Abstract: Low-grade nasopharyngeal papillary adenocarcinoma is an extremely rare tumor, with only a limited number of cases reported in the literature. Some published studies have paid more attention to the clinicopathological features of nasopharyngeal adenocarcinoma, while little effort has been made to study the optimal therapeutic strategies. We report about a woman diagnosed with low-grade nasopharyngeal papillary adenocarcinoma. She received the treatment approach that combined transnasal endoscopic surgery to remove the lesion with postoperative radiotherapy for nasal cavity. There was no evidence of recurrence after 4 months of surgery, and further follow-up is being continued. Through this example, we wanted to explore the optimal therapeutic strategies for primary nasopharyngeal adenocarcinomas.

Keywords: nasopharyngeal adenocarcinoma, immunohistochemistry, treatment policy, survival and prognosis
