It is a metabolic disorder of the eyelids that is characterized by the deposition of lipid-like material in the skin tissue, mostly on the medial side of the upper eyelid but also on the lower eyelid. The lesions are progressively larger, usually the size of a grain of rice to a pea, and do not develop or fade on their own. The occurrence of lid warts is a result of the formation of lipid-containing tissue cells within the skin, sometimes with increased lipids, lipoproteinemia, atherosclerosis, etc. It is an outward cutaneous manifestation of a systemic disorder of lipid metabolism. However, it has been verified by example that more patients with lid warts have no obvious positive signs or laboratory findings of the above mentioned diseases. Sweat duct tumors are adenomas of the small sweat ducts in the epidermis. Some patients have a family history of these tumors, which are twice as common in women as in men. The lesions are skin-colored, yellowish or brownish flat papules, 1 to 3 mm in diameter, firm and clustered but not fused, and generally without conscious symptoms. The etiology of the disease is unclear, and therefore there is no definitive conclusion on how to prevent it. The papules may gradually increase in size or size or fuse with each other, causing serious cosmetic disorders. Treatment: Once detected, early treatment is required. The current treatment is “tumor reduction” treatment, that is, the use of erbium laser or CO2 laser to remove the tumor above the skin surface, so as to improve the appearance, the skin is more flat, after treatment may still recur, depending on the speed of recurrence after several years can be treated again, there is no cure.
