Primary pulmonary NUT carcinoma: pathological features, clinical diagnosis, treatment, and prognosis - An extended review.

NUT carcinoma is a rare and aggressive lung tumor driven by NUTM1 gene rearrangements. It accounts for less than 1% of all lung cancers, with fewer than 100 cases reported worldwide. The disease is often misdiagnosed due to non-specific symptoms and histological overlap with other tumors. This review provides an updated overview of its pathological features, clinical presentation, diagnosis, treatment, and prognosis, aiming to serve as a practical reference for clinicians and pathologists.
