Is it necessary to remove irregular melanocytic nevi

Whether irregular melanocytic nevi need to be removed depends on specific morphological characteristics and the doctor's evaluation. If there are blurred edges, uneven color, large diameter, recent changes, or accompanied by itching and bleeding, surgical resection is usually recommended. Stable nevi without obvious malignant features can be observed regularly. The necessity of removing irregular melanocytic nevi mainly depends on their potential risk of malignant transformation. The clinical evaluation criteria include ABCDE rule: asymmetry, irregular boundaries, color mottled, diameter exceeding 6 millimeters, and recent evolutionary features. It is recommended to clarify the nature of moles with two or more risk factors through pathological examination. Surgical methods such as fusiform resection and cosmetic suturing are often used to thoroughly remove the lesion and reduce scar formation. postoperative tissue biopsy is required to confirm the presence of melanoma cells. If malignancy is diagnosed, the resection range should be expanded and subsequent treatment should be coordinated. Some melanocytic nevi with smooth surfaces, clear edges, and long-term stability do not require excessive intervention, but require professional dermatoscopy monitoring every six months. Moles in special areas such as the sole of the foot and nail bed that are prone to friction, even if their morphology is regular, may increase the probability of malignant transformation due to chronic stimulation. Daily exposure to ultraviolet radiation and mechanical friction should be avoided, and the size and color changes of the mole should be recorded. If abnormal swelling or exudation is found, immediate medical attention should be sought. Regardless of whether surgical resection is chosen or not, it is recommended to undergo a professional skin examination annually, especially for high-risk individuals with a family history of melanoma or a history of sunburn. Physical sun protection is necessary for daily care, avoiding the use of corrosive dot mark products. If changes in the size or texture of the mole body or abnormalities in the surrounding skin are found, timely medical attention should be sought from a dermatologist. A personalized treatment plan should be developed after evaluation by professional instruments.
