OBJECTIVE To determine whether or not patient race and ethnicity affect sinonasal cancer survival. STUDY DESIGN Retrospective database analysis. SETTING National Cancer Institute's Surveillance, Epidemiology, and End Results Database, 1988-2010. SUBJECTS AND METHODS Sinonasal carcinoma cases were extracted according to site codes and histology recode-broad groupings. The cohort was used t...

Introduction and Objectives: Sinonasal tumours represent only 3% of all head and neck cancers. Adenocarcinoma is the second most frequent histopathology type. Hardwood exposure has been considered a risk factor. Sinonasal adenocarcinoma grows silently which leads to a late diagnosis and low survival rates. The aim of this study was to present our experience in the management of the patients wit...

INTRODUCTION AND OBJECTIVES The high variability of sinonasal anatomy requires the best knowledge of its three-dimensional (3D) conformation to perform surgery more safely and efficiently. The aim of the study was to validate the utility of Osirix® and stereolithography in improving endoscopic sinonasal surgery planning. METHODS Osirix® was used as a viewer and Digital Imaging and Communicati...

Solitary extramedullary plasmacytomas (EMPs) are nonepithelial neoplasms of plasma cell origin categorized among non-Hodgkin lymphomas, without the bone marrow involvement and systemic spread seen in multiple myeloma. They are uncommon tumors comprising 3% of all plasma cell neoplasias. Although they usually occur in the upper respiratory tract, only 1 case of EMP localized to the frontal sinus...

Low-grade adenocarcinomas that primarily arise within the sinonasal tract are uncommon tumors. We report here on three cases of primary sinonasal low-grade adenocarcinomas. The patients were 2 females and 1 male with ages of 48, 57 and 64, respectively. Microscopically, the tumors had a well developed tubulopapillary growth pattern that consisted of columnar or pseudostratified cells with eosin...
