Abstract
|
|
|
|
Adenocarcinoma is the third most common mucosal malignancy found in sinonasal tract, after squamous cell carcinoma and adenoid cystic carcinoma, and represents approximately 15% of all sinonasal cancers. The 2005 World Health Organization (WHO) classification of sinonasal adenocarcinoma (SNAC) includes 2 categories : salivary- and nonsalivary-type SNACs. Nonsalivary types are classified into intestinal type SNAC (ITAC) and non-intestinal type SNAC (non-ITAC), each of which is separated into low- and high-grade categories. Low-grade non-ITAC can arise in the sinonasal tract ; the nasal cavity is the mostly afftected, followed by the ethmoid and maxillary sinuses. Over recent years, little doubt remains that low-grade non-ITAC represents a separate entity based on morphology, ultrastructural features, and behavior. There was no report about low-grade non-ITAC arising from nasal septum in South Korea. We performed successful endoscopic excision of this rare case, and so present it with literature review.
