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.
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.
