TERT and nevus: When we compared the patients with melanomas positive for the TERT staining in over 50% of the cells and the patients with melanomas that stained in under 50% according to clinicopathological variables, a significant difference was observed between the two groups regarding age (p = 0.031), the personal history of melanoma (p = 0.012), and melanomas developed on a preexistent nevus (p = 0.032) (Table 3).
