Abstract
Although melanocytic nevi have a relatively uneventful course throughout their existence, some may develop an inflammatory reaction known as the Meyerson phenomenon. Initially, the Meyerson phenomenon has been exclusively described in melanocytic nevi. However, it has since been observed in both pigmented and non-pigmented lesions, thus expanding the description from Meyerson nevus to the phenomenon. We report a case of an unusual Meyerson phenomenon arising from a congenital melanocytic nevus characterized by a weeping eczematous response.
