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%
