NUT carcinoma is a rare and highly aggressive malignancy, predominantly affecting adolescents and young adults. This tumor demonstrates rapid progression, resistance to conventional anti-cancer treatments, and an extremely poor prognosis. Currently, research on NUT carcinoma is limited, and effective treatment options remain scarce. In this study, we performed single-cell RNA sequencing (scRNA-seq) on tumor tissue from a 13-year-old patient with maxillary sinus NUT carcinoma. The analysis revealed significant heterogeneity among epithelial cells within the tumor microenvironment (TME). Immune cell infiltration was notably low, suggesting that the tumor represents a "cold" immune microenvironment. Subclustering of epithelial cells identified distinct subpopulations characterized by high proliferation, metabolic activity, TGF-Beta-driven invasiveness, and MYC-driven growth and protein secretion. These findings provide critical insights into the tumor's biology, growth mechanisms, and potential therapeutic vulnerabilities. This study highlights the importance of scRNA-seq in understanding the complexity of NUT carcinoma and underscores the need for personalized treatment approaches, including the potential application of BET inhibitors.
