Anatomic location, presence of single or multiple lesions, and knowledge of distribution of adnexal structures should be considered in development of a differential diagnosis.Appendageal tumors often serve as markers of underlying genetic syndromes.Risk of malignant degeneration varies with individual lesions, and is more common with sweat gland tumors than pilosebeceous tumors.
