黑痣

一、什麼是黑痣?

答:大部份的人在臉上、頸部、手臂…等幾乎全身上下或多或少會有一些深淺不一的痣。大部份的 痣呈現黑色,若長在臉部等較為明顯處,常會造成美觀甚或命相學上的不良反應

二、為什麼會形成黑痣?

答:黑痣,主要是因皮膚內痣細胞良性增生,而產生黑色素而造成的。分為先天性與後天性兩種。

先天性的黑痣將來有衍生為皮膚癌的危險,尤其是當其顏色與面積變化,或是有突發性的出血、潰 爛或搔癢時更應立即求診。而後天性黑痣的形成一定是由平面而後變大凸起,倘若一開始即為凸 起,也應注意可能會衍生為皮膚癌。

三、黑痣有分哪幾種症狀?

答:依其生長於皮膚組織層面之不同,而分為:

接合型

形狀較為平坦的斑塊,顏色由淺至深棕色均有,分佈於皮膚表皮層與真皮層接合處 真皮痣

痣細胞聚集於真皮層內,又稱皮內痣,顏色較淡,外形多凸起圓頂狀或疣狀。

複合痣

略為凸起,除了分佈位置除了皮膚表皮層與真皮層接合處之外,還深入至真皮層,為接合痣與真皮 痣的混合型。

四、有什麼方式可以治療黑痣?

答:除痣的方法有分為化學性與物理性兩種。化學點痣最好是找專業的皮膚科醫師,多以三氯次酸 來除較淺的痣。而物理性除痣法,則以雷射點痣居多,利用色素性雷射儀,如:紅寶石雷射,將黑 色素去除。
