The WHO classifies carcinomas originating in the paranasal sinuses, nasal cavity, and the skull base based on their histological appearance and genetic alterations into different groups—squamous cell carcinomas, lymphoepithelial carcinoma, HR HPV-related carcinomas (multiphase and monophase), NUT rearranged carcinomas, undifferentiated carcinomas (SNUC), neuroendocrine carcinomas, adenocarcinomas, and SWI/SNF complex-deficient carcinomas [16,17]. Here, NUTM1 is linked to nasopharyngeal type undifferentiated carcinoma.
