Angioimmunoblastic Lymphadenopathy with Dysproteinemia
Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) may represent a spectrum of diseases ranging from reactive (and a reversible) process to frank malignant lymphoma. The consensus is that it represents a subtype of peripheral T-cell lymphoma. The clinical presentation includes high-grade fever, rash, anemia, and polyclonal hypergammaglobulinemia. The nodal architecture is effaced by a polymorphic cellular infiltrate and a marked vascular proliferation (seen here).
