As sweat duct adenomas are exocrine sweat duct adenomas. The pathology shows cystic dilatation of sweat ducts, with some damage in the form of small comma-like tails and adenomas of small sweat ducts located in the dermis. Therefore, it is critical to selectively remove the cystic dilated portion of the small sweat ducts. Once the extent and depth of damage is too great, scars can easily form on the eyelids, affecting the patient’s aesthetics and creating a psychological burden for the patient. The XL-RF skin treatment instrument is controlled with high precision, and when operated under a surgical microscope, it can selectively remove the lesion, avoiding damage to the normal surrounding tissues and obtaining scar-free results.
