Background
- Subtype of mature peripheral T-cell lymphoma
- Previously also known as angioimmunoblastic lymphadenopathy with dysproteinemia, immunoblastic lymphadenopathy, and lymphogranulomatosis X
- Accounts for 1 to 2% of non-Hodgkin lymphoma
- Derives from follicular T helper (TFH) cells
Clinical Manifestations
- Myriad and often non-specific, resulting in delayed diagnoses
- Usually advanced stage at diagnosis
- Most common symptoms are constitutional symptoms (fevers, night sweats, weight loss) and lymphadenopathy
- May have hepatosplenomegaly
- May have skin lesions which range from urticaria to nodules
- May get rash after antibiotics
- Often have elevated LDH, anemia, positive DAT, hypergammaglobulinemia (polyclonal)
- May have hypereosinophilia, occasionally have thrombocytopenia
- May have false-positive autoimmune tests, including rheumatoid factor and anti-smooth muscle antibodies
Prognosis
- 5-year survival about 30%
Further Reading
- Angioimmunoblastic T-cell lymphoma: the many-faced lymphoma. Blood. 2017;129(9):1095-1102. doi: 10.1182/blood-2016-09-692541
