Sweat duct tumors primarily appear as flat papules close to the skin color and are most often found around the eyelids. Sweat duct tumors are adenomas of the ducts of the small sweat glands within the epidermis that are more likely to develop in women and tend to worsen during puberty. Sweat duct tumors present as single or multiple small, flat papules about a few millimeters in size, and may have a normal skin color, yellowish or brownish appearance. The lesions are benign, although the papules may gradually increase in size and become aesthetically displeasing. Some patients have a family history prior to the onset of the disease. Treatment methods mainly include liquid nitrogen freezing, carbon dioxide laser and electrocautery, etc. The appropriate treatment method should be chosen under the guidance of the doctor.
