Angioimmunoblastic t-cell lymphoma with polyarthritis resembling rheumatoid arthritis

Abstract

Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL). AITL typically presents with lymphadenopathy, fever, rash, hepatosplenomegaly, and rarely polyarthritis. We report the case of a 50-year-old female who presented with lymphadenopathy, rash, and symmetric polyarthritis. She was later diagnosed with AITL and was treated with chemotherapy with resolution of arthritis. AITL should be suspected in paitents presenting with rheumatoid-like arthritis and diffuse lymphadenopathy.
