Psoriasis: causes, symptoms and treatment of scaly lichen

Psoriasis (squamous lichen) is a chronic non -communicable skin disease. It affects both men and women. According to statistics, 4–5% of the world's population suffers from pathology.

Psoriasis can start at any age, but is more often diagnosed between 18 and 25 years of age. In this case, the first signs of lichen skin appear earlier. The disease significantly reduces the quality of life of patients, causing many difficulties and causes of depression.


Currently, the cause of psoriasis is not yet known. Doctors consider two main options that lead to the development of skin diseases:

  • autoimmune disorders in the body. In this case, the lymphocytes responsible for the immune response are out of control, becoming aggressive and invading their own tissues;
  • failure of the normal process of multiplication of skin cells (keratinocytes). The result of pathological changes, again, is an attack of lymphocytes, which protect the body from infection.

The following factors can cause excessive cell growth and immune imbalance:

  • genetic inheritance;
  • allergic skin rash;
  • dermis thin, dry, sensitive;
  • constant contact with chemical irritants;
  • newly transplanted fungal and staphylococcal diseases;
  • excessive enthusiasm for hygiene procedures;
  • Take antidepressants, antimalarial medications, or beta blockers
  • common skin damage in one place.

If there is a predisposition, psoriasis in adults can occur under the influence of momentary stress or prolonged emotional and physical stress.

Recent scientific research has revealed new causes of the disease:

  • squamous lichen often occurs in carriers of intestinal parasites. A direct link was found between worm invasion and the occurrence of skin lesions;
  • the cause of skin psoriasis is often a lack of silicone in the body. This pattern was confirmed by analysis of the patient's blood spectrum.

The two dots are interconnected with each other, as the worms actively absorb almost all the silicon that enters the body.


In medical practice, it is customary to distinguish three degrees of severity of psoriasis. With a small amount of scaly lichen, less than 3% of the skin is affected. The middle stage of psoriasis is characterized by a high prevalence of psoriatic plaques - in this case, they occupy 4-10% of the dermis. In severe disease, the joints are involved in pathological processes, and more than 10% of the skin is affected.

In addition, psoriasis can be both pustular and non -pustular. What is the meaning? For pustular (exudative) skin lesions, abrasions with purulent contents are characteristic. This type of disease includes the following types of psoriasis:

  • generalized psoriasis and Zumbusch species;
  • palmar-plantar psoriasis or Barbera;
  • annular psoriasis;
  • acrodermatitis Allopo.

Types of non -pustular psoriasis (common):

  • plaque lesions;
  • erythrodermic type (occurs as a complication of mild psoriasis).

Skin lichen vulgaris occurs in 90% of cases. It is not difficult to determine - it is a vulgar form with a stable course and symptomatic features of psoriasis. With the transition to the erythrodermic stage, the progression of the disease becomes complicated.

In addition to those considered, there is also psoriasis, which develops against the background of medication intake, psoriasis such as seborrhea, lichen skin folds and flexor surfaces, Napkin psoriasis.


psoriasis of the head

Scaly lichen is a systemic lesion of the whole body. It not only affects the skin, nails and hair, but also the joints, immune and endocrine systems. Patients complain of constant lethargy, depression, irritability.

The symptoms of psoriasis are wavy in nature, with periods of remission and worsening. The severity of the lesion is constantly changing and in the same patient can range from slight redness to itchy plaques that cover the entire body.

How to distinguish psoriasis from other skin conditions? There are classic symptoms that exist only for this disease:

  • red spots (psoriatic plaques), raised above the skin surface by 1-2 mm and covered with dry scales resembling paraffin. They can be localized anywhere;
  • severe itching, especially during exacerbation of psoriasis;
  • exfoliating nails left behind in bed;
  • bleeding (blood dew) at the site of plaque detachment;
  • skin pain, cracking and dryness.

If arthritis symptoms are added to herpes zoster, pain and swelling in the joints are observed.

There are 3 stages of psoriasis:

  1. Progressive.During this period, new plaques actively appear, existing ones increase, itching and severe exfoliation.
  2. Still.It is characterized by stable conditions. The growth of the formation becomes slow, dry scales appear on the plaque.
  3. Regressive.Itching and peeling stop, the spots turn whitish, the remission period begins.

The degree of cutaneous lichen is based on the season (in winter, the disease develops more actively) and the severity of the inflammatory process. That is, the faster the irritation, especially in stage 1 psoriasis, the stronger the body’s response in the form of the appearance of a new rash.

Their forms and symptoms

The symptoms of psoriasis vary depending on the location of the lesion and the stage of the disease. In many different types of diseases, symptoms can carry the most unexpected combinations and different intensities.

What is psoriasis like in various forms? For example, the scalp causes severe dandruff -like skin. It is localized on the forehead, behind the ears and in the scalp area. The shape of the nail is characterized by poor nail condition: brittleness, stratification, tuberosity.

The most common type of skin psoriasis is plaque psoriasis. It is registered in 93% of patients. It is indicated by the presence of red spots found all over the body: on the head, back, elbows, knees and chest. A type of psoriasis of tear -shaped plaques. For him, a small, dry, red papular rash that resembles a droplet is common.

The most severe forms of psoriasis are atrophic and exudative. The first affects the joints of the arms or legs. Arthritis of the knee and hip joints can be so severe that it leads to a wheelchair.

With exudative psoriasis, fluid -filled blisters (pustules) appear on the surface of the skin. Their damage often leads to the development of purulent processes that require complex treatment. In severe cases, pustular lesions spread throughout the body and become generalized.

