Tumor cells from randomly chosen AM cases were also micro-dissected from the FFPE sections and subjected to DNA sequencing to confirm the immunohistochemical results.<h4>Results</h4><i>BRAF</i> V600E mutation was detected in 71.8% of the AM samples, while 65.5% of samples with UAs demonstrated <i>BRAF</i> V600E positivity. The gene discussed is BRAF; the disease is neoplasm.
