Rheumatoid nodule mimicking an olecranon bursitis as the primary manifestation of rheumatoid arthritis

Abstract

Olecranon bursitis is a relatively common condition, being most of the cases idiopathic. Less commonly it is caused by infection, by a systemic inflammatory process or by a crystal-deposition disease such as gout or pseudogout. We present a case that was referred as olecranon bursitis, in which the diagnose of rheumatoid nodule was stablished after histological study of the resected tissue.
