Sweat duct adenoma is a benign exocrine sweat duct adenoma. 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 rather than solitary, with the best sites being the eyelids and face, axillae, periumbilical region, upper chest, and female genitalia. The lesions have specific histological features: numerous comma-shaped ducts in the dermis, such as “tadpoles”. The lesions can be aesthetically disfiguring and most patients wish to have them removed. The most advanced treatment for sweat duct tumors is the ultra-pulsed fractional co2 laser, which can be used for one to two treatments, and most patients heal after 7 days of debridement without recurrence. A small number of patients have an erythematous reaction that disappears in about 1 month.
