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

- May have hepatosplenomegaly
