Atypical melanocytic lesions in epidermolysis bullosa.
We report a 6-year-old female with recessive dystrophic epidermolysis bullosa (RDEB) who presented with a very large acquired melanocytic lesion. The lesion demonstrated many features both clinically and histologically that made the distinction from malignant melanoma difficult. The pathogenesis of this lesion and other unusual melanocytic lesions seen in the setting of acute and chronic blistering disorders seems related to repeated episodes of disruption of the dermal-epidermal junction.
