Is surgical treatment of sebaceous nevus good?

Sebaceous nevus is relatively common, especially in infancy and childhood. If these symptoms are not relieved, the damage will thicken and expand during adolescence. Its treatment includes non-surgical treatment and surgical treatment. Surgical treatment can completely remove it and the effect is more reliable.

1. Sebaceous nevus is relatively common, usually occurring at birth or shortly after birth, and is prone to occur on the head and neck, especially on the scalp. Most are single shots, and a few are multiple shots. The rash is characterized by well-defined, raised, round nodules that are pale yellow to gray-brown in color and have a waxy appearance. No hair grows on the surface of the scalp lesions. During puberty, the lesions thicken and enlarge, becoming papilloma-like in surface and distinctly yellow in color. In adults, sebaceous nevi become warty and firm in texture.

2. The changes in tissue structure with age can be roughly divided into three periods. In infancy or childhood, in addition to mild hyperplasia of the epidermis, small, incompletely differentiated hair follicle structures can be seen, while the sebaceous glands are underdeveloped. During adolescence, the epidermis shows warty or papilloma-like hyperplasia, and a large number of mature or nearly mature sebaceous glands are seen in the dermis. Fully developed apocrine sweat glands can be seen deep in the dermis or in the subcutaneous fat beneath the sebaceous lobules. There is a tendency for adnexal tumors to develop in the later stages of skin lesions, with basal cell carcinoma occurring in approximately 10% to 15% of cases.

3. To prevent the occurrence of tumors, surgical removal can be performed completely, or electrocautery, laser and other treatments can be used.

4. Non-surgical treatment includes cryosurgery, electrocautery, electrodessication, and CO2 laser.

5. Surgical treatment: The surgical resection must be deep enough to reach the apocrine glands to ensure reliable results. Curettage can also be performed.
