For example, carcinomas comprise conventional squamous cell carcinomas, NUT carcinomas, DEK::AFF2 carcinomas, EBV- and HPV-associated carcinomas, undifferentiated as well as SWI/SNF complex deficient sinonasal carcinomas, highlighting the variety of different morphologies and molecular pathogeneses [1]. The gene discussed is AFF2; the disease is nut midline carcinoma.
