There are different types of psoriasis. Dermatologists describe that distinguishing different forms of psoriasis is dependant on what part of the body is affected, the pattern formed by the scales, how severe symptoms are, and how long they last.

Plaque Psoriasis

Plaque psoriasis is the most common type of psoriasis. Approximately 80% of people who develop psoriases are diagnosed with this form of psoriasis, which appears as patches of raised, reddish skin covered by silvery-white scale. Although the plaques can occur anywhere on the body, scalp, knees, elbows, and lower back are the parts of the body which are frequently affected by these plaques or patches.

Scalp Psoriasis

In simple terms, psoriasis can be defined as a vast acceleration of the usual replacement process of the skin. It appears as raised red patches of skin covered with silvery scales. Around the scalp margins there is thick scale and redness that is also evident. Some people who suffer from scalp psoriasis report soreness on the other hand most of the scalp psoriasis patients complain of a feeling of tightness and severe itching.

Nail Psoriasis

Nails can also get affected by Psoriasis. Affected nails can become very deformed that can lead to embarrassment of the victim. Nail plate under the cuticle is the area from where nails grow. It is involvement of the nail plate that causes ridging and pitting of the nails. Disease of the nail bed causes splinter hameorrhages, sub-ungual hyperkeratosis, and onycholysis. Rare;u.

Guttate Psoriasis

Characterized by small, droplike, 1-10 mm in diameter, salmon-pink papules, usually with a fine scale, a distinctive, acute clinical presentation of an eruption is known as guttate psoriasis. Guttate psoriasis is more common in people younger than 30 years of age. Secondary to group A beta-hemolytic streptococci, Streptococcus pyogenes for example, a history of upper respiratory infection often precedes the eruption by 2-3 weeks. While isolated bouts are known to occur, recurrent episodes may occur, particularly those which are the result of pharyngeal carriage of streptococci.

Pustular Psoriasis

Pustular psoriasis is primarily observed in adults. It is described by white pustules, which are blisters of noninfectious pus, surrounded by red skin. This pus is consisted of white blood cells. It is neither an infection, nor is it contagious.  Certain areas of the body are the place where it may be localized, the hands and feet for example. This type of psoriasis can also be generalized i.e. covering most of the body. Before the formation of pustules and scaling, pustular psoriasis tends to go in a cycle-reddening of the skin.
