Sweat duct tumor is a kind of appendage tumor, the skin lesions occur in the eyelids, especially the lower eyelids and forehead skin, the lesions are small particles of light brown papules, slightly higher than the skin surface. Sweat duct tumors are scientifically defined as adenomas that form in the ducts of the epidermal sweat glands, and studies have shown that they are benign tumors of the sweat glands, usually inherited as chromosomally dominant genes.
