Psoriatic arthritis is an inflammatory arthritis that disturbs the smooth functioning of joints in the body. At present around 5-7% people suffering from the chronic skin condition psoriasis have developed this chronic syndrome. This is the arthritis condition which is referred as seronegative spondyloarthropathy and occurs usually in patients with tissue type HLA-B27. Psoriatic arthritis can similarly be traded like the rheumatoid arthritis. At present around 80% of patients having psoriatic arthritis have developed psoriatic nail wound by pitting of the nails.
Some people in extreme conditions even get loss of nails. Psoriatic arthritis can attack the body at ant age. Usually on an average it appears at about 10 years after the first mark of psoriasis is traced. In majority of cases Psoriatic arthritis happens between the ages of 30 and 50, but it can also affect children o any age. The disease affects equally both men and women. In very rare cases the symptoms of psoriatic arthritis may occur before any skin involvement.

The radiology gives the appearance of "fluffy, new" bone. Psoriatic arthritis is of different types but there are five main types which are discussed as below:
Symmetric: This category of Psoriatic arthritis in about 50% of cases affects the joints on both sides of the body at the same time. This type is almost similar to Rheumatoid arthritis and is disabling in around 50% of people having the syndrome.
Asymmetric: This type of Psoriatic arthritis is generally mild and affects around
35% of cases. Asymmetric does not develop in the same joints on both sides of the body. This joint pain usually only involves less than 3 joints.
Spondylitis: In Spondylitis the patient develops stiffness in the spine or neck. It also affects the hands and feet similarly as in symmetric arthritis.
Arthritis mutilans: It occurs in less than 5% of patients and is a severe form of Psoriatic arthritis. It is also considered as deforming and destructive arthritis. This syndromic condition can improve over months or years causing severe joint damage.
