Rare Nasopharyngeal Neuroendocrine Tumor in a 26-Year-Old Female: Case Report and Literature Review.

Neuroendocrine neoplasms (NENs) represent a collection of highly varied tumors that originate from neuroendocrine cells. They are considered rare tumors that predominantly affect the lungs. Epithelial NENs can be categorized into neuroendocrine tumors (NETs) and neuroendocrine carcinomas. It is extremely rare for NET grade 1 (NET G1) to exist in the nasopharynx, these tumors are slow-growing and the onset of symptoms and identification of the tumor may take several years. The majority of cases occur in ages between 60 and 65 years. In this article, we present a case of a 26-year-old female who presented with recurrent epistaxis and nasal obstruction for one and a half years. Magnetic resonance imaging revealed a substantial nasopharyngeal mass. Subsequently, a biopsy was conducted, and the histopathological results indicated a NET G1. Our literature review revealed 5 cases of NET G1 in the nasopharynx, with our patient being the youngest among all published cases.
