Myc/Bcl2 Double-Hit Lymphoma In A Patient With Rheumatoid Arthritis Associated With Methotrexate Treatment
INTERNAL MEDICINE(2016)
摘要
Several reports have suggested an increased risk of malignant lymphoma in patients with rheumatoid arthritis treated with methotrexate (MTX). We herein describe the case of a 71-year-old woman with rheumatoid arthritis who developed MYC/BCL2 double-hit lymphoma associated with MTX therapy. She developed a fever and lymphadenopathies over a 2-week period and had elevated levels of soluble IL-2 receptor. Inguinal lymph node and bone marrow biopsies showed diffuse large B cell lymphoma. Fluorescent in situ hybridization revealed MYC and BCL2 gene rearrangements in her lymphoma cells. Accordingly, a diagnosis of MYC/BCL2 double-hit lymphoma was made. This is the first reported case of a double-hit lymphoma associated with MTX therapy.
