Angio-immunoblastic lymphadenitis: remarks about two cases.

    Summary

    This study presents two cases of angioimmunoblastic lymphadenitis (AIL) in patients over 50. AIL may result from a prolonged hyperimmune response due to hypersensitivity to unknown factors.

    Area of Science:

    • Immunology
    • Pathology
    • Oncology

    Background:

    • Angioimmunoblastic lymphadenitis (AIL) is a rare extranodal non-Hodgkin lymphoma.
    • AIL typically presents in older adults with constitutional symptoms and lymphadenopathy.

    Observation:

    • Two patients over 50 years old presented with AIL symptoms, including lymphadenopathy, fever, pruritus, and hyperglobulinemia.
    • Histopathological examination of lymph nodes revealed a characteristic triad: diffuse lymphoid proliferation, arborizing small vessels, and paraamyloid-like material deposition.

    Findings:

    • The observed lymph node changes in both patients align with the diagnostic criteria for angioimmunoblastic lymphadenitis.
    • The clinical presentation and histological findings suggest a hyperimmune response potentially triggered by external factors.

    Implications:

    • These cases highlight the importance of recognizing the distinct histological features of AIL for accurate diagnosis.
    • Understanding the underlying hyperimmune response in AIL could lead to novel therapeutic strategies targeting hypersensitivity mechanisms.
