Simple or vulgar psoriasis

How does this form of psoriasis? The rash of psoriasis can have a different character, on the basis of isolated and coin-drop-shaped form of a simple psoriasis.

Coin-psoriasis - the most common form of psoriasis, which appears as a typical scaly papules - raised above the skin surface of the skin covered by silvery-white scales.

• Symptom bloody dew - in violation of the integrity of the thin film by its careful poskablivanii appear on the surface point drop of blood.

Progressive stage distinguishes the appearance of new lesions, bright pink papules surrounded by a bright and saturated neshelushaschimsya slightly vague rim, itching and appearance of fresh rash at the site of skin irritation (for example, when combing - Koebner phenomenon). Any inflammatory diseases of the skin caused by irritation (dermatitis) will also contribute to the emergence of fresh rash, dermatitis and psoriasis therefore be mutually reinforcing.

For the stationary phase is characterized by the suspension of the progression of the process - he seems to be all the time in a single pore.

During regressing stage color papules and plaques pale, their infiltration decreases and elements rashes start to dissolve. If the process starts in the middle and goes toward the periphery, the annular shape formed. Sometimes the process of resorption is in the opposite direction - from the periphery to the center to form around the plaque whitish border - psevdoatroficheskogo rim. In place of the missing white depigmented lesions formed spots - psevdoleykoderma or psoriatic Leucoderma (leucoderma - a neuroendocrine disorder characterized by the appearance of the skin, deprived of pigmentation).
