In nevi, it has been noted in about 2% of cases.2The Spitz nevus (spindle and epithelioid cell nevus or benign juvenile melanoma) is a benign tumor found predominantly in children and adolescents.3 In a recent review of TEE of nevus cells in the Archives, Kantor and Wheeland4 reported three cases of benign melanocytic tumors with TEE, one a Spitz nevus. Transepidermal elimination of nevus cells of a Spitz nevus was also present in one of the six cases reported by Yuki et al.2 Weedon and Little3 reported that 36% of 211 cases of Spitz nevi showed evidence of an upward migration of nevus cells within the epidermis.
