FIRST PARAGRAPH: Adenocarcinomas of the sinonasal tract can originate in the respiratory epithelium or the underlying mucoserous glands. Most (60%) arise from the mucoserous glands. These tumors are divided into two categories: salivary-gland-type and nonsalivary-gland-type adenocarcinomas (table). The latter are subdivided into two major categories: intestinal-type adenocarcinomas (ITACs) and nonintestinal-type adenocarcinomas.
