討論 1971年,Meyerson[1]報道2例患者,出現痣相關的紅斑、脫屑及瘙癢,外用糖皮質激素治療后好轉,受累痣周圍遺留輕度色素減退,數月后消失。該病種后命名為Meyerson痣,表現為中心痣病損及其周圍濕疹化,又稱暈濕疹或暈皮炎。此后,該現象引起人們注意,相繼報道了伴有周圍環狀濕疹樣改變的多種色素性皮損,包括交界痣、非典型痣及先天性痣,甚至還報道了非色素細胞皮損,如基底細胞癌、脂溢性角化等,這種現象稱為Meyerson現象[2]。Meyerson痣是良性的,通??稍跀翟聝茸匀幌耍瑹o需治療。如存在瘙癢,可使用糖皮質激素外用及抗組胺藥物口服。濕疹暈消退后,中心痣通常繼續存在,反之,中心痣切除后,通??墒節裾钕薣3]。
