Grossly， it show black discoloration at skin surface. All for section after bisection.Sections show a picture of dysplastic compound nevus with limited nests of nevus at basal epidermis and dermis. Lentiginous epidermal hyperplasisa and confluent of basal melanocytes is noted. The nevus cells in the dermis shows relative progressive maturation. There is no evidence of melanocytic pagetoid transepithelial spreading. The surgical margins are clear.第二個excision ---Small dysplastic junctional nevusThe specimen consists of a piece of greyish， elliptical skin， measuring 0.6 x 0.4 x 0.3 cm in size. A grey brown pigmented lesion is present at its central portion. All for section.The section shows skin tissue with small nests of nevus cells in the base epidermis with confluent of melanocytes but extense tissue artifact showing separation of basal epidermis. Large amount melanin pigment deposition with pigment transepithelial permeation is noted. There is no evidence of malignancy in the specimen examined. The surgical margin is free. Suggest clinically follow up.醫師是說還沒惡化成惡性，說持續觀察3. 這算變異的痣嗎?? 不除掉 之後一定會變成癌嗎??4.請問這些不良痣變成癌的機率大嗎??5.有甚麼檢查方式可以檢查身上的痣呢?還是只能用手術??身上小痣也有幾十棵 陰囊部位容易病變嗎??6.眼白也有小顆的斑點，也有機會病變嗎??(長好幾年了)
