At histopathological diagnosis, the malignant lesions described among TIP at radiolabeled PSMA ligands PET corresponded to papillary thyroid carcinoma in most of the cases and less frequently to follicular thyroid carcinoma, Hürthle cell carcinoma, and metastases to the thyroid gland [46,47,48,49,50,51,52]. This evidence concerns the gene FOLH1 and thyroid gland papillary carcinoma.
