I. Re-awareness of pigmented nevus.
Pigmented nevus, with no gender difference in onset, has the largest number at the age of 21-30, and starts to fade on its own at the age of 70-90, is a benign lesion and does not need any treatment; if it affects aesthetics, it can be surgically removed and sent for pathological examination after surgery to check whether there is malignant change.
What kind of pigmented nevi need timely treatment?
1. Suddenly fast growth, rapid expansion and irregular shape.
2. Deepening and brightening of color, uneven distribution of pigment, pigment loss, local redness and inflammation.
3. The surface changes from smooth to rough.
4. Hairy nevus starts to lose hair.
5. There is oozing or bleeding and ulceration at the nevus.
6. There are enlarged lymph nodes nearby.
7. Small hard lumps are formed in the nevus or there are satellite nevi around it.
8. Itching and tingling in the nevus without feeling.
9. The surface elevation of the mole disappears.
What kind of moles need preventive excision?
1.Moles that grow on the palm and finger area and the area that is easy to rub.
2.Moles that have been treated with medicine, freezing, laser, etc. and then recur.
3.Halo moles (moles with white halo around them).
Why is laser freezing treatment not recommended for pigmented moles?
Most pigmented nevi accumulate in the dermis, and treatment must break through the dermal papillae layer, so open trauma processes such as laser and freezing can easily form scarring with poor results.
2. In laser and freezing treatment, the color of pigmented nevus will become lighter and lighter as the nest of nevus cells is destroyed, but when the color is not visible to the naked eye, it does not mean that the nest of nevus cells disappears, therefore, laser and freezing treatment is often incomplete and pigmented nevus is prone to recurrence.
3. If repeated laser freezing treatment is given to recurrent moles, and the nest of nevus cells is not completely removed, such stimulation will greatly increase the chance of pigmented nevus malignant transformation.
Why should surgery be preferred to remove pigmented moles?
1.Surgery can cut out pigmented moles.
2.Fine cosmetic suture is good for wound healing to reduce scar formation.
3.The cut specimen can be sent to pathological examination to prevent misdiagnosis and leakage, and those with malignant tendency should be further treated or observed for follow-up.
VI. What are the precautions before mole removal?
1. It is not recommended to remove moles with scar body.
2.Do not put on makeup before surgery and clean the skin carefully.
3.If you need to cut moles surgically, stop using anticoagulant drugs (aspirin, etc.) three days before surgery.
4. Patients with diabetes, abnormal coagulation function, hyperthyroidism, etc. should undergo surgery under the guidance of physicians.
VII. What are the precautions after surgery?
1. The treated area should not be exposed to water for about a week.
2, according to the different conditions of each patient, different times of follow-up, please follow the doctor’s instructions for timely follow-up treatment to ensure the efficacy.
3.For those who have scabs, please let the scabs fall off by themselves, do not tear off by yourself.
4.Avoid sunlight exposure as much as possible to reduce the occurrence of hyperpigmentation.
5.Do not eat too spicy and stimulating food within one week.
6.Do not receive treatment such as exfoliation or microdermabrasion during the treatment period.
7.One week after surgery, you can use normal daily skin care products.
8.There is a pigmentation period after surgery, and pigmentation needs a slow biological process to subside, so you need to come to the hospital for regular follow-up.
