There is no clinical pore keratosis, but rather perifollicular keratosis, sweat keratosis or follicular keratosis. All three of these diseases are closely related to genetics and are in fact keratosis pilaris. For example, patients can apply topical ointments such as retinoic acid ointment, salicylic acid ointment, urea vitamin E ointment, and cod liver oil ointment. For patients with keratosis pilaris, fluorouracil can also be used as a sealant. For small areas of keratosis pilaris, medical aesthetic treatment can be applied. Of course, perifollicular keratosis and follicular keratosis do not generally lead to malignant conditions, but patients with sweat pore keratosis must be checked regularly in the clinic, because the condition may become malignant.
