What are the different types of psoriasis?
Type of psoriasis
Psoriasis appears in a variety of forms of psoriasis with distinct characteristics. Typically, an individual has only one type of psoriasis at a time. Generally, one type of psoriasis will clear and another form of psoriasis will appear in response to a trigger.
There are several different types of psoriasis, including
Plaque Psoriasis – (psoriasis vulgaris)
Plaque psoriasis (psoriasis vulgaris) is the most prevalent form of the disease. About 80 percent of those who have psoriasis have this type. It is characterized by raised, inflamed, red lesions covered by a silvery white scale. It is typically found on the elbows, knees, scalp and lower back.
Guttate [GUH-tate] psoriasis is a form of psoriasis that often starts in childhood or young adulthood. The word guttate is from the Latin word meaning “drop.” This form of psoriasis appears as small, red, individual spots on the skin. Guttate lesions usually appear on the trunk and limbs. These spots are not usually as thick as plaque lesions.
Guttate psoriasis often comes on quite suddenly. A variety of conditions can bring on an attack of guttate psoriasis, including upper respiratory infections, streptococcal throat infections (strep throat), tonsillitis, stress, injury to the skin and the administration of certain drugs including antimalarials and beta-blockers.
Inverse psoriasis is found in the armpits, groin, under the breasts, and in other skin folds around the genitals and the buttocks. This type ofpsoriasis appears as bright-red lesions that are smooth and shiny. Inverse psoriasis is subject to irritation from rubbing and sweating because of its location in skin folds and tender areas. It can be more troublesome in overweight people and those with deep skin folds.
Postular – (psoriasis vulgaris)
Primarily seen in adults, pustular psoriasis is characterized by white blisters of noninfectious pus (consisting of white blood cells) surrounded by red skin. There are three types of pustular psoriasis.
Pustular psoriasis may be localized to certain areas of the body, such as the hands and feet, or covering most of the b
It begins with the reddening of the skin followed by formation of pustules and scaling.
Pustular psoriasis may be triggered by internal medications, irritating topical agents, overexposure to UV light, pregnancy, systemic steroids, infections, stress and sudden withdrawal of systemic medications or potent topical steroids.
Erythrodermic [eh-REETH-ro-der-mik] psoriasis is a particularly inflammatory form of psoriasis that affects most of the body surface. It may occur in association with von Zumbusch pustular psoriasis. It is characterized by periodic, widespread, fiery redness of the skin and the shedding of scales in sheets, rather than smaller flakes. The reddening and shedding of the skin are often accompanied by severe itching and pain, heart rate increase, and fluctuating body temperature.
People experiencing the symptoms of erythrodermic psoriasis flare should go see a doctor immediately.
Erythrodermic psoriasis causes protein and fluid loss that can lead to severe illness. The condition may also bring on infection, pneumonia and congestive heart failure. People with severe cases of this condition often require hospitalization.
Known triggers of erythrodermic psoriasis include the abrupt withdrawal of a systemic psoriasis treatment including cortisone; allergic reaction to a drug resulting in the Koebner response; severe sunburns; infection; and medications such as lithium, anti-malarial drugs; and strong coal tar products.
Psoriatic nail dystrophy mainly occurs in patients whom also suffer from psoriasis of the skin. Less than 5% of patients have solely psoriasis of the nails. It is commonly (53-86%) seen in patients with psoriatic arthritis especially when the arthritis affects the fingers and toes
The nail unit is made up of several parts; nail plate, nail bed, hyponychium, nail matrix, nail folds, cuticle, anchoring portion of the nail bed, and distal phalangeal bones. Signs of nail psoriasis vary according to the part of the nail affected and the nature of the deformity.
Psoriatic Arthritis Types
Psoriatic Arthritis TypesIf you show symptoms of PsA, your doctor will want to know which parts of the body are affected and the severity of your symptoms. This information helps identify which of the 5 types of PsA you may have.
Affects the same joints on both sides of the body, for instance, the right and left knees, right and left wrists, etc. Can resemble rheumatoid arthritis (RA).
Can occur in any joint, but not necessarily the same joints on both sides of the body. Fingers and toes can become enlarged and “sausage-like.”
Distal Interphalangeal Predominant (DIP)
Involves the joints of the fingers and toes closest to the nails. Changes in the nail are common. Is similar to, and sometimes confused with, osteoarthritis.
Refers to inflammation of the spinal column. Only about 5% of people with PsA have spondylitis as their main symptom. But a larger number of people with PsA will have similar symptoms—stiffness in the neck, lower back, pelvic area, or spinal vertebrae.
A severe, deforming, and destructive type of PsA that usually affects the small joints of the hands and feet. Can also cause neck and lower-back pain. Fewer than 5% of PsA patients have this type.
