BACKGROUND: Recurrence of inverted papilloma (IP) is a problem in 12-17% of tumors. Controversy exists regarding benefits of intraoperative frozen section histopathology (IFSH) for IP resection; however, to our knowledge, no study has specifically investigated this. IFSH for IP resection is the standard of care in our practice. We, therefore, reviewed our outcomes of using IFSH for IP resection. A secondary goal was to assess the reliability of IFSH. METHODS: Patients with IP who underwent surgical resection (2010-2016) with minimum 9-month follow-up were included...

Sinonasal inverted papilloma is a relatively rare disease; however, it is prevalent enough for every ENT practitioner to encounter it several times throughout medical routines. Despite the developments in experimental and clinical medicine as well as surgical techniques, our knowledge of this disease is still inadequate. With improved imaging and better diagnostic techniques, proper diagnosis and qualification for surgical approaches leave no doubt. Although the endoscopic approach seems to be the gold standard for such condition, some cases may additionally require an external approach...

Objective: Sinonasal inverted papilloma (IP) is a benign and uncommon tumor of the nasal cavity and paranasal sinuses with a tendency for recurrence and even malignant transformation. Though the morphology and clinical behavior of this lesion has been well described, its etiology remains controversial. Methods: Computerized searches were performed in PubMed, Scopus, and Google scholar through May 2015. In this review, etiologic factors including human papilloma virus (HPV), Epstein-Barr virus (EBV), cell cycle related proteins and angiogenic factors, occupational and environmental exposures, and chronic inflammation, will be discussed...

AIMS: Mutations in FGFR3 and the promoter region of the telomerase reverse transcriptase (TERT) gene have been frequently found in urothelial carcinoma of the urinary bladder. However, related data for papillary urothelial neoplasm of low malignant potential (PUNLMP) are limited. In this study, we investigated the mutation status of the TERT promoter, FGFR3 gene, and HRAS gene in low-grade papillary urothelial neoplasms and evaluated their prognostic significance. METHODS AND RESULTS: The cases included in this study comprised 21 inverted papillomas, 30 PUNLMPs, and 34 low-grade noninvasive papillary urothelial carcinomas (NIPUCs)...

Ductal papillomas are rare benign papillary tumours of the minor salivary glands. Previously they have been classified into three subtypes: inverted ductal papilloma (IDP), sialadenoma papilliferum and intraductal papilloma. The oral inverted ductal papilloma is the least common of these lesions, with 48 cases reported to date in a search of the English-language literature. We describe an interesting case of oral IDP and highlight the pertinent clinical and histopathological features. Importantly, unlike the histologically similar inverted papilloma (IP) of the nose and paranasal sinuses, oral IDP is a completely benign lesion and is not associated with malignant change...

BACKGROUND: Unilateral sinus disease (USD) occurs in 23 % of all cases. It is believed that it is mainly associated with cancer development. Retrospective data from large rhinological centers show that the most common USD is chronic rhinosinusitis (CRS), followed by mycosis, inverted papilloma and finally cancer, but only in a small percent of cases. THE AIM OF THE STUDY: The analysis of USD in the group of patients who underwent FESS at the secondary referral center...

Background: Inverted sinonasal 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...

An inverted schneiderian papilloma (ISP) is a rare neoplasm that affects the nasal cavity or a paranasal sinus, especially the maxillary sinus. Although histologically benign, the lesion has a high potential for local destruction, has a high recurrence rate, and presents the possibility of malignant transformation into squamous cell carcinoma. To determine the extent of the injury and possible impairment of adjacent maxillofacial structures, accurate imaging, such as cone beam computed tomography (CBCT), is necessary...

The olfactory cleft is the specific site of development of many tumours (respiratory epithelial adenomatoid hamartoma, intestinal-type adenocarcinoma, neuroblastoma, inverted papilloma, glomangiopericytoma, etc.) and is also the site of CSF rhinorrhoea via the cribriform plate (cribri-rhinorrhoea). Olfactory cleft surgery must therefore be considered to be a specific type of surgery, complementary to ethmoidal labyrinth surgery and anterior skull base surgery. Olfactory cleft tumours can be resected according to five different surgical procedures: olfactory cleft mucosal resection, partial resection of the olfactory cleft, total resection of the olfactory cleft, unilateral endoscopic anterior skull base resection, and bilateral endoscopic anterior skull base resection...

INTRODUCTION: Inverted papillomas (IP) are benign sinonasal neoplasms, which account for 0.5-4% of all nasal tumors. IPs have been known to transform into squamous cell carcinoma in 5-15% of cases. Rarely, transformations to other malignancies have been reported. Here we report a unique case of malignant transformation of an IP into sinonasal undifferentiated carcinoma (SNUC). METHODS: A case report with a literature review; institutional review board exempted. The clinical presentation, radiographic features, surgical intervention, histopathologic analysis, treatment, and outcome of the case were examined...

Nasal and sinonasal inverted papilloma (NSIP) is a benign tumor in which surface epithelial cells grow downward into the underlying supportive tissue with varying degrees of metaplasia. Human papillomavirus (HPV) has been proposed as the causal agent in the pathogenesis of this disease. Many studies have shown that HPV can activate the Akt/mechanistic target of rapamycin (mTOR) signaling pathway, but the role of this pathway in HPV-associated NSIP is largely unknown. In this study, we enrolled 40 control tissue samples and 80 NSIP tissue samples...

Elements are vital in airway mucosal physiology and pathology; but their distribution and levels in the mucosa remain unclear. The present study uses the state-of-the-art nuclear microscopy facility to map and quantify multiple elements in the histology sections of nasal mucosa from patients with nasal polyps or inverted papilloma. Our results demonstrate that P and Ca are the most abundant elements in mucosa and their distinct difference between epithelial and sub-epithelial regions; more importantly, our results reveal decreased amounts of Cu and Zn in the remodelled epithelium as compared to the normal epithelium...

Inverted papilloma of the nasal cavity is a benign neoplasm, although it can be locally invasive and has the potential for malignant degeneration. Inverted papilloma of the temporal bone is extremely rare. We describe a case of a 44-year-old woman who was treated for nasal inverted papilloma and was later found to have inverted papilloma of her temporal bone. The patient required several procedures to remove the inverted papilloma from the nasal cavity and temporal bone, and she is currently free of recurrence...
