Abstract:
Epstein-Barr virus (EBV) associated lymphoproliferative disorders includes a diverse group of diagnoses, encompassing both B-cell and T-cell lineages. With EBV mucocutaneous ulcers becoming a World health Organization diagnosis in 2018, introduction of the disease entity will be beneficial to the practicing otolaryngologist. We are reporting a case of a 69-year-old male with history of rheumatoid arthritis on methotrexate, recently undergoing dental extractions, who then developed multiple oral ulcerations and bony erosions of his palate and alveolar ridge. Associated symptoms included a large 3.0 cm neck mass, splenomegaly, and pulmonary nodules. Histopathology showed EBV+ lymphomatoid granulomatosis. Upon removal of immunosuppressive agent, patient's symptoms improved with resolution of oral lesions, as well as systemic symptoms.
