Most of them are mainly moles on the face, mostly for two reasons: one is for aesthetic reasons, mostly seen in young women, and the other is for superstitious reasons, thinking that moles under the eyes are bad and affect the luck, such as “tear moles For example, the mole under the eye is said to be a “tear mole”, which is mostly found in primary and secondary school students. Personally, I think that most of the moles we talk about are benign tumors that do not cause harm to the human body, and if you do not care much about the appearance and facial preference. We do not recommend “spotting” moles, because “spotting” moles may give improper stimulation to stable mole cells and make them proliferate actively, and even if they are removed, they may grow again and even induce malignant changes. There is also the possibility of infection if the mole is not properly taken care of after the spotting. I have seen a male patient in his 50s who originally had a mole on the back of his nose, but due to his frequent picking and scratching, the surface of the mole broke down and grew into basal cell carcinoma. Although this is only an isolated case, it is enough to show that moles should not be moved casually, especially those junctional moles and mixed moles. A nevus is also called a pigmented nevus or melanocytic nevus. From the medical point of view, nevus is a nest or mass formed by nevus cells proliferating in the skin, and because nevus cells can secrete melanin particles, the surface is black or brown, hence the name nevus or pigmented nevus. Most people have more or less nevi on their bodies, and they can be found on any part of the body, but most of them are found on the face, neck, back and upper limbs, some of them appear at birth, while others appear about a year after birth. With age, nevus cells gradually extend from the epidermis to the dermis and their number increases, reaching a peak at puberty. According to the different deposition sites of nevus cells in the skin, nevus can be divided into three types, namely intradermal nevus, junctional nevus and mixed nevus. Most of the hemispherical nevi seen in plain are intradermal nevi, which are generally stable in nature and not easy to be malignant. Moles with cells distributed between the epidermis and the dermis are junctional moles, and most of them are flattened, and moles with both of these characteristics are mixed moles. So should we “point” or not to “point” the moles on our body? If there is no special need and if the mole has no obvious tendency to become malignant, we do not advocate “spotting” moles. Mole “spotting” should be done in good physical condition, without systemic diseases or skin infections. At present, “mole spotting” mainly adopts surgical and non-surgical treatments (laser, freezing, ionization). For small and shallow moles with no signs of malignancy, non-surgical treatments can be used; for larger moles or moles suspected of malignancy, surgical excision followed by suturing is recommended. In addition, there are also folk medicines to remove moles, but most of these medicines are corrosive, and if they are not mastered well, they can easily injure normal skin or corrode too much, causing local infection, leaving deeper scars, and even inducing malignant changes due to serious improper stimulation. Many people worry about leaving scars after “spotting” moles, but whether a mole will leave scars after “spotting” varies from person to person, and depends on the characteristics of the mole (such as size, depth, and nature) and the method taken. Finally, we will talk about the signs of malignant change of melanoma. The original stable moles rapidly increase in size and color within a short period of time, and there are self-conscious symptoms such as itching and pain, irregular shape of moles, burr-like edges, loss of mole hairs, easy to break down and bleed, and ulcers.
