Ductal papillomas have unique papillary features arising from the salivary gland duct system. It comprises three rare benign adenomas, namely, inverted ductal papilloma, sialadenoma papilliferum and intraductal papilloma. Here the first case of intraductal papilloma developed in the minor salivary gland of the vestibule of the oral cavity in a 71-year-old Chinese female living in a nursing home...

Background. Oral squamous papillomas are benign pedunculated masses that grow most commonly on the palate. These benign lesions rarely cause symptoms. Methods. Here we present the case of a large, elongated squamous papilloma of the uvula causing dysphagia. We also review pertinent literature related to these lesions. Results. This patient underwent surgical excision of her atypically symptomat...

Cellular retinole acid-binding protein (cRABP) was detected in the cytosol of virus-induced papilloma (Shope) of rabbit skin. The Shope papilloma cRABP showed the same ligand specific ity and sedimentation value (2S) as was found in other animal species. The level of cRABP in the papillomatous tissue was significantly higher than that in the normal rabbit skin and increased in accordance with t...

BACKGROUND Inverted papilloma surgery is currently performed primarily with an endoscopic approach, a technique that has a recurrence rate of 12%. However, a recent study reported a recurrence rate of 5% with a strategy based on subperiosteal dissection of the tumor, with limited indications for using an external approach. The aim of this work was to evaluate whether different teams using the s...

BACKGROUND Oncologic outcomes for sinonasal and skull base squamous cell carcinoma (SCC) treated with an endoscopic endonasal approach (EEA) needs investigation. METHODS Patients with SCC treated with EEA were stratified by treatment strategy and tumor etiology and reviewed. RESULTS Thirty-four patients were treated with EEA, or which 27 had definitive resection and 7 had debulking surgery....

Inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. In the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. This article presents the results of a prospective study of 24 patients with inverted papilloma resected by th...

Laryngeal carcinoma and laryngeal papilloma are the most commonly encountered tumorous lesions in the larynx. Herein, we report a case of the mass arising from the left vocal cord in a 49-year-old Japanese man. Endoscopic examination suggested that the mass is a tumor such as carcinoma and papilloma. Pathological examination showed that the specimen demonstrated actinomycosis in the left vocal ...

The finding of virus particles by transmission electron microscopy (TEM) in fixed cervical and vaginal scrape material and their identification as papilloma viruses by negative staining is described. The colposcopic, cytological, and histological appearances in a group of 10 patients in whom virus particles were seen are discussed and the possibly considered of an association between papilloma ...
