Gingival ulcer in a patient with psoriatic arthritis.

This document is a reference list and author contributions for a case report titled "Gingival ulcer in a patient with psoriatic arthritis." The case involved a 70-year-old woman with psoriatic arthritis who developed a symptomatic gingival ulcer while being treated with methotrexate and risedronate sodium. An incisional biopsy was performed, and the diagnosis was determined to be Epstein-Barr virus (EBV)-positive mucocutaneous ulcer (EBVMCU). The ulcer resolved after 30 days of follow-up, and tooth #27 was extracted due to extreme mobility after the biopsy. The authors have no conflicts of interest to disclose and the patient provided written informed consent for publication. [Extracted from the article]
