This is a type of autoimmune pathology, which translates into a failure of the immune system, this system is in charge of defending against pathogenic microorganisms (viruses, fungi, parasites and bacteria), and is made up of different cells such as lymphocytes, monocytes, neutrophils and basophils, which will recognize and act against all infecting agents that wish to attack the human body; autoimmune diseases are caused by a failure in the recognition of the body's own structures, by the defender cells belonging to the immune system.
In the case of psoriasis, the lymphocytes do not recognize the cells that make up the skin tissue, progressively degrading them and therefore the body accelerates their production in search of compensating for the lost tissue, but the body does not accelerate the expulsion of these skin residues causing a constant flaking appearance. According to the fact that its origin is due to an immune problem, this disease is 0% contagious, that is, its spread is not achieved by direct contact, the main cause being the genetic factor, which has led to the genetic analysis of the patients to define what is the gene causing this alteration in the skin.
This pathology can be classified as: erythrodermic psoriasis, where large reddish spots are observed on the skin, on the other hand there is guttate psoriasis (in the form of a drop) due to the fact that small spots are seen on the skin, in the same way the inverse psoriasis, which irritation and redness of the fold areas as the inguinal region and underarms evidence.
Patients with psoriasis have a main symptom which is the permanent appearance of residual skin plaques, with an irritated appearance, with a red coloration and a scaly appearance; the appreciation of these plaques is seen more frequently in joints with high contact, such as the knuckles, elbows, knees and at the level of the scalp, looking like dandruff that is difficult to treat.
The skin is dry, thick and pruritic, other symptoms can be lesions at the level of the nails, being thick, yellowish in color and easy to detach from the skin, arthralgia (joint pain) and sometimes lesions in the genitals mostly male.
