In the benign lesions TERT mRNA positive tumours were associated with the presence of lymphocytic infiltrate (p < 0.0001), 85% of the FTAs (11 cases) with positive TERT mRNA expression had lymphocytic infiltrate vs. 15% (2 cases) negative for the presence of lymphocytic infiltrate (Table 4). The gene discussed is TERT; the disease is neoplasm.
