Carcinomas of the upper aerodigestive tract with rearrangement of the nuclear protein of the testis (NUT) gene (NUT midline carcinomas).

This manuscript reviews carcinomas of the upper aerodigestive tract associated with genetic rearrangements of the nuclear protein of the testis (NUT) gene, also known as NUT midline carcinomas. The literature is reviewed regarding all reported cases of NUT midline carcinomas and the clinicopathologic features are discussed. Our current understanding of the molecular pathogenesis of the disease is also discussed, along with the differential diagnosis for undifferentiated or poorly differentiated malignancy of the upper aerodigestive tract.
