GABBI, Tatiana Villas Boas et al. Clinical, dermoscopic and histopathological evaluation of the Meyerson nevus: case report. An. Bras. Dermatol. [online]. 2010, vol.85, n.5, pp.681-683. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962010000500012.
Meyerson nevi occur whenever a rare focal and transitory eczematous eruption arises around melanocytic lesions. The same phenomenon has also been observed in non-melanocytic lesions as well. Herein we report the case of a 25 year old, male patient, who had noticed, two months before, the arising of a pruriginous and erithematous halo around two nevi localized on his abdomen. The lesions were found to be atypical on dermoscopic examination and he was submitted to surgical excision of both nevi. Histopathological examination revealed displastic compound melanocytic nevi, surrounded by intraepidermical vesicles and spongiosis. Present report suggests that Meyerson phenomenon does not seem to alter dermoscopic features of nevi.
