• Plaque (discoid) psoriases:
Plaque psoriasis is the most common type affecting approximately 90% of psoriasis sufferers. The skin develops clearly defined patches of pink or red skin called plaques, which are covered with dry, crusty, silvery scales, which flake off.
• Guttate psoriasis:
This type of psoriasis usually presents in children and adolescents and can be the first sign of a 2 susceptibility to the condition. In a flare-up numerous small round red spots appear on the body, limbs and scalp.
• Flexural psoriasis:
Flexural psoriasis usually occurs in the folds of the body. The patches are inflamed and red, but do
not scale. This type of psoriasis tends to occur more often in older people, particularly older
women.
• Nail psoriasis:
Nail psoriasis is more common in people over 40 and is strongly linked with the development of psoriatic arthritis. Nails become ridged and they may lift away from the finger.
• Localized pustular psoriasis:
This type is more common in adults than in children and presents as pus-filled spots on the palms and soles. The affected areas are painful and might resist therapy.
• Erythrodermic psoriasis:
This is a rare condition, but could be life threatening, since large areas of the skin become inflamed and scaly and patients could loose their ability to control their body temperature and suffer from nutrient and fluid loss.
• Psoriatic arthritis:
Approximately 6% of people with psoriasis suffer from psoriatic arthritis (stiff painful and inflamed joints). The arthritis differs from other other forms of arthritis in the pattern of joints that are affected. With psoriatic arthritis an entire finger or toe becomes swollen and inflamed, rather than an individual joint. Common sites are the hands, feet, spine and neck.
