BACKGROUND: The level of p53 protein expression in sinonasal squamous cell carcinoma (SNSCC) has been estimated, but the results remain inconsistent and the point of consensus has not been reached. This study was first determined to evaluate the clinical effects of p53 expression in SCC of the sinonasal tract. METHODS: According to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement criteria, the potential literature was searched from diverse databases...

Sinonasal (Schneiderian) papillomas are benign neoplasms that arise in the sinonasal tract. Since their initial descriptions, sinonasal papillomas have triggered debate regarding their classification, etiology, rate or predictors of malignant transformation, and other issues. While significant strides have been made in recent years, there are still aspects of sinonasal papillomas that remain unclear even now. This review will serve to update the practicing pathologist on the current understanding of sinonasal papillomas...

OBJECTIVE: We previously reported a modified endoscopic medial maxillectomy (modified transnasal endoscopic medial maxillectomy through prelacrimal duct approach [MTEMMPDA]) to resect inverted papilloma (IP), for which the inferior turbinate (IT) and nasolacrimal duct (ND) can be preserved. MTEMMPDA is a safe and effective method to obtain wide, straight access to the maxillary sinus (MS). However, there are few reported cases of patients who underwent MTEMMPDA, and even fewer of patients who underwent partial osteotomy of the apertura piriformis and the anterior wall of the MS...

BACKGROUND: Human papilloma virus (HPV) infection has been shown to play an integral role in the development and prognosis of various head and neck cancers. Generational changes in sexual behavior may have led to an increased incidence of positivity in recent years. HPV positivity in both benign and malignant lesions of the sinonasal cavities has been shown in previous studies (estimates range from 20%-30% for malignancy). We intend to investigate if HPV positivity affected survival outcomes in our patient cohort...

Inverted papilloma is a rare, benign sinonasal tumor. Its etiology is the most likely related to HPV infection. Inverted papilloma originates from the ciliated respiratory epithelium, typically from the lateral nasal wall. The tumor is characterized by endophytic growth inwards the stroma with adjacent tissues destruction. The clinical symptoms are non-specific, such as: unilateral obstruction of the nasal duct, rhinorrhoea, epistaxis and anosmia. The treatment consists in a complete surgical excision of the tumor...

BACKGROUND AND PURPOSE: Because sinonasal inverted papilloma can harbor squamous cell carcinoma, differentiating these tumors is relevant. The objectives of this study were to determine whether MR imaging-based texture analysis can accurately classify cases of noncoexistent squamous cell carcinoma and inverted papilloma and to compare this classification performance with neuroradiologists' review. MATERIALS AND METHODS: Adult patients who had inverted papilloma or squamous cell carcinoma resected were eligible (coexistent inverted papilloma and squamous cell carcinoma were excluded)...

BACKGROUND: Squamous cell carcinoma (SCC) of the sinonasal cavity is a rare entity that arises as either de-novo tumors or from inverted papillomas (IPs). In this study we evaluate and compare oncologic outcomes of sinonasal SCCs based on their etiology and treatment strategy. METHODS: This investigation was a single-center, retrospective review comparing de-novo SCCs (n = 28) and those associated with IPs (n = 38) resected during the period from 2000 to 2015. Demographic and tumor data, surgical approach, recurrence, and clinical outcomes were analyzed...

A significant fraction of nasopharyngeal and sinonasal tumors are associated with Epstein-Barr virus (EBV) or human papillomavirus (HPV). Nasopharyngeal carcinoma (NPC) and extranodal NK/T-cell lymphoma harbor EBV in practically all cases, although a small proportion of cases of the former harbor HPV. Sinonasal inverted papillomas harbor HPV in about 25% of cases. Sinonasal squamous cell carcinomas harbor transcriptionally active HPV in about 20% of cases, and limited data suggest that this subset has a better prognosis than the HPV-negative subset...

Inverted Papilloma (IP) is an uncommon and locally aggressive benign tumour of sinonasal region, which tends to recur after surgical resection. Most tumours are confined to the lateral nasal wall and sinuses, with maxillary sinus being most commonly affected and a male preponderance. It has a known association with in situ and invasive carcinomas with a <10% rate of malignant transformation. Most common association has been seen with squamous cell carcinoma and extremely rare association with adenocarcinoma and small cell carcinoma...

PURPOSE OF REVIEW: The inferior turbinates are routinely examined by otolaryngologists on anterior rhinoscopy and nasal endoscopy. Most lesions of the inferior turbinate are benign but can often be confused with malignancy. This review highlights the broad differential of nonmalignant lesions of the inferior turbinates and their management. RECENT FINDINGS: A variety of infectious, inflammatory, neoplastic, and vascular lesions may affect the inferior turbinates...

BACKGROUND: Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases...

INTRODUCTION: F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) is useful for the staging and assessment of treatment response in patients with lymphoma. Occasionally, benign lesions demonstrate avid FDG uptake and result in false positive findings. CASE: We report the case of an 82-year-old man presenting with cutaneous lesions, which were histopathologically diagnosed as intravascular lymphoma. FDG-PET/CT for staging demonstrated an FDG-avid mass extending from the right maxillary sinus to the nasal cavity, moderate uptake in the adrenal glands, mild uptake in the knee and the foot, and faint uptake in the skin and subcutaneous tissue of the legs...

BACKGROUND: Precise localization and excision of the originating site of a sinonasal inverted papilloma (SNIP) is essential for decreasing tumor recurrence. In this study we evaluated the use of preoperative computed tomography (CT) and magnetic resonance imaging (MRI) to pinpoint the attachment/originating sites of SNIPs in 143 patients. METHODS: Osteitis signs in CTs and convoluted cerebriform pattern (CCP)-based reverse tracings from MRIs of 143 SNIP patients were analyzed preoperatively to predict the originating site of SNIPs...
