Nevus spilus with synchronous melanomas: case report and literature review.

BACKGROUND

Nevus spilus is a rare, acquired, and often large cutaneous lesion consisting of a light brown background macule containing varying numbers of small darker macular or papular areas.

OBJECTIVE

Nevus spilus may contain dysplastic melanocytic elements, and there are also reports of melanoma arising from nevus spilus. However, the absolute risk for malignant transformation is not well defined.

CONCLUSION

We discuss a case of synchronous melanomas arising from a nevus spilus and potential management recommendations based on a review of the pertinent literature.
