Abstract

Several dermatoses have been reported in association with Becker's nevus. Eczematous dermatitis associated with Becker's nevus is extremely rare, described in only two previous case reports. We report a case of 21-year-old male with recurrent eczema lesions which were always localized within the underlying Becker's nevus lesion. This case may be explained as a Wolf's isotopic response-like phenomenon.
