Scientists specializing in this skin disease have determined the pattern of diagnosing the disease by identifying different types for psoriasis . This method of division enables to characterize the possible development of psoriasis as well as select the most effective and safe way of best treatment for psoriasis.
There are a number of factors and characteristics that underline the classification of psoriasis and distinguish one type of psoriasis from another:
- size, shape and extent of psoriatic lesions
- clinical manifestations of psoriasis
- localization of damaged areas
- development stage and severity degree
- seasonality of exacerbations
With the help of these criteria it is possible to distinguish clinical varieties of psoriasis. They will help to diagnose the disease more accurately and choose individual therapy to eliminate its symptoms.
There are such types of psoriasis:
- vulgaris or common psoriasis
- reverse (atypical) psoriasis
- pustular or exudative psoriasis
- guttate psoriasis
- erythrodermal psoriasis (psoriatic erythroderma)
- arthropathic psoriasis (psoriatic arthritis)
- nail psoriasis (psoriatic onychodystrophy)
- scalp psoriasis
Depending on the development stage of psoriasis, there are 3 forms of it:
Depending on the seasonality, there are such types of psoriasis:
- winter type — manifested during fall-winter period
- summer type — aggravates during spring and summer period
- mixed or all-seasonal psoriasis — the symptoms are manifested depending on the season
This type is the most common among other different types of psoriasis. It's often called classic, plain or plaque psoriasis. According to the statistics, this type of psoriasis is observed in almost 90% of patients. For this type purple inflamed spots jutting out over the skin surface are typical. They are covered with several layers of white-gray flakes that can be peeled off easily. The affected areas of the skin may slightly bleed if injured. The typical for classic psoriasis skin lesions described above are called psoriatic plaques. The causes of the development of vulgar psoriasis are diverse in their nature. To date, doctors specializing in this disease can not state certainly what factors triggered the disease. However, there are a number of theories that can be considered as the causes of common psoriasis, namely: genetic predisposition, disorders of the endocrine system, pathological changes in metabolism and psycho-emotional stress. As a rule, psoriasis vulgaris develops gradually. It is most widely spread on hand (psoriasis on hands). Sometimes patients can observe sudden psoriasis emergence. At first, there are pinkish-red inflammatory foci which are rough and covered with silvery scales. These psoriatic plaques tend to have a rounded shape, but their size may vary. Basically, such lesions are concentrated on a single area on the body. It can be: hands (psoriasis on hands), feet, elbows and knees, scalp, the back, and so on. Depending on the extent of the damaged skin, the degree of inflammatory process and the general condition of the patient, common psoriasis severity degree is represented by:
- light course;
- medium course;
- severe course;
The degree of psoriasis is determined by the severity index of lesions of psoriasis (PASI) The treatment of plaque psoriasis is a difficult and long process. If the therapeutic methods were not selected correctly, it is possible to observe the progression of psoriasis. In case of a sudden stop of the treatment process, especially if the treatment was carried out with hormonal drugs, there may be exacerbation. Such complications can cause sepsis which is very dangerous for human life. Therefore, it is better to conduct treatment under doctor's supervision as well as choose the best cream for psoriasis.
Reverse (atypical) psoriasis
This kind of psoriasis is one of the most complex forms of psoriasis. It includes psoriasis on the folds of the skin (armpits, inguinal area, and others) as well as lesions of the genitals. Reverse psoriasis can occur at any age. It does not depend on the gender and this is why it emerges in women and men. It is characterized by a chronic course of exacerbation being replaced by remission. The most frequent relapses are observed during autumn and winter. damage varies from minor rash to large lesions.
Psoriasis of genitalia - signs of this type of psoriasis are rashes on genitalia (labia, penis). They are manifested through pink and red spots, without typical peeling. Therefore, diagnosing psoriasis of genitalia is hard. Nevertheless, the disease brings a lot of unpleasant feelings and psychological discomfort. The factors that cause this type of psoriasis can be diverse: psychological problems, in particular (stress, nervous tension, injuries of the psycho-emotional plan), heredity, disorders of the immune system, pathology.
Intertriginous psoriasis (psoriasis on skin folds) - like psoriasis of genitalia, this type doesn't cause peeling of the skin layer. Diagnosing intertriginous psoriasis is not easy since the symptoms are similar to other diseases, such as mycosis. Skin damage has borders, red-pink color and smooth surface. The process of treating this atypical psoriasis is very difficult. The places of skin damage are extremely sensitive. This type of psoriasis often has a stage of wetting, lesions can be infected which causes pain and causes considerable discomfort to the patient. In addition, plaque can be easily damaged by underwear or clothing. In this case, complex psoriasis natural treatment is a prerequisite since topical therapy is ineffective. But long remission can be achieved if the therapy has been chosen properly.
Pustular or exudative psoriasis
This type is manifested through the most severe pathological changes. Characteristic signs of this type are purulent lesions of the skin. Pustular psoriasis can be caused by infections, pathologies of the hormonal background or by improper treatment of common psoriasis. This disease often causes a fever, an increase in blood leukocytes. Skin lesions form purulent lakes which is accompanied by burning and painful sensations. Patients with exudative psoriasis have the need for hospitalization during exacerbations. The process of treating this form of ailment is very complex, long and it requires special attention. However, the cyclicity of the disease implies the possibility of remission. There are two forms of pustular psoriasis: generalized and localized.
