A 68-year-old woman developed three reddish nodules on a linear epidermal nevus on the right arm. The nodules and linear lesion were resected. The histology revealed the two larger nodules to be eccrine porocarcinoma and the other to be eccrine poroepithelioma. The linear lesion was actually epidermal nevus. To our knowledge, this is the first description of adnexal tumors developing on epidermal nevus.
