Axl receptor tyrosine kinase is involved in the tumorigenesis and metastasis of many cancers. Axl expression was markedly higher in human papilloma virus type 16E6 (HPV16E6)-overexpressing HeLa (HE6F) cells and lower in HPV16E6-suppressing CaSki (CE6R) cells than in the controls. SiRNA-mediated knockdown of E6 expression led to increased phosphatase and tensin homolog (PTEN) phosphorylation at Ser380 and attenuated AKT phosphorylation. Expression of membrane-associated guanylate kinase inverted-2 (MAGI-2), an E6-induced degradation target, was induced in E6-siRNA-transfected cells...

Inverted schneiderian papillomas are rare benign tumors, most often arising from the sinonasal mucosa. We describe a case of a 59-year-old female with an inverted papilloma of the supraglottis. This is the first reported case of a supraglottic-presenting inverted papilloma. Although rare, this case demonstrates that these tumors should be considered during workup of supraglottic laryngeal masses. Laryngoscope, 2017.

Inverted papilloma (IP) is a benign tumor occurring in the nasal cavity and paranasal sinuses. It is reported that 5-15% of IPs undergo malignant transformation into squamous cell carcinoma (SCC), and the role of microRNAs (miRNA/miR) in this process remains to be elucidated. In the present study, whole miRNA profiles using samples of IP and SCC were investigated, in order to detect the function of miRNA in the carcinogenesis of IP. Samples from IPs (n=5) and SCC lesions (n=5), which arose from IPs, were used for miRNA analysis...

Over the past 10 to 20 years, endoscopic endonasal surgery has become for many teams the preferred treatment for sinonasal tumors. Technical advances in the field of surgical instrumentation (good visualization, hemostasis…) and the progress of imaging guidance (to avoid neurovascular complication) has made those procedures simpler and safer. Nevertheless, endonasal endoscopic procedures require a trained surgical team of ENT specialist and neurosurgeon. Endoscopic endonasal surgery has been reported to be feasible for all types of sinonasal tumors whether benign tumors such as inverted papillomas, or malignant tumors...

The nasal cavity and paranasal sinuses are covered with ciliated respiratory mucosa of ectodermal origin, known as Schneiderian epithelium, which can give rise to different types of sinonasal carcinomas. A 42-year-old woman with a history of nasal polypectomy 3 years previously presented with nasal obstruction and rhinorrhea. She was found to have a papillary mass involving the left nasal cavity, and the left maxillary and ethmoidal sinuses by radiologic examination. She underwent endonasal resection under the diagnosis of oncocytic papilloma...

Functional endoscopic sinus surgery (FESS) has considerably evolved over the past 20 years while minimally-invasive surgery also applies to sinus procedures. Development of new technologies combined with better knowledge of risks has allowed surgeons to achieve improved results in their FESS indications. One of the most difficult areas to visualize using the exclusive endoscopic approach is still the anterior recess of the maxillary sinus. Hence, external approaches, such as the Caldwell-Luc procedure, are still used by many surgeons to ensure visual control of this area in diseases such as fungal balls, mucoceles, inverted papilloma and other tumors...

Papillomas are uncommon tumors of the sinonasal tract histologically derived from the Schneiderian membrane. Three distinctive variants are described, the exophytic, the inverting and the oncocytic types. On physical examination, their appearance varies from exophytic-fungiform seen in the exophytic variant, to polypoid-papillary in both the inverting and oncocytic variant. The presence of an asymptomatic mass or epistaxis and unilateral nasal obstruction are the typical presenting symptoms. Clinically they tend to recur and, although benign, they may erode the bone laminas by pressure, especially the inverting type, causing proptosis and other co-morbidities...

Sinonasal inverted papilloma (SIP) is a benign tumor of the nasal cavity and sinus. SIP is characterized by aggressive malignant transformation and a high rate of recurrence. Inadequate removal of the tumor during surgery is one of the most significant contributors to SIP recurrence. A growing body of evidence suggests that molecular alteration in SIP, including human papilloma virus infections, single nucleotide polymorphisms of key genes, deregulation of signaling pathways and immunological changes, may lead to SIP occurrence and malignant transformation...

BACKGROUND: Inverted papilloma (IP) is the most common benign sinonasal neoplasm. Endoscopic techniques, improved understanding of pathophysiology, and novel surgical approaches have allowed rhinologists to treat IPs more effectively, with surgery being the mainstay of therapy. Frontal sinus IP poses a challenge for surgical therapy due to complex anatomy and potentially difficult surgical access. OBJECTIVES: We reported a unique case of a massive frontal sinus IP that presented with intracranial and orbital extension, with near resolution after chemotherapy...

OBJECTIVE: Sinonasal inverted papilloma has been traditionally managed with external surgical approaches. Advances in imaging guidance systems, surgical instrumentation, and intraoperative multi-visualization have led to a gradual shift from external approaches to endoscopic surgery. However, for anatomical and technical reasons, endoscopic surgery of sinonasal inverted papilloma extending to the frontal sinuses is still challenging. Here, we present our experience in endoscopic surgical management of sinonasal inverted papilloma extending to one or both frontal sinuses...

INTRODUCTION: Sinonasal Inverted Papilloma (IP) constitute relevant therapeutic problem due to destructive character of growth, tendency to recur and the possibility of malignant transformation. Therefore, many attempts to identify risk factors for IP occurrence have been undertaken, as well as research to find markers that would allow for the earlier detection of tumors and the application of adequate therapy. A widely known risk factor of IP is HPV infection. One of the markers of HPV infection and the ongoing effect of this change (although arousing some controversy) is the expression of the p16 protein...
