Epidermolysis bullosa (EB) nevi are large, eruptive, asymmetrical, often irregularly pigmented melanocytic lesions. Such nevi may give rise to small satellite nevi surrounding the primary nevus, and thus frequently manifest clinical features suggestive of melanoma. They usually arise in sites of previous bullae or erosions. At least twice a year all persisting wounds and EB nevi should be evaluated with a low threshold for histopathologic examination if warranted. Our practice is to punch biopsy EB nevi showing dermoscopic features of concern as well as dermoscopically featureless lesions. Given the skin fragility and potentially impaired wound healing in EB patients, we avoid prophylactic total excision of large EB nevi, but rather use the dermoscope to select appropriate sites for punch biopsies within giant EB nevi.
