- Classic follicular dyskeratosis: symmetrically arranged nodular lesions on the scalp, face, behind the ears, betweenvanes in the sternum and large folds
- isolated form: in addition to the typical knots from the back of the feet and hands appear warty kind of multifaceted papules that form plaques at the confluence
- Vezikullezno bullous form: in addition to papules formed bubbles filled with clear content.Such foci appear on the sides of the neck and in the large folds.On the soles and palms may develop a point keratosis (the appearance of keratinous areas)

In most cases diagnosed solely on clinical grounds, but in case of doubts about the established diagnosis is performed histological examination of affected skin

- Reception keratolytic drugs
- In order to reduce the risk of side effects and increase the effectiveness of treatment of vitamin A, is assigned to receive hepatic and vitamins
