Concomitant BRAF(V600E) mutation and RET/PTC rearrangement is a frequent occurrence in papillary thyroid carcinoma..     ///    The aim of this study was to determine the prevalence of concomitant BRAF(V600E) mutation and RET/PTC rearrangements in the same tumor and its association with some clinicopathological features.     ///    The present study demonstrates that concomitant BRAF mutation and RET/PTC rearrangement is a frequent event in PTC..     ///    "Concomitant subclonal BRAF and RET/PTC were demonstrated in 14 PTCs (19.4%), and none of the oncogenes was detected in 22 tumors (30.5%). "    ///    RET/PTC was present in 26 tumors (36.1%).
