In the study conducted by Cho et al. on acral melanoma, TERT protein expression by immunohistochemistry was present in more than half of acral lentiginous melanomas and nonacral cutaneous melanoma, in 40% of the nonlentiginous acral melanomas, in all metastatic acral lentiginous melanomas and no acral nevi. This evidence concerns the gene TERT and acral lentiginous melanoma.
