Before undergoing thyroidectomy, we performed molecular diagnostic tests that revealed the absence of BRAF(V600E) and the presence of RET/PTC-1 in one nodule and RET/PTC-3 in the two others.
When microdissected and sequenced separately, one nodule was positive for BRAF (v-raf murine sarcoma viral oncogene homolog B1) V600E and the other nodule was wild type at the BRAF codon 600.
