Itchy white lumps around the anus may be related to chronic eczema, vulvar leukoplakia, sclerosing atrophic moss and other causes. 1. Chronic eczema: chronic eczema around the anus may appear hypopigmentation, resulting in lighter skin color, and may be self-conscious about itching of perianal skin. 2. Vulvar leukoplakia: white patches appear on the surrounding skin, which can spread to the perineum and perianal area, resulting in white patches in the perianal area, which can be accompanied by itching. 3. Sclerosing atrophic moss: If the papules grow in the perianal area, white patches may appear in the perianal area after the papules shrink, which may be accompanied by itching. It is recommended that those who have itchy white lumps around the anus, go to the hospital in time, clarify the cause of the disease, standardized treatment under the guidance of the doctor, and actively control the development of the disease to avoid aggravation of the impact of physical health.
