In contrast to all other reported cases of NUT carcinomas harboring a NUTM1::bromodomain complex gene fusion, our patient’s tumor showed histologic and immunophenotypic features of a specific, non-squamous carcinoma: (1) thyrocyte differentiation with prominent colloid production, (2) diffuse expression of PAX8 (monoclonal) and TTF1 with thyroglobulin reactivity in colloid, and (3) essentially absent (0 to < 2%) expression of p63, p40, and cytokeratins 5/6. Here, PAX8 is linked to squamous cell carcinoma.
