Psoriasis Types

Psoriasis is a complicated disease with no single cause. It is known that a number of factors can cause the disease from genetics, the environmental creating a breakdown of the immune system. This can be triggered by a number of factors from:-

Psoriasis

. stress

. skin injury (Koebner phenomenon)

. medications

. climate

. infection

. smoking

These triggers can result in the immune system breaking down creating several forms of Psoriasis. Here is a list of the five most common types of Psoriasis:-

. Plaque Psoriasis.Guttate Psoriasis

. Inverse Psoriasis

. Erythrodermic Psoriasis

. Pustular Psoriasis

Each type has its own unique characteristics; some types can occur alone or combined with other forms. Therapy can differ for each.

The most common form of Psoriasis is Plaque Psoriasis –

A raised area of skin that is more than 1 cm in diameter is given the term “plaque” . Although smaller areas of raised skin less than 1.0 cm (papules) might be present. Smaller papules may join to form a larger plaque. The affected area is normally raised, red and scaling.

Guttate Psoriasis

Guttate psoriasis patients often describe the sudden appearance of small (2-3 mm in diameter), raised, scaling bumps. Possibly starting in childhood or teenage years after streptococcal infections of the throat such as tonsillitis (streptococcal pharyngitis). A sudden influx of many tiny red, raised bumps (papules) covering large areas of the body can begin two to four weeks after the illness. Many lesions can increase and spread rapidly over the trunk, arms, legs, and possibly the face.

Inverse Psoriasis

As well as being known as flexural psoriasis it affects areas where the body such as folds. The skin in the armpits, groin, under the breasts, and in the perianal location. This type of psoriasis usually begins along with plaque-type psoriasis but can occur on its own. Different from other types of psoriasis, rather than appearing scaly, the skin is smooth, moist, and salmon colored. Inverse psoriasis can be confused with a yeast (candida) or fungal infection (jock itch).

Erythrodermic Psoriasis

This is a nasty form of psoriasis known as Erythrodermic psoriasis. Also known as exfoliative psoriasis, because of the scaly lesions that cover most or all of the body the skin can be scaling and peeling. Observed by widespread, extremely red, itchy and swollen skin and sometimes the skin can be very red with minimal scaling. Areas of raw skin, pustules might be present and pus can ooze from these lesions. The eyes, the inside of the mouth and the lining of the nose can also be affected.

Pustular Psoriasis

Pustular psoriasis can be seen by the appearance of small blister-like areas of non-infected pus on the skin. Pustular psoriasis can be observed in two forms: localised (often only the hands and feet) and generalised (extensive areas of the body). Localised, or palmoplantar pustulosis (PPP), is the most popular pustular form. People with generalised pustular psoriasis (GPP) are amongst the most seriously ill and will normally need hospitalization until the psoriasis is under control. Pustular psoriasis can be triggered by smoking , infections, stress or certain medications.
