Rare Sinonasal Non-intestinal Type Adenocarcinoma of Right Nasal Septum

Abstract

Sinonasal tract is a complex anatomic structure with many possible diagnoses. Common diagnoses that usually encountered from the biopsied samples are inflammatory polyps and papillomas as well as squamous cell carcinoma. Another entity which most poorly understood is low grade glandular or tubular proliferations which includes reactive lesions, respiratory epithelial adenomatoid hamartoma, seromucinous hamartoma, and low grade sinonasal adenocarcinoma. We describe a case of a young male with right nasal septum mass which found incidentally upon flexible nasopharyngolaryngoscopic examination, who was referred earlier for possible obstructive sleep apnea. After excision of the tumour was done, it was confirmed to be low grade sinonasal adenocarcinoma non-intestinal type. This case highlights the rarity of the entitiy of low grade sinonasal adenocarcinoma nonintestinal type involving the right nasal septum; and how its subtle finding can be mistaken to be a clinically benign condition.
