 Plaques
The plaques psoriasis is the most typical form of the illness,
four among five people have this kind of psoriasis. A " plaque
" is the name used to describe the very defined formations of
the red, lifted skin, and the word " lesion " is also commonly
used. The technical name for the psoriasis in plaques is “ psoriasis
vulgaris.
" The scaly, white and plated accumulation above the plaques
is so-called “flake”; it is composed by the skin dead cells.
This flake is almost loose and is constantly detached from the
plaques. The skin affected with psoriasis is generally very
dry. Other possible symptoms include cracking, pain of the skin,
itching.
 Guttate
(drop by drop)
The guttate psoriasis is similar to small, red, individual drops
in the skin (the word guttate comes from the Latin meaning "
drop "). These lesions generally appear in the trunk and
the members, and sometimes in the scalp, and they are not contained
thickly and don't scale as the psoriasis in plaques. The guttate
psoriasis often begins in the childhood or in the puberty, and
it can be worked by an infection. .Getting back

 Inverse
The inverse psoriasis, also called Flexural psoriasis is presented
in the axillas, groin, under the breasts and in other skin folds
around the genital organs and the buttocks. This kind of illness
is presented like flat areas, dry skin, red and inflamed areas,
but they don't have the flake associated to the psoriasis in plaques.
The inverse psoriasis is related with the irritation for rubbing
and to the softening due to its localization in skin folds and
in soft and humid areas. It is very common and annoying in fat
people.
 Erythrodermic
(skin reddening)
The Erythrodermic psoriasis is a certain way of inflammatory psoriasis
that often affects most of the body surface. It is the less common
kind of the illness. It appears very commonly in people with unstable
psoriasis in plaques, where the lesions are not clearly defined.
The Erythrodermic psoriasis is characterized by the constant,
extensive, and burning skin reddening. The skin erythrodermic
(reddening) and the exfoliation (shedding) are often accompanied
by skin itching and severe pains. It can be also become in swelling.

 Widespread
pustulous
This is so-called to the body wide areas spread by pustulous psoriasis.
The first doctor who described it was Von Zumbusch in 1900. In
this relatively strange form of illness, the spread areas of the
red skin (erythema) are transformed and developed. The soft skin,
pustules, non infectious ampoules of pus and can change and appear
as dry skin, and can be sharp and painful and later it reappears
the soft and pustulous skin for several days.
 Located
Pustules
Generalized Pustular
Pustular psoriasis spread over wide areas of the body is also
called
von Zumbusch pustular psoriasis, named after the physician who
first described it in the early 1900s.
In this relatively rare form of the disease, widespread areas
of
reddened skin (erythema) develop, and the skin becomes acutely
painful and tender. Pustules—blisters of non-infectious pus—may
appear on the skin, dry, then reappear in repeated cycles lasting
several days.
Localized
Pustular
Pustules of psoriasis can be confined to local areas, particularly
the hands and feet. The form called palmo-plantar pustulosis (PPP)
is characterized by large (up to .5 cm, or about the size of a
pencil
eraser) pustules in fleshy areas of hands and feet, such as the
base of the thumb and the sides of the heels. The pustules appear
in a studded pattern throughout reddened plaques of skin, then
turn brown
and peel.
Another rare form is called acropustulosis (or acrodermatitis
continua of Hallopeau). In this type, skin lesions develop on
the ends of the fingers and sometimes the toes. The lesions can
be painful and disabling, with nail deformities and, in severe
cases, changes to the bone. Getting back above
Measuring
the Severity of Psoriasis
Psoriasis is divided into three degrees of severity: mild,
moderate and severe. Abou75 percent to 80
percent of people with psoriasis have what is considered mild
disease, and about 20 percent to 25
percent have moderate to severe psoriasis. These categories are
useful for selecting what treatments
might be appropriate for individuals with psoriasis. The physical
measure of severity is based on how much skin on the body is affected
by psoriasis. As a general rule of thumb, the palm
of the hand represents 1 percent of the body's surface. Severity
can also hinge on how psoriasis affects a person's quality of
life. If psoriasis covers only a small area yet is serious enough
to be disabling—for example, bad psoriasis of the hands or
feet—it could be considered a severe case of the disease.
 Mild
Psoriasis
People with psoriasis on less than 2 percent of their body are
considered to have a mild case. Generally, isolated patches of
psoriasis are found on the knees, elbows, scalp and hands and
feet. Topical treatments—including moisturizers and over-the-counter
and prescription creams, ointments and shampoos are usually sufficient
to keep the psoriasis in check.

 Moderate
Psoriasis
Moderate psoriasis is defined as affecting between 2 percent and
10
percent of the body's surface. Psoriasis may appear on the arms,
legs, torso, scalp and other areas. Appropriate therapies include
topical treatments, phototherapy and oral medications, depending
on
the location and extent of the
psoriasis and other individual factors.
 Severe
Psoriasis
Psoriasis covering more than 10 percent of the body is considered
severe. Extensive areas of skin may be covered with psoriasis
plaques or pustules, or widespread erythrodermic psoriasis (as
shown in the photo to the left) can cause severe peeling of the
skin. People with severe psoriasis are more likely to develop
psoriatic arthritis.
Powerful treatments, including phototherapy, oral medications
or a
combination of these, are usually necessary to manage severe psoriasis.
