[Obsessive-compulsive disorder in dermatology]

[Psychosomatic disorders of the scalp]

Psychosomatic disorders of the scalp have some special characteristics due to the visibility, possible stigmatization, and amount/patterns of hair. Of practical relevance is trichotillomania, which is now classified as an obsessive-compulsive disorder (OCD). Patients who are obsessed with normal physiological hair loss represent a further psychodermatological challenge. Psychosomatic therapy includes basic psychosomatic care, behavior therapy, or treatment with psychopharmaceuticals.

[Self injury in adolescence]

Self-injury often occurs for the first time in adolescence. The current classification distinguishes several groups: (1) factitious disorder imposed on self and factitious disorder imposed on another, (2) nonsuicidal self-injury (NSSI) and (3) obsessive-compulsive (OCD) and related disorders. The differential diagnosis includes a wide spectrum of psychiatric diseases, including borderline personality disorder (BPD), inherited disorders like Lesch-Nyhan syndrome (LNS) and also body modifications. In all these cases, self-harm is a subphenomenon. This review focuses on typical dermatological pictures.
