When monoarthritis is caused by "pseudogout" (calcium pyrophosphate deposition disease, CPPD), the inflammation usually lasts days to weeks, and involves the knees in half of all attacks. Like gout, attacks can occur spontaneously or with physical trauma or metabolic stress. Patients may feel well in between pseudogout attacks, and 5% present with pseudo-rheumatoid symptoms.

Occurs in 5-10% of patients who have psoriasis.Classic presentation involves the DIP(distal inerphalangeal joints).Morning stiffness is present.Deformity of involved joints,dactylitis and nail involvement are common.Well demarcated red plaques with silvery scaling - the classic lesions of psoriasis are seen on the dorsum of the hand.

The second most common clinical finding of this disease is joint pain with or without arthritis, after chondritis.

All synovial joints may be affected.

At presentation, around 33% of people have joint symptoms that involve Polyarthralgia and/or polyarthritis or oligoarthritis that affects various parts of the body and often appears to be episodic, asymmetric, migratory and non-deforming. The most common sites of involvement are the metacarpophalangeal joints, proximal interphalangeal joints and knees. After which is followed by the ankles, wrists, metatarsophalangeal joints and the elbows. Any involvement of the axial skeleton is considered to be very rare. Tests for rheumatoid factor are negative in affected persons with RP, unless there is a co-morbidity with RA.

Less often it has been reported that persons may experience arthralgia, monoarthritis, or chronic polyarthritis that mimics rheumatoid arthritis, leading to a difficult diagnosis for this disease. The appearance of erosions and destruction, however, is exceedingly rare and this may point instead to rheumatoid arthritis as a cause.

Diseases and inflammation of tendons have been reported in small numbers of people with RP. During the course of the disease, around 80% of people develop joint symptoms.

Relapsing polychondritis may affect many different organ systems of the body. At first, some people with the disease may have only nonspecific symptoms such as fever, weight loss, and malaise.
