He had extensive work-up over two years including an infectious diseases panel, autoimmune studies, and Rheumatology and Hematology evaluations. The patient was initially diagnosed with Adult Still’s disease and underwent an out-patient right nodal fine-needle aspiration that was indeterminate. After continued failure of treatment for Adult Still’s disease, the patient had surgical resection of a right axillary lymph node that yielded the diagnosis of diffuse large B-cell lymphoma. Further work-up revealed Epstein-Barr virus positivity, the possible trigger behind his mutation for diffuse large B-cell lymphoma and its uncommon presentation. The patient met criteria for central nervous system prophylaxis and received multiple administrations throughout his therapy. He ultimately expired following recurrence of his disease at its initial site but without central nervous system involvement. We report an uncommon presentation of a patient with diffuse large B-cell lymphoma. This lymphoma can have numerous, vague presentations requiring a broad differential diagnosis and may lead to multiple evaluations prior to an ultimate diagnosis. We will also discuss the need for central nervous system prophylaxis, how this patient is qualified for prophylaxis, and how central nervous system prophylaxis benefits, harms, or does not affect patients with diffuse large B-cell lymphoma.展开更多
