RET fusions are the main molecular driver in the DSPTC. In this example, the tumor involved the entire gland (A) with associated Hashimoto’s Thyroiditis (B), numerous psammoma bodies (C), extensive lymphatic invasion (D), squamous differentiation (E) and showed a mixture of follicular (F) and solid (F) patterns.