Generalized form of pustular psoriasis is dangerous for human life. Rapidity of the symptoms development is typical for this type. At first, you can see inflamed foci, in the form of purple spots on the skin. Over time, they are transformed into purulent lesions and merge into large-scale skin lesions. If these lesions are injured, there are wounds and ulcers. This form of the disease is accompanied by severe itching, burning and febrile syndrome. The disease aggravation can last almost 2 months. As a consequence, the skin shows symptoms typical for common psoriasis. Localization: elbow and knee folds, skin folds, genitalia and sometimes head and nails.
Localized form is one of the most common manifestations of it is the palmar-plantar psoriasis. This form of the disease is localized on the lower part of the feet and palms. The first signs of this type of psoriasis are red spots on which pustules with purulent filling are formed. Often, the skin around the affected areas coarsens, there are cracks. Treatment of a localized form can be carried out with the help of topical medications: ointments, creams, and sprays. Vitamin intake as well as antihistamines and immunomodulators is quite useful as well as psoriasis cream.
Most often it develops in children and young people but can affect people of any age. In most cases, the cause of guttate psoriasis can be a transmitted infectious disease. This form of psoriasis can manifest itself within 15 to 20 days after the first sign. Most often, it emerges on face (psoriasis on face)The localization of guttate psoriasis can not be foreseen. Papules can appear anywhere except for the face. It can be arms or legs, back or chest. Lesions are characterized by the suddenness and high severity of manifestation. The symptoms can be eliminated but taking into consideration that psoriasis is a chronic disease, there are possible relapses. If the treatment is delayed, the papules caused by the disease increase in size and damage the healthy areas of the skin. Thus, the disease takes a severe form.
This type is the most dangerous comparing to other different types of psoriasis. It is extremely rare and occurs due to exacerbation of psoriasis. In most cases, it emerges on the face (psoriasis on face) Erythrodermal psoriasis is more common in men and manifests itself during fall and winter. Experts divide it into patimary and secondary. Primary erythroderma emerges in healthy people and secondary is the result of a skin disease (in this case, psoriasis). Depending on the symptoms, there are generalized form (occurs due to the long development of psoriatic lesions) and hyperergic (typical signs are the rapidity of development and sudden deterioration of the general condition of the patient. The latter form causes swelling and redness of the skin accompanied by peeling, burning, itching, pain and even hair loss. Depending on the distinctive features of psoriasis course, it can be acute, subacute and chronic. The latter can be accompanied by other skin diseases (mycosis, leukemia, reticulosis). Since this form causes dehydration, fever and metabolic disorders, it is necessary to hospitalize the patient as soon as possible. Treatment can be conducted by a doctor only, stationary therapy in the hospital i recommended.
This type of the disease is characterized by inflammatory process in the joints. It has an autoimmune nature as it is triggered by psoriasis. This disease emerges a few years after the appearance of first psoriasis symptoms. The most commonly affected are middle-aged and young people and it“s very rarely found in children. Of the 100 people suffering from psoriasis, about 38 people have psoriatic arthritis. Arthropathic psoriasis manifests itself through joint damage. It mostly affects interphalangeal, knee and ankle joints. This is a very severe illness. If you do not follow the necessary treatment, it can lead to a physical disability. The treatment consists of the correct diet, medical therapy and physiotherapy. If there are strong joint deformations, it is necessary to eradicate the affected areas as soon as possible.
This type affects nails. It occurs very often. It can emerge with cutaneous lesions or without. The main symptoms are a nail plate color change, thickening, delamination, nail brittling and separation of the nail from the nail bed. The first signs of psoriatic onychodystrophy are shallow point formations, then transverse and longitudinal sulcus lines appear. If no treatment is conducted, there can be a permanent loss of nail platinum. Factors that can provoke this form of ailment may be: immune system imbalance, hormonal failures, metabolic disorders, stress and infectious diseases. To treat psoriasis of the nails, complex therapy should be used. This is a long process but this can help you restore your looks and get rid of unpleasant feelings.
The most common among different types of psoriasis is scalp psoriasis. The main symptoms of scalp psoriasis are red inflamed spots on the scalp covered with silver crusts with severe itching and peeling. Like all different types of psoriasis, including psoriasis on hands, this disease has a chronic nature. Exacerbations are replaced by remissions. The causes of psoriasis may be heredity, transmitted infections, digestive dysfunction, psycho-emotional stress, the effect of very low temperatures on the scalp, as well as various scalp injuries lack of healthy eating and bad habits. Scalp psoriasis treatment requires a complex approach. Moreover, treatment for scalp psoriasis has to be carried out under the supervision of a doctor as only a specialist can determine the stage and severity and prescribe the appropriate treatment. The wrong treatment or self-medication as well as folk medicine can be dangerous for your health and even lead to a psoriasis exacerbation.
