BACKGROUND: The mechanism underlying the malignant transformation of inverted papilloma (IP) has not yet been elucidated. METHODS: To clarify the genes responsible for the malignant transformation, we analyzed 10 cases of IP, 8 of IP with dysplasia, and 11 of squamous cell carcinoma (SCC) by targeted amplicon sequencing. RESULTS: The number of mutant genes increased in the order of IP < dysplasia < SCC. Significant differences were observed in the mutation rates of three genes (KRAS, APC and STK11) in particular...

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...

Olfactory neuroblastoma/esthesioneuroblastoma (ONB) is an uncommon neuroectodermal neoplasm thought to arise from the olfactory epithelium. Little is known about its molecular pathogenesis. For this study, a retrospective cohort of n = 66 tumor samples with the institutional diagnosis of ONB was analyzed by immunohistochemistry, genome-wide DNA methylation profiling, copy number analysis, and in a subset, next-generation panel sequencing of 560 tumor-associated genes. DNA methylation profiles were compared to those of relevant differential diagnoses of ONB...

OBJECTIVES/HYPOTHESIS: Tenuous evidence has supported the hypothesis that sinonasal inverted papilloma (SNIP) arise from human papillomavirus (HPV) infection. To clarify the role of HPV in SNIP, all known HPV sub-types were evaluated by employing a robust polymerase chain reaction-based method in a wide variety of SNIPs from a single institution. STUDY DESIGN: Retrospective surgical specimen tumor sample analysis. METHODS: HPV positivity among SNIP samples and those with squamous cell carcinoma (SCC) were compared...

BACKGROUND: Sinonasal inverted (schneiderian) papilloma (IP) is histologically benign but shows a propensity for malignant transformation. Survivin, a member of the inhibitor of the apoptosis family of proteins that controls cell division, apoptosis, metastasis, and, probably, also neoangiogenesis, is overexpressed in essentially all human cancers. Overexpression of the multidomain protein cortactin has also been associated with increased cell migration, invasion, and metastatic potential in several malignancies...

BACKGROUND AND OBJECTIVES: We have previously indicated that EGFR has a role in carcinogenesis in a subgroup of sinonasal squamous cell carcinomas (SNSCC). In addition, EGFR activates 2 of the most important intracellular signalling pathways: PI3K/pAKT/mTOR/pS6 and MAP pathway kinases. The objective of this study was to evaluate the involvement of the EGFR/PI3K/pAKT/mTOR/pS6 pathway and its relationship with clinical-pathological parameters and follow-up of sinonasal squamous cell carcinoma...

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...

PURPOSE OF REVIEW: Review the recent literature regarding the management of orbital invasion in sinonasal malignant tumors. RECENT FINDINGS: There is a recent trend in preserving the orbit in cases of minimal invasion of periosteum and limited periorbit involvement, as well as in presence of good response to neoadjuvant chemotherapy, mainly in squamous cell carcinoma and neuroendocrine histologies. SUMMARY: The decision about orbital exenteration in cases of sinonasal malignancies is facilitated if the patient already has clear clinical signs of intraconal invasion such as visual loss, restriction of ocular mobility or infiltration of the eyeglobe...

Introduction: Inverted papilloma is a locally-aggressive benign neoplasm of the paranasal sinuses with a high potential for recurrence and malignancy. Intracranial extension is infrequent, and dural penetration even more so, typically associated with recurrence of the disease or its degeneration into squamous cell carcinoma. Clinical Case: A 32-year-old female patient consulted us for an exophytic lesion in her right nostril and exophthalmos, associated with headache, anosmia and dysgeusia...

Primitive tumors of pterygopalatine fossa (PPF) are often benign tumors or extension of a malignant sinonasal tract. Primitive tumors may rarely occur in PPF.The authors present a 71-year-old woman with a 6-month history of left cranial nerve palsy. Magnetic resonance imaging and positron emission tomography-computed tomography showed an enhancing isolated lesion at the PPF. A transmaxillary biopsy was performed, leading to diagnosis of primitive squamous cell carcinoma. The patient underwent radiotherapy treatment...

Neuroendocrine neoplasms (NENs) are infrequent in sensory organs. There are well-differentiated neuroendocrine neoplasms that should be classified as neuroendocrine tumors, in analogy to their gastrointestinal counterparts, however the nomenclature is inconsistent. The best defined entities are neuroendocrine tumors in the middle ear and ectopic pituitary adenoma in the sphenoid region. Poorly differentiated NENs most often arise in the olfactory organ and nasal cavity that are represented by olfactory neuroblastomas and poorly differentiated neuroendocrine carcinomas...

BACKGROUND: Sinonasal cancer carries a poor prognosis, especially in recurrent stages, and it is a disease with very limited treatment options. METHODS: The expression of programmed death ligand-1 (PD-L1) as a marker for immunotherapy was evaluated in 53 sinonasal squamous cell carcinoma (SCC) and 126 intestinal-type adenocarcinoma (ITAC) samples. Results were correlated to clinicopathological characteristics and follow-up data. RESULTS: Membranous PD-L1 staining of tumor cells was observed in 34% (18/53) of the sinonasal SCC samples and in 17% (22/126) of the ITAC samples...

Malignancies of the nasal cavity and paranasal sinuses account for 1% of all malignancies and 3% of malignancies of the upper aerodigestive tract. In the sinonasal tract, nearly half of all malignancies arise in the nasal cavity, whereas most of the remaining malignancies arise in the maxillary or ethmoid sinus. Squamous cell carcinoma is the most common histological subtype of malignant tumors occurring in this area, followed by other epithelial carcinomas, lymphomas, and malignant soft tissue tumors. Although many of these tumors present with nonspecific symptoms, each tumor exhibits characteristic imaging features...

BACKGROUND: The use of endoscopic resection as an alternative to open surgery for sinonasal malignancies has increased in the past 20 years. METHODS: The National Cancer Database was queried for cases of sinonasal squamous cell carcinoma (SNSCC) without cervical or distant metastases that were treated surgically between 2010 and 2014. They were split into 2 groups based on surgical approach: open or endoscopic. Demographics, facility and insurance type, stage, tumor characteristics, postoperative treatment, 30-day readmission rate, 30- and 90-day mortality, and overall survival (OS) were compared between the 2 groups...

Background: Inverted sinonasal (Schneiderian) papilloma (ISP) is a locally aggressive neoplasm often associated with sinonasal squamous cell carcinoma (SNSCC). While the etiology of ISP is not well understood, human papillomavirus (HPV) has been detected in a subset of cases. Our group recently identified activating somatic EGFR mutations in the majority of ISP and ISP-associated SNSCC. However, the relationship between EGFR mutations and HPV infection has not been explored. Patients and methods: We evaluated 58 ISP and 22 ISP-associated SNSCC (including 13 patients with matched ISP/SNSCC samples), as well as 14 SNSCC without clinical or pathologic evidence of an associated ISP...
