NUTM1 and nut midline carcinoma: Previous studies have described the cytological features of 4 common NMCs harboring a BRD3/4-NUT fusion gene [9, 10] and another NMC case in which the gene rearrangement was not analyzed [11]; the cytological characteristics of these NMCs showed a highly cellular, predominantly noncohesive pattern of relatively small cells with a round nucleus, scant cytoplasm, irregular nuclear contours, variably prominent nucleoli, and identifiable mitotic figures.
