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.
迈耶森痣出现在黑素细胞性损害周围出现罕见的局灶性、暂时性湿疹样发疹时。同样的现象在非黑素细胞性损害中也有观察到。在此，我们报告一例25岁男性患者，他在两个月前注意到腹部有两个痣周围出现瘙痒性红斑晕。皮肤镜检查发现这些损害不典型，随后对这两个痣进行了手术切除。组织病理学检查显示发育异常的复合性黑素细胞痣，周围有表皮内水疱和海绵形成。本报告提示迈耶森现象似乎不会改变痣的皮肤镜特征。
