Abstract
Introduction
Rheumatoid nodules are one of the most common extra-articular manifestations in rheumatoid arthritis (RA) being extremely uncommon in the ocular and periocular area. To the authors’ knowledge, this is the second case of an orbital rheumatoid nodule.
Case description
A 44-year-old woman with RA presented with a painful hard mass in the inferolateral right orbital rim causing mild lower lid retraction, ptosis and exophthalmos. Magnetic Resonance Imaging showed a extraconal mass involving the lower eyelid and fat tissue of the infratemporal fossa. An incisional biopsy demonstrated an orbital rheumatoid nodule.
Conclusions
Rheumatoid nodule's should be considered as a differential diagnosis for an orbital tumour found in patients with RA.
