Pseudorheumatoid nodules in an adult

The finding of soft tissue lesions that present as rheumatoid nodules in a patient with no history or symptoms of rheumatoid arthritis or rheumatic fever sets the stage for a variety of differential diagnoses. One of the diagnoses that must be considered is the pseudorheumatoid nodule, which is rarely found in the adult. This article deals with one such case. A review of the literature is discussed along with a description of the remaining diagnoses from which it is distinguished. In this particular case, the patient presented lesions typifying those of rheumatoid nodules with the absence of any constitutional symptoms. Follow-up to date shows no signs of rheumatoid arthritis, although the literature does suggest the possibility that these lesions may be the precursor of the disease.
