Palindromic rheumatism (PR) is an intermittent disease characterised by recurrent and self-resolving attacks of inflammation in the articular and peri-articular tissues. Attacks usually are monoarticular and last from a few hours to a few days. 1 During attacks, patients are asymptomatic. 1 Attacks mostly involve the knees, wrists, metacarpophalangeal joints and proximal interphalangeal (PIP) joints. 1 Finding autoantibodies associated with rheumatoid arthritis (RA) in a large percentage of patients with PR is an interesting feature of this disease. 2,3 In most reports, the frequency of positive rheumatoid factor (RF) and anticyclic citrullinated peptide (anti-CCP) in patients with PR is similar to RA. 2,3 Two recent studies reported two other autoantibodies, antimutated citrullinated vimentin (anti-MCV) in 70% and anticarbamylated protein/peptide antibodies (anti-CarP) in 24% of PR patients. 4,5 PR is an important disease despite the little attention paid to it. Firstly, PR is a relatively common disease. Pasero and Barbieri reported that the frequency of PR was 5% of RA. 6 Powel et al reported more prevalence of PR and concluded that for each of the
