Psychogenic diseases of the skin

Psychogenic diseases of the skin - skin pathological changes observed in people suffering from disorders of the higher nervous activity.
Mental disorders often lead to violations of the vegetative nervous system of the patient and, therefore, to various vascular, secretory, trophic changes in the skin, resulting in the emergence of ischemia or stand hyperemia skin, loss and the graying of hair, exacerbation of pre-existing skin disorders (eczema, psoriasis and other). In hysteria, in particular, often see blisters, blisters, hemorrhage, necrosis on different areas of the skin that many authors tend to consider not as a result of self-harm, but as a manifestation of hemorrhagic diathesis in such patients.
Obsessive behavior among psychiatric patients often expressed in irresistible desire to injure yourself - dermatome. It is possible that a certain role in the emergence of dermatologii play paresthesias. Patients chew and swallow nails (onychophagia) or breaks off (trioxepane) and pull (trichotillomania) hair, which leads to the formation of small plots of depression hair without clear boundaries and without inflammation, usually in the frontal and temporal areas; biting his lips (halfaya), irritate the skin itches (dermatology).
The fears of getting any dermatosis (scabies, bromidrosis or other) - dermatophone forces the patient to intensively use of various disinfectants, which often leads to the development of dermatitis. Conscious (pursuing a certain goal) or unconscious (attached as reflex) the desire to hurt himself the skin of the different chemical, physical or other irritants, simulating a disease of the skin, called dermatopathia. Such artificially induced dermatitis have a uniform shape and form (bubbles, areas of necrosis and other) with a focal location on available for manipulation of the patient.
In the treatment of psychogenic diseases of the skin along with hypnosis, psychotherapy, neurologicznej and sedatives important observation as a doctor, middle and Junior medical staff at the behavior of the patients. If trichotillomania - the imposition of zinc-gelatin headbands, caps or shaving of the hair.

Psychogenic diseases of the skin. Various emotions can cause temporary or permanent vascular, secretory, trophic reactions: episodes of anemia, skin, erythema shame, loss and graying hair, exacerbation of eczema or psoriasis and other Patients with neurosis (see) often suffer from eczema, urticaria, neurodermatitis, and worsening neurological and dermatological symptoms such patients often a natural match.
Among a variety of somatic disorders in hysteria observed lesions of the skin in the form of blisters, blisters, hemorrhage, and necrosis. Description this kind of "stigma" is especially common in old psychiatric and dermatology literature. Currently, these phenomena are considered a consequence of self-harm, which cause them secretly, but for demonstration purpose patients (see Hysteria, hysterical dermatitis). However it is possible and real opportunity psychogenic in the true sense of this word origin hysterical dermatoses. So, if the patient hysteria suffers from hemorrhagic diathesis and it's easy to get hemorrhage using a mild injury to the skin (friction, pressure), then such hemorrhage can occur as a result of auto-suggestion. Those or other damage to the skin, they had last in patients with hysteria, can at the height of hysterical attack to be repeated by the mechanism of conditioned reflex.
Compulsive actions and fears (see the Obsessions) are often accompanied by pathological skin changes. Dermatologii - uncontrollable obsession to cause damage to the skin and its appendages: trichotillomania (pulling hair), onychophagia (persistent habit of nail biting), halfaya (lip-biting), etc. Perhaps one of the reasons of such dermatology is the presence of paresthesia (false perceptions). Germanophobia - obsessive fear of any skin disease: acrophobia (fear mites); bacteriophobia; acneby (fear of acne); prometropole (fear stinking of sweat stop). Such patients are not confined to one's fear of the disease, but begin to injure the skin, vytsarapyvajut of her alleged mites, seeking out and squeezing alleged acne, vigorously rubbing into the skin of various disinfectants. The result is often dermatitis, and this is even more wrong supports obsessive view of the patient.
Simulation of dermatoses (dermatopathology) can be conscious (the man has a purpose) or unconscious. Sometimes simulation, motivated by curiosity, subsequently secured as pathological reflex. Artificially cause blisters, burns, bruises, etc., With the aim of getting them used different drug or domestic stimuli (acids, alkalis, application of a hot object, mechanical damage).
Thus, if we exclude conscious simulation acts mentally healthy people, skin diseases caused by disorders of the Central nervous system, can be viewed either as manifestations of psychogenic caused by autonomic disorders and disorders of trophism of the skin or as a result of active self harm that mentally ill put yourself under the influence or obsessive, especially in schizophrenia, delusional views.
Diagnostics psychogenic diseases of the skin is based on careful observation of patients, of whom one must not suspect, and on the peculiarities of skin symptoms (localization on the skin, easy to its damage, sharp edges, unusual shape, and so on).
