Nevus spilus is clinically defined as a pigmented skin lesion composed
of a light brown macule on which darker, circumscribed macular or pap
ular lesions appear at a later stage, Histologically, nevus cells have
been found both in pigmented spots and in the background stain. Cases
of transformation into melanoma have been reported in the literature
and the excision of these lesions is therefore justified. We discuss s
urgical techniques used in seven patients with nevus spilus and define
their indications with respect to the characteristics of the lesion.
