Introduction: Rheumatoid arthritis (RA) is an autoimmune disease that manifests as a progressive mutilating arthritis with rare systemic involvement. The prevalence of its pleuropulmonary manifestations hardly exceeds 5% of cases. The reported ones include: pleurisy, interstitial fibrosis, effusion, rheumatoid nodules, and Caplan’s syndrome. The latter has been described in association with disease activity or as late complications.
Case Report: We present a patient with progressive and unilateral pleural effusion (PE) due to rheumatoid arthritis (RA) yet without overt systemic manifestations of disease which is exceedingly rare. Diagnosis was suspected by an exudative PE that had low glucose (compared to his serum) and pathognomonic cytology. Subsequently, it was confirmed by high anti-cyclic citrullinated peptide (anti-CCP) antibody. The effusion regressed significantly, 1 month later, after Prednisone and Rituximab therapy.
Conclusion: Rheumatoid arthritis should be considered in patients presenting with exudative PE that lacks history of trauma, and manifestations of infection, malignancy, and autoimmune diseases. High anti-CCP and cytological examination are useful in diagnosis.
