Psoriasis may classically have widespread skin signs, it sometimes presents as a foot problem. Along with feet, it can occur at many other sites. It is a very common disorder, and has been estimated to affect 2 per cent of the population. The exact cause of psoriasis is unknown but it is thought that genetic factors play an important role. The known triggers for psoriasis include bacterial infections, trauma to the skin, severe mental stress, and certain drugs, e.g. oral lithium salts used in psychiatry and chloroquine.
Psoriasis affects the sexes equally. It may appear for the first time at any age, but is very rare before the age of 5, and uncommon before 15 years of age. The clinical features of psoriasis vary depending on the site of involvement. The common sites of involvement are the extensor surfaces (outside of palms, soles, knees and elbows). The typical lesion is a well-demarcated red, raised patch with silvery white scales
The nails are also affected in approximately 50 per cent of patients with psoriasis. The most common feature is small uniform pits in the nails. Other features include breaking of nails, thick and dystrophic nails.
Five per cent of patients with psoriasis develop arthritis. It is similar in its distribution to rheumatoid arthritis (RA) except joints involved are different than one in RA. Psoriatic involvement of the joints may be self-limiting but in severe cases permanent damage and deformity of joints can occur.
If psoriasis is active, then whatever treatment is given the condition is likely to return when treatment is discontinued, whereas if the disorder is not active, a long subsidence may be obtained with the same treatment.
