The nose and paranasal sinuses are contiguous with the lower respiratory tract. Patients with bronchiectasis and cystic fibrosis commonly have sinonasal disease, which is thought to have the same aetiology and pathophysiology as the chronic lung disease. Despite this, the conditions are rarely considered together and there is very little literature on the treatment of sinonasal disease in bronc...

BACKGROUND Intestinal-type sinonasal adenocarcinoma (ITAC) is an uncommon neoplasm, which resembles adenocarcinoma of the gastrointestinal tract. ITAC occurs sporadically or in association with occupational exposure to hardwood dust and other agents. AIMS To investigate the phenotype and possible pathogenetic mechanisms of primary sinonasal and nasopharyngeal adenocarcinomas by staining for c...

UNLABELLED Technical and technological innovations have spearheaded the expansion of the indications for the use of endoscopic endonasal approaches to extirpate malignancies of the sinonasal tract and adjacent skull base. OBJECTIVE Critical review of the available literature regarding the use of endoscopic endonasal approaches including indications, limitations, surgical techniques, oncologic...

ee front matter & 2005 dip.2005.10.009 719 2613; fax: +1 818 71 ess: lester.d.thompson@ Summary Malignant neoplasms of the sinonasal tract encompass a wide variety of epithelial, lymphoid and mesenchymal tumours. The separation and classification of epithelial or neuroepithelial tumours is sometimes challenging, especially when treatment and prognosis are different. Squamous cell carcinoma, ker...

Adenocarcinomas of the sinonasal tract may originate from respiratory surface epithelium or the underlying seromucinous glands. These malignancies are divided into salivary-type adenocarcinomas and non-salivary-type adenocarcinomas. The latter are further divided into intestinal-type and nonintestinal-type adenocarcinomas. This review provides an update on tumor classification, differential dia...
