title: Hyperkeratosis of the nipple and areola.
abstract: Hyperkeratosis of the nipple and areola is a rare condition. We report two cases of hyperkeratosis of the nipple and areola occurring in men with no underlying endocrinopathy or synthetic estrogenic drug therapy. Both patients demonstrated prompt resolution of the hyperkeratosis of the nipples with a keratolytic gel. Because our cases were not associated with ichthyosis or epidermal nevus, they best fit into the category of nevoid hyperkeratosis of the nipples.
