Plantar psoriasis accounts for 25% of all skin diseases, it affects the soles of the feet, which seriously complicates the treatment. This is a long-lasting (several years) non-infectious process. It is accompanied by pain and severe itching, which causes not only physical suffering, but also psychological discomfort. The root cause of plantar psoriasis can be a common skin injury.

Causes of the plantar psoriasis

The following factors contribute to the occurrence of psoriasis manifestations in the plantar area:

  • Heredity.
  • Malfunction of the immune system
  • Infectious diseases.
  • Physical trauma of the skin.
  • Prolonged treatment with antibiotic drugs.

In our time, doctors tend to believe that the appearance of psoriasis has a relationship with malnutrition. Pathology can be a consequence of disturbed protein and lipid exchanges occurring in the intestine. During the remission the amount of toxic substances decreases.

Pathogenesis

At this time, the etiology of psoriasis is unknown. Specialists identify 2 main hypotheses regarding the origin and nature of pathology.

The first one connects the appearance of plantar psoriasis with disorders in the maturation and differentiation of the cellular epithelium. The problem arises when the functioning of the upper layer of the skin and its cells is disrupted.

Supporters of another hypothesis believe that the appearance of psoriasis is of an autoimmune nature, in which strong growth and proliferation of skin cells, especially keratinocytes.

Symptoms of the plantar psoriasis

Symptom complex of manifestations is as follows:

  • the skin in the area of the palms and feet becomes thicker;
  • skin affected by psoriasis dry, covered with cracks, where inflammatory processes occur, accompanied by pain;
  • on the skin of the palms and feet appear pustules with a transparent liquid, which eventually becomes white and turns into dark crusts.

The first signs of the manifestation of the disease is dryness of the skin and redness on the arches serves, hyperkeratosis of the upper part of the epidermis and cracks on it, accompanied by constant soreness. The coarse skin is affected by corolla-like growths that are fringed by an even thicker skin. Often - plaques of rounded shape, covered with scales. They are placed chaotically on the surface of the skin or merge with each other. Within the plaque, you can see pustules that are deep in the skin. These formations are of a non-infectious nature.

Stages

To make it easier to assess the course of the disease, to determine its sensitivity to a particular method of treatment, and to choose the right tactics for therapeutic measures, a clear identification of the staging is essential. The following stages of skin damage are distinguished:

  1. progressive;
  2. stationary;
  3. regressive.

The stage of progression is characterized by the onset of exacerbation of plantar psoriasis. In this period, new papules appear that merge, on the surface of the newly appeared elements, scaling occurs in the form of scales, the edges of the plaques are similar to a small hyperemic rim, the phenomenon of Kebner appears (any skin lesions become typical psoriatic plaques, and not cicatricial forms).

The stationary stage is manifested by a decrease in inflammatory skin changes: new red papules stop appearing, the growth of existing plaques decreases; flakes completely cover the plaque, the rim around the flaking elements disappears, the Kebner phenomenon is absent.

The regressive stage signals that the exacerbation of the disease is on a decline and there is a problem of preventing its aggravation. In this period, small creases and radial lines around the plaques (Voronov's rim), a decrease in peeling, the appearance of light or dark pigmentation instead of plaques arise.

The basis of staged is the intensity of the inflammatory process.

Forms

There are two types of plantar psoriasis - these are pustular and non-pustular (plaque) variants.

To the pustular type is vulgar psoriasis or an ordinary, isolated skin that damages the skin. This kind of disease can affect the skin of the palms, then it is a question of pustular palmar-plantar psoriasis. Patients with this pathology tend to thicken the stratum corneum of the epidermis (hypercaratosis). The initial stage of the disease is manifested by psoriatic plaques with a scaly surface, inside which there are small vessels, with trauma easily bleeding.

Pustular palmar-plantar psoriasis of Barber. Sign of the disease is the appearance of the primary element - a bubble filled with liquid contents. The skin near it inflames and thickens, a partial detachment is possible. This kind of psoriasis is difficult to treat. In addition to the characteristic eruptions, there is peeling and unbearable itching, nail plates are affected.
