What mole is the long mole on the left back side of the neck?

Everyone will have a mole, which is formed by the abnormal increase and accumulation of melanin particles secreted by melanocytes or melanocytes in the skin. For example, common moles are formed by the accumulation of increased melanocytes into nests or spheres; However, in Ota nevus and freckle nevus, there are many scattered melanocytes, which can present different colors due to different distribution depths. 2 What are the manifestations of moles? There are many kinds of nevus, the most common ones are localized nevus (divided into intersecting nevus, intradermal nevus and mixed mole according to the depth), in addition, there are giant nevus (with a huge area of congenital melanocyte nevus), halo nevus (skin around melanocyte nevus in hypopigmentation), simple freckles (nevus), freckles (appearing in exposed parts such as face, which darken and turn brown after sun exposure), brown and milk spots (with light brown spots at birth), and chloasma.
