In the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors.

BACKGROUND High-resolution microendoscopy (HRME) enables real-time imaging of epithelial tissue. The utility of this novel imaging modality for inverted papilloma has not been previously described. This study examines the ability of otolaryngologists to differentiate between images of inverted papilloma and normal sinonasal mucosa obtained with a HRME. METHODS Inverted papilloma and normal si...

BACKGROUND Inverted papilloma involving the temporal bone is an extremely rare occurrence. Reports in the literature suggest a higher recurrence rate and association with squamous cell carcinoma in Schneiderian-type papillomas of the middle ear than in sinonasal Schneiderian-type papillomas. OBJECTIVES To investigate the expression of apoptosis-related proteins, markers of cell proliferation ...

PURPOSE To discuss the treatment and outcomes of inverted papilloma of the nasal cavity and paranasal sinuses. METHODS Review of the pertinent literature. RESULTS Inverted papilloma is a benign, locally aggressive neoplasm that arises in the nasal cavity and is associated with squamous cell carcinoma in approximately 5% of patients. Squamous cell carcinoma may be present with inverted papil...

INTRODUCTION The aim of this work was to analyze the occurrence of inverted papilloma within the nose and paranasal sinuses, the extent of lesions and the clinical course in the patients who underwent endoscopic surgery. MATERIALS AND METHODS Between the years of 2006-2012, at the Department of Otolaryngology and Laryngological Oncology, 2295 patients were subjected to surgery due to paranasa...

Sinonasal-inverted papilloma is a benign tumour with a high rate of recurrence, but possible malignant transformation. Therefore, investigation of predisposition to malignant transformation of sinonasal-inverted papilloma gives clinicians the opportunity for adequate treatment. Topoisomerase II-alpha (topoII-alpha) and Ki67 are markers of cell proliferation in both normal and neoplastic tissues...

Case Description- In this clinical report, occurrence of a rare case of canine cutaneous inverted papilloma was discussed. A 4-year-old, intact, male German shepherd dog was presented with multiple skin lesions, located on the inguinal region near the root of penis, which have been progressively growing since two months ago. In close examination of the lesions multiple, firm, painful, and cup-s...

The nasal cavity, paranasal sinuses, and nasopharynx are sites for a wide variety of tumors and non neoplastic conditions. Inverted papilloma accounts for about 0.5-4% of total nose and paranasal sinus tumours. Men are affected 4 times more often than women. The major types are fungiform papilloma, inverted papilloma, and oncocytic Schneiderian papilloma. The latter has often been referred to a...

Sinonasal inverted papilloma is a benign neoplasm of epithelial origin, which represents 0.5 to 4% of all sinonasal tumors. Despite the histological benign nature of this type of tumor, it has a high rate of recurrence after surgical resection and significant malignant potential. Sinonasal inverted papilloma is treated as a locally aggressive tumor. The aggressive surgical approaches, such as e...
