Epidermolysis bullosa nevus: case report and literature review.

[epidermolysis bullosa simplex]

Acquired melanocytic lesions resembling malignant melanoma have been described in all major categories of Epidermolysis bullosa and referred to as "Epidermolysis bullosa nevi ''. They easily induce to diagnostic error , although no malignant transformation has been reported . We report the development of a large acquired melanocytic nevus at a site of recurrent blisters in a 5 -year -old child with Epidermolysis bullosa simplex . The global dermoscopic pattern was suggestive of benignity , and the histopathological findings were compatible with a compound melanocytic nevus . This is the first published case of Epidermolysis bullosa nevi in Brazilian literature . Despite their benign behavior , we emphasize the importance of regular clinical and dermoscopic monitoring , since a malignant course still can not be totally excluded .
