Rheumatoid nodule presenting as a buccal submucosal nodule: A rare presentation of a common disease.

BACKGROUND

Rheumatoid nodules are a common manifestation of rheumatoid arthritis but buccal rheumatoid nodules are extremely rare. The purpose of this study was to report a rare case of a rheumatoid buccal nodule and a review of the literature.

METHODS AND

RESULTS

This case is about a 79-year-old woman with rheumatoid arthritis who was taking methotrexate and hydroxychloroquine, presenting with an enlarging left buccal submucosal mass. An incisional biopsy showed features consistent with that of a rheumatoid nodule. The mass was managed expectantly and the patient was taken off methotrexate with a marked reduction in the size of the nodule.

CONCLUSION

Submucosal rheumatoid nodules of the oral cavity are an extremely rare manifestation of rheumatoid arthritis but should be considered in the differential diagnosis in patients with a history of rheumatoid arthritis presenting with submucosal masses. © 2016 Wiley Periodicals, Head Neck 39: E12-E14, 2017.
