Types of pseoriasis

Psoriasis is a chronic skin disease characterized through the apparition of red wounds, well defined, containing scales and are located in different parts of the body. The scales are thick, pearly-white, adherent to the skin and easily detachable, in the form of lamellae. The disease occurs to approximately 2-3% of the population.
Psoriasis mainly affects some areas of the body, including: scalp, elbows, knees and back. More rarely, armpits, palms and soles (soles) are achieved. In 50% of cases, psoriasis can be localized at the nail level, which thickens and peel, becoming greenish.
Symptoms range from milder forms and reach truly harrowing manifestations (eg, those located in the folds of the joints). On the other hand, the severe forms of psoriasis give rise to  emotional manifestations, the affection, having a negative impact on social relations, personal and emotional. Patients are sometimes so overwhelmed by their illness that they feel isolated and depressed.
The cause of psoriasis is unknown, but one of triggering factors include trauma, infections and certain medications.

Diagnosis is based on the appearance and distribution of lesions. Treatment consists of the use of emollient creams, vitamin D, retinoids, corticosteroids, phototherapy, and in severe cases, methotrexate or immunosuppressive drugs.
Distribution of incidence according to age is bimodal: the first peak occurs in 16 to 22 years, and the second between 57 and 60 years.
Signs and Symptoms
Depending on the look and location of wounds can be defined several types of psoriasis. The most common form is vulgaris psoriasis. Other types are guttate psoriasis (droplets), reversed, erythrodermic and pustular.

Psoriasis vulgaris - is characterized by the presence of red wounds, well-defined, round or oval, covered by thick crusts, white which to peel. They are in general located on the elbows, scalp, knees and buttocks.

Guttate Psoriasis - is manifested by the sudden appearance of the wound with a diameter of 0, 5 -1, 5 mm, especially on the trunk in children and young adults. This form of psoriasis is caused by another disease or medications (eg strep throat)

Psoriasis reversed - the wounds occur inside the joints (in the axillary region, inguinal, near the genitals) and are more wet than dry and sometimes become painful because they are subject to friction.

Erythrodermic psoriasis - is characterized by progressive or sudden appearance of a diffuse erythema (almost all surface of the skin is red and inflamed), and psoriatic wounds are less prominent or even absent. Erythrodermic psoriasis frequently appears in patients with vulgaris psoriazis due to inappropriate use of topical corticosteroids or systemic or phototherapy.

Pustular psoriasis - characterized by the presence of wounds covered by white pustules, especially on the palmar and plantar surfaces.
