A Case of the Low-Grade, Non-Intestinal type Sinonasal Adenocarcinoma of Nasal Septum

ABSTRACT

Adenocarcinomas of the sinonasal tract are relatively rare. Such tumors are divided into salivary and nonsalivary types as classified by the World Health Organization. Nonsalivary sinonasal adenocarcinomas are further classified as intestinal (ITAC) and non-intestinal (non-ITAC), which can be separated even further into high-grade and low-grade. Low grade non-ITACs are more uncommon than ITACs. In this study, we present a case of low-grade non-ITAC in a 61-year-old woman who was successfully treated with wide excision without radiotherapy, and we also provide a review of the literature.
