title: [Two superficially spreading malignant melanomas on nevus spilus].
abstract: A case of a 49-year-old patient with two superficial spreading melanomas arising from a naevus spilus is presented. Although opinions differ on the potential for malignant transformation in naevi spili, they should be carefully watched, and if changes are found these lesions should be subjected to histopathologic examination.
