What are the areas will be affected with lesions?

Psoriasis may affect any region in the skin in human body. In majority of cases, the disease will be started over the scalp (scalp psoriasis), behind the ears and then may be extended to other area of the body. In such cases, the problem might have been ignored at first by thinking that of dandruff and supposed to try many of antidandruff lotion. Some patients will develop psoriatic lesions only in flexural (flexural psoriasis) areas like arm pit, around genitals, under breasts, in between abdominal folds, fingers, toes, behind the ears etc. Psoriasis may affect palm and sole exclusively (palmar and plantar psoriasis) and nails alone (psoriatic nails). Plaque psoriasis is the most common form of psoriasis and affects 80 to 90% of people with psoriasis. Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery white scaly skin. Modest percentage of people may develop widespread inflammation and exfoliation (erythroderma). Sometimes lesions may be accompanied with pustular eruptions (pustular psoriasis).
