Sweat duct tumors are benign exocrine sweat duct adenomas, 1-2 mm in size, firm papules of normal or yellow color, most commonly seen in females, with onset in adolescence; there is a familial tendency. The lesions are often multiple, with the best sites being the eyelids and face, the axillae, the umbilicus, the upper chest, and the female genital area. The lesions have specific histological features: many comma-shaped ducts in the dermis, such as “tadpoles”. The lesions are aesthetically disfiguring. The advantages of electrolysis treatment for sweat duct tumors are: minimal damage, good long-term results, no scarring; disadvantages: painful, multiple treatments to heal.
