The Dermatoses (rashes)


Dermatoses (a synonym for rash) is the common name for various skin diseases.

Dermatoses include inflammatory skin diseases, various skin dystrophies, benign and malignant skin tumors, etc. The causes of dermatoses can be exogenous (external) and endogenous (internal).

The external causes of dermatoses include the following. Mechanical agents - long-term pressure, friction, bruises, etc. Physical agents - high and low temperature, exposure to ultraviolet rays, ionizing radiation, electric current. Chemical agents-acids, alkalis , etc. Of particular importance in the development of dermatoses are various infectious agents that enter the skin from the outside: bacteria , viruses, protozoa , plant microorganisms - pathogenic fungi, as well as animal parasites (ticks, larvae of the gadfly, etc.) ), blood-sucking insects, which are either the direct cause of skin diseases, or carriers of other infectious agents.

Among the endogenous etiological factors, it should be noted common infectious diseases as acute (measles, scarlet fever , smallpox, etc.), and chronic ( tuberculosis , etc.)


Often the cause of dermatoses are focal, so-called focal, infections (chronic tonsillitis , dental granulomas, etc.).

Significant role in the etiology of dermatoses is played by intoxication due to the intake of medicinal substances, as well as metabolic disorders, lack of vitamins (A, C, PP, P, B complex, etc.), circulatory disorders resulting from functional or organic vascular changes, and also the dysfunction of the glands of internal secretion . An important role in the emergence of dermatosis is played by organic and especially functional disorders of the peripheral and central nervous system.

These endogenous factors are in some cases a direct etiological factor of dermatosis, in others due to the resulting disruption of the normal physiological functions of the skin - only predisposing factors that cause the appearance of skin lesions of another etiology. An example is the often observed furunculosis ( staphylococcal infection ) in diabetic patients (violation of carbohydrate metabolism ). Finally, one should keep in mind the possibility of hereditary transmission of certain dermatoses.
