[Angio-immunoblastic lymphadenopathy (author's transl)]

Area of Science:

• Immunology
• Oncology
• Pathology

Background:

• Angio-immunoblastic lymphadenopathy (AILD) is an aggressive non-Hodgkin lymphoma.
• It is characterized by systemic symptoms and lymphadenopathy.

Observation:

• A case of AILD involving the tonsils is presented.
• The patient exhibited fever, pruritus, rash, generalized lymphadenopathy, and hepatosplenomegaly.
• Histological examination revealed characteristic features including arborizing vessels and immunoblast proliferation.

Findings:

• Laboratory results showed polyclonal hyperglobulinemia and hemolytic anemia.
• The histological triad of vascular proliferation, immunoblasts, and interstitial material confirmed the diagnosis.
• Treatment involved corticosteroids and supportive care.

Implications:

• AILD generally has a poor prognosis with a median survival of 13 months.
• The etiology of AILD remains unknown, necessitating further research.
• Understanding these findings aids in diagnosis and management of AILD.
