-deficient sinonasal carcinoma, sinonasal teratocarcinosarcoma and, as a diagnosis of exclusion, sinonasal undifferentiated carcinoma (SNUC)...

High-grade neuroendocrine carcinomas (HGNECs) of the head and neck have the morphological appearance of undifferentiated carcinomas and could be histologically similar to human papillomavirus (HPV)-associated non-keratinizing squamous cell carcinomas of the head and neck. The aim of the study is to characterize histologically, immunohistochemically, and virologically these unusual neoplasms. Nineteen HGNECs of the head and neck (1 oropharyngeal, 5 sinonasal, 7 of the larynx, and 6 of the parotid gland) were reviewed and analyzed with a immunohistochemical panel, with special emphasis on cell cycle proteins...

SMARCB1 (INI1)-deficient sinonasal carcinomas were first described in 2014, and this series of 17 cases represents the first imaging description. This tumor is part of a larger group of SMARCB1-deficient neoplasms, characterized by aggressive behavior and a rhabdoid cytopathologic appearance, that affect multiple anatomic sites. Clinical and imaging features overlap considerably with other aggressive sinonasal malignancies such as sinonasal undifferentiated carcinoma, which represents a common initial pathologic diagnosis in this entity...

Over the past decade surgery for sinonasal malignancies encroaching into the anterior skull base (ASB) has evolved from open craniofacial resection to the use of minimally invasive transnasal endoscopic approaches. Using these techniques, ASB reconstruction is most often performed in a multilayer fashion with autologous free grafts (fascia lata or iliotibial tract) which leads to the production of abundant nasal crusting in the postoperative months and discomfort for patients. In carefully selected cases, we propose harvesting a flap from the contralateral nasal septum based on the septal branches of the anterior and posterior ethmoidal arteries (Septal Flip Flap, SFF), which can be rotated to resurface the ASB defect...

INTRODUCTION: Sinonasal undifferentiated carcinoma (SNUC) is an exceedingly rare and aggressive tumor that carries a poor prognosis due to its non-specific presentation and advanced stage at time of diagnosis. Early detection and treatment are vital, with chemotherapy, radiation, and surgery all being viable options. The literature is sparse and there is no consensus for optimal treatment. In surgical candidates, the otolaryngologist must have a vast skill set in order to resect the tumor with wide margins and reconstruct the defect in hopes of returning the patient to their pre-morbid state...

Sinonasal undifferentiated carcinoma (SNUC) represents less than 1% of all malignancies. Most of the tumors are diagnosed at an advanced stage, when they have already invaded neighboring tissue structures. We describe the cases of 2 patients with a substantial intracerebral extension of SNUC who were treated at our institution. One was treated with surgery followed by chemoradiotherapy. The other was primarily treated with induction chemotherapy with a combination of docetaxel, cisplatin, and 5-fluorouracil followed by concurrent chemo- and radiotherapy...

OBJECTIVE: Risk of nodal involvement in patients with sinonasal small-cell carcinoma and sinonasal undifferentiated carcinoma (SNUC) has not been well defined because of their rarity. We describe a population-based assessment of specific nodal level involvement in this group of rare neuroectodermal tumours. METHODS: The Surveillance, Epidemiology and End Results (SEER) database from 2004 to 2011 identified patients with SNUC and sinonasal small-cell carcinoma. Overall neck involvement and individual nodal level involvement at presentation were assessed, and comparison was made with a contemporaneous cohort of patients with a borderline clinically significant risk of nodal involvement and recurrence...

NUT midline carcinoma (NMC) is a fatal cancer that arises in various tissues along the upper midline of the body. The defining molecular feature of NMC is a chromosomal translocation that joins (in the majority of cases) the nuclear testis gene NUT (NUTM1) to the bromodomain protein family member 4 (BRD4) and thereby creating a fusion oncogene that disrupts cellular differentiation and drives the disease. In this study, we report the case of an adolescent NMC patient presenting with severe facial pain, proptosis and visual impairment due to a mass arising from the ethmoid sinus that invaded the right orbit and frontal lobe...

It is now well established that human papillomavirus (HPV) is an important causative factor in a subgroup of head and neck cancer. In the head and neck, while HPV is strongly associated with squamous cell carcinoma arising in the oropharynx, there is a growing interest in HPV-associated neoplasms of non-oropharyngeal origin including those which arise within sinonasal and nasopharyngeal mucosa. This article reviews current literature on the association of HPV with Scheiderian papillomas, sinonasal squamous cell carcinoma, sinonasal undifferentiated carcinoma, carcinoma with adenoid cystic-like features, and nasopharyngeal carcinoma...

Various hematolymphoid lesions involve the sinonasal tract, including aggressive B, T, and NK-cell neoplasms; myeloid sarcoma; low-grade lymphomas; indolent T-lymphoblastic proliferations; and Rosai-Dorfman disease. Differentiating aggressive lymphomas from non-hematopoietic neoplasms such as poorly differentiated squamous cell carcinoma, olfactory neuroblastoma, or sinonasal undifferentiated carcinoma may pose diagnostic challenges. In addition, the necrosis, vascular damage, and inflammatory infiltrates that are associated with some hematolymphoid disorders can result in misdiagnosis as infectious, autoimmune, or inflammatory conditions...
