Sweat duct tumor on forehead can be treated by electrocautery, laser treatment and surgery, but it is easier to recur. 1. Electrocautery: If the anhidrosis is located in the superficial part of the skin, which seriously affects the patient’s beauty, the tissue around the anhidrosis can be dried up by electrocautery, so as to achieve the therapeutic effect. 2. Laser treatment: if the anhidrosis only appears in local tissues and the number is relatively small, the thermal effect of laser can be used to make the local tissues necrotic, so as to achieve the therapeutic purpose. 3. Surgical treatment: the lesion can be removed directly through surgery, or skin grinding can be used to remove the lesion with electro-abrasion or microcrystalline grinding to eliminate the protruding skin lesion. Patients who need to treat anhidrosis should choose regular hospitals for consultation, and can take targeted treatment measures under the guidance of professional doctors.