Is psoriasis contagious?

Is psoriasis contagious? Psoriasis is an individual characteristic of the body that appears against a background of autoimmune disorders, and is not the result of exposure to bacteria and viruses. Numerous studies and practical experience have proven that lichen skin is completely safe, and the presence of similar family members with psoriasis symptoms only confirms the theory of genetic inheritance.

Which doctors treat psoriasis?

If you suspect psoriasis, you should first see a dermatologist, as he is the one who deals with skin diseases. If for some reason this specialist is not present at the local clinic, the coupon for the therapist should be deferred. This is a general practitioner who can also diagnose and prescribe psoriasis treatment. If skin lichen is complicated by pain in the joints, you need to see a rheumatologist.


doctor's examination for psoriasis on the feet

The diagnosis of skin psoriasis is simple and, as a rule, based on external signs of the disease. Specialists perform a visual examination and reveal changes in the dermis that are just a hallmark of scaly lichen.

If the pathological picture is not clear enough, and that is how psoriasis, which is just beginning to develop, the patient will undergo additional studies, for example, skin biopsy. If there are complaints of pain and swelling in the joints, x-rays and blood samples are taken for general analysis.

In recent years, hemoscanning has become widespread, requiring only one drop of blood. Doctors say that this procedure will help not only identify scaly lichen at an early stage, but also track the effectiveness of therapy. However, hemoscanning should be complemented by external examination and other diagnostic methods.


The process is very individual. Therapy should be performed only by a qualified physician, depending on the symptoms, the presence of concomitant pathology and the influence of environmental factors. The success of treatment is highly dependent on the age of the patient, his profession, gender and the degree of psoriasis.

The available techniques are based on increasing the effect of drugs on the patient's body. The course begins with a more gentle local agent with a number of adverse reactions. If they don’t help, pills are introduced into the scheme.

Consider the main methods of treating psoriasis

Systemic therapy

It is used for moderate to severe skin lichen. Includes the following drug groups:

  • hepatoprotectors;
  • antihistamines;
  • glucocorticosteroid medications;
  • cytostatic;
  • MAT (monoclonal antibody);
  • immunosuppressant;
  • vitamin A derivatives.

Specific treatment in adults is complemented by symptomatic therapy. If necessary, a patient with psoriasis is given antifungal or antibacterial medications, drugs that increase metabolism and calm the central nervous system.

Local therapy

Treatment for psoriasis includes the use of various gels and creams. In the early stages of skin disease, non -hormonal formulations are used. If they do not give the expected effect, patients are given a mild hormonal ointment, then they switch to stronger glucocorticosteroids.

It is believed that the most effective remedy for skin psoriasis is a solidol -based cream.

All hormone ointments are used only as directed by the doctor and after reading the instructions carefully.

Treatment of scaly lichen on the head

How to get rid of psoriasis on the head? Healing shampoo gives a good effect. To avoid addiction, they are replaced every 2-3 weeks.

Before using the cleanser, salicylic ointment or 2% cream mask is applied on the scalp. Between water treatments, hormonal tonics are used.

Local preparations for psoriasis are used in combination and only after consultation with the attending physician. In severe cases, the patient is prescribed physiotherapy procedures: ultraviolet irradiation, UV comb, photocotherapy.


It is very important for people with psoriasis to follow a diet. Various deviations from the recommended diet can exacerbate psoriatic disease.

The menu should contain foods rich in silicon, lecithin and vitamin D. It is recommended to eat fish or white meat 3-4 times a week and prefer lactic acid products. In addition to a balanced diet, it is good to drink fish oil several times a year.

Can psoriasis be completely cured?

Can psoriasis be completely cured? Unfortunately, today, skin diseases are unbeatable. Psoriasis has a chronic form, slow and develops slowly. The prognosis is not always conducive. Various treatments for skin psoriasis temporarily improve the patient’s condition, but do not result in full recovery.


Preventing skin psoriasis is difficult and easy at the same time. The difficulty lies in the fact that various factors can provoke the development of pathology, especially with genetic predisposition. At the same time, there are a number of simple steps that can protect you from skin diseases, and with psoriasis already arising, reduce symptoms.

Key precautions:

  • increase immunity, do physical education in the fresh air, harden;
  • efficient and complete facial and body skin care, including cleansing and moisturizing. For water procedures, it is recommended to use a soft cloth and a neutral gel;
  • strict sunlight exposure. Ultraviolet light in moderate amounts strengthens the skin and increases its resilience, while the excess causes damage to the skin and exacerbation of psoriasis;
  • synthetic things should be avoided. It is best to buy clothes made from natural fabrics that do not cause allergies. The same goes for beds;
  • any injuries and damage to the skin (calluses, diaper rash) must be healed immediately and completely;
  • you can’t get carried away with aggressive cosmetics and using creams that have expired. When using household chemicals, gloves should be worn, and, if necessary, a mask;
  • it is very important to avoid stress, emotional surges and overwork. This is a moral factor that is often the main provocateur of skin lichen.
hardening as a way to prevent psoriasis

Prevention of psoriasis involves the intake of vitamin complexes with increased content of ascorbic acid and immunostimulants.

If the pathology has developed, you should pay attention to nutrition. Exclusion from the diet of fine and sweet foods, smoked meats, marinades and alcohol in more than one -third of patients eliminates the manifestations of skin lesions.

Despite the long and difficult treatment of psoriasis, it is impossible to completely beat it. But compliance with all doctor's prescriptions and implementation of preventive measures will ensure remission for many years.
