[Dermatologic indications for anti-androgenic treatment].

In spite of remarkable therapeutic results obtained by gestagens with antiandrogenic activity, usually combined with estrogen, in oily seborrhea, acne, Fox-Fordyce disease, androgenetic alopecia and hirsutism many dermatologist still hesitate to treat the named disorders by hormones. The reason for their hesitation appears to be the erroneous belief, that the named disturbances represent hormonal disorders the treatment of which does not belong to dermatology. After a survey on the mechanism of action of antiandrogens the basic difference between androgen dependent skin disorders and endocrinopathies with manifestation on the skin and its appendages is explained. Androgen dependent skin disorders, like oily seborrhea and most cases of acne are not the result of endocrine disturbances in the sense of an pathologically increased or decreased production of sexual hormons. Administering sexual hormons the physician takes advantage of the sebosuppressive effect of female sexual hormons as he does of the antiallergic activity of the hormon cortisol (and related compounds) in the treatment of eczemas. The antiandrogenic treatment of androgenetic alopecia, hirsutism and androgenetic acne--with their underlying hormonal disturbance, consisting in an increased production of androgens, represents an quasi etiological therapy. As in these cases the hormonal disturbances finds its expression mainly or exclusively in disorders of the skin or hair growth, the dermatologist, preferentially in cooperation with endocrinogists and/or gynacologists remains entitled to take over the treatment. The available drugs are discussed and suggestions are made for their appropriate use.
