Small meatballs on the top of the neck may be filiform warts and molluscum contagiosum, which can be treated with retinoic acid cream and imiquimod cream according to the cause of the disease, but the efficacy of topical medications is limited, and laser, freezing, and surgical treatments can be performed if necessary. Filiform warts are usually susceptible to human papilloma virus infection when the immune system is low and the skin is broken; molluscum contagiosum, also known as dermatofibrosum, may be associated with viral infection, skin aging, and other factors, and is a benign tumor of the skin that is commonly found in the elderly and sweaty population. Both diseases can be treated with retinoic acid cream and imiquimod cream, but topical medications are not as effective or have side effects that may damage the skin. Liquid nitrogen freezing and laser treatments are usually available, and surgical treatments are used to remove bumps for larger flesh grains. If you have a small flesh grain on the top of your neck, it is recommended that you go to the hospital in time, and after clarifying the cause of the disease, follow the doctor’s instructions to use reasonable treatment.
