Our results add to the evidence that, in contrast to follicular variants of oncoPTCs, predominantly follicular oncocytic thyroid tumors harbor neither RET/PTC rearrangements nor BRAF mutations.     ///    Molecular characterization of oncocytic thyroid malignancies for RET/PTC or BRAF genetic alterations may help with (preoperative) classification and prognostic evaluation of these tumors..     ///    "In oncocytic (H?rthle cell, oxyphilic) thyroid tumors, the presence of RET/PTC rearrangements is associated with either the conventional papillary histotype or the ""solid"" H?rthle cell tumors, whereas all predominantly follicular oncocytic carcinomas do not harbor RET/PTC chimeras.
