Psoriasis is a non-transmissible, chronic skin condition that produces a build-up of skin cells in a very short period of time. This rapid build-up of cells induces plaques of thickened scaling on the skin’s surface. Typically, psoriasis skin scales develop in thick red patches and sometimes whitish-silver in color. It is very common in this condition to have inflammation, itching, and redness around the patches. The extreme psoriatic condition causes blisters, pus, cracking of scales and bleeding. The life cycle of a skin cell is normally one month but in psoriasis, the process of skin cells production speeds up effectuating cells to grow deep in the skin and rise to the surface. In time, they fall off. Areas of the body that effects by this condition are joints of knees and elbows but in severe cases, it may develop any part of the body including hand, feet, neck, face, scalp and even genitals.
Causes of Psoriasis
The exact cause of psoriasis remains a mystery till now but doctors have pointed out some of the reasons which indicate the possibility that leads to this condition such as genetic predisposition and environmental factors. It is very common for psoriasis, to transfer from genes to genes and to be found in members of the same family but the good news is, approximately 2 to 3 percent of the people are to be found dealing with this condition. Another possible cause is a defect in the immune system, the white blood cells called T cells mistakenly attack healthy skin cells instead of odd bacteria and infections.
The Different Types of Psoriasis
Following are the five types of psoriasis known to be common along with their characteristics and symptoms. However, not every person will experience the symptoms given below.
It is a common form of the inherited inflammatory disease and 80% of the people are having plaque psoriasis. It is non-contagious immune dysfunction condition, which proliferates as red patches covered with whitish-silver scales or red-bumps generally joined together into inflated plaques of the skin. Scalp, knees, elbows and lower back are the areas on which plaque psoriasis appears. These inflamed patches are painful and itchy. But sometimes, these patches crack and bleed. Stress, skin sensitivities, and specific medications trigger this disease and makes it more serious.
- Raised, inflamed patches on the skin.
- Itching and burning sensations around patches.
- Scaly skin that may crack and bleed.
- Silver-white scales on the patches.
- Painful, swollen joints.
Guttate comes from a Latin word “gutta” which means drop. Guttate psoriasis is the red-pink papules on the skin. It is characterized as multiple discrete tiny scaly teardrops on the surface of the skin. Lesions usually start forming during the first month of the disease and remain stable during the second month.The infection which triggers this disease most of the time is streptococcal bacterial sore throat followed by two to three weeks by skin outbreak. It is the second most common type of psoriasis and normally happens in childhood or in early 30’s. Affected areas are most likely to be arms, legs, chest, and back.
- Small salmon pink bumps.
- Drop-like lesions spread on face, ears or scalp.
- Chances of streptococcal throat infection.
- Severe itching.
This disease is not very common and it is noticeable as raised bumps like blisters can be clearly seen filled with thick fluid composed of white blood cells. Fluid is known as pus and sometimes is a sign of infection which is unknown. It causes inflammation of skin covering broad areas of back, chest and even hands or feet. In extreme psoriasis, it can be widespread and painful.Many factors may trigger pustular psoriasis including infections, systematic steroids, overexposure to UV light. Pustular psoriasis has furthermore divided types that are Von Zumbusch, Palmoplantar Pustulosis, and Acropustulosis. Doctors suggest to the patients of this disease not to drink alcohol, reduce and manage stress and try to avoid blood pressure medications as these are the triggers of disease.
- Skin becomes dry, flaky and red.
- Within hours, pustules or raised blisters appear.
- Fever and rapid pulse rate.
- Pus comes out after blisters break.
- Covers most of the body parts.
Inverse psoriasis is a type of disease which is commonly known as flexural psoriasis or intertriginous psoriasis. This disease basically affects skin folds of the body. Skin folds are areas of the body with the excessive amount of skin produced by extra body weight, where skin rubs against skin. Inverse psoriasis is a smooth rash unlike blisters, scales or bumps comparatively to other forms of psoriasis. These red lesions of rash forms in the armpits, genitals, buttocks and under the breasts of women.Due to the moist environment, people with inverse psoriasis are more likely to develop a yeast infection also in their skin folds. Just like other autoimmune diseases, the cause of inverse psoriasis is an irregularity in the immune system. However, the moisture in the form of sweat and friction of skin promotes this particular type of disease and makes it even more painful.
- Most painful and irritating.
- Severe redness of rash.
- Chances of yeast infection.
- Inflammatory rash.
- Very itchy and moist to the touch of skin.
This form of psoriasis is particularly very rare. It only affects 3 percent of the population with psoriasis but it can be very serious and long-lasting. People suffering from unstable plaque psoriasis mostly gets erythrodermic psoriasis as well because the un-stability of immune system loses its ability to control the body’s temperature and protect against infections. People who encounter erythrodermic psoriasis complain about breathing problems due to increase in their heart-rate.This disease covers most of the body’s area and lesions are not very clearly defined as it looks very similar to unstable plaque psoriasis. This disease can be life-threatening.
- Heart-rate increase and severe red rashes.
- Severe itching and pain.
- Un-stability of body temperature.
- Shedding of skin in large sheets instead of small scales.
- Covers most of the surface of the body.
