Angioimmunoblastic T-cell lymphoma (AIL-TCL) following macrolide administration.
Angioimmunoblastic Lymphadenopathy with Dysproteinemia (AILD) is a rare benign reactive process which often follows exposure to certain drugs such as penicillin. Treatment with corticosteroids usually reverses the process, however there have been reports of 18% of cases evolving into non-Hodgkins lymphoma. In our case report, we present a relatively healthy woman with history of various drug hypersensitivities who developed AILD and resultant lymphoma after treatment with azithromycin. A review of the literature has failed to find reports of AILD following macrolide exposure. Clonality, not present in other forms of hyperplasia, is present in AILD and immunosuppression may account for this difference. It is difficult to say whether the drugs are simply coincidently associated or actually cause, maintain, or exacerbate clonality in AILD and facilitate malignant transformation.
