Immune reconstitution inflammatory syndrome mimics a relapse of AIDS-related Burkitt lymphoma

Abstract

Immune reconstitution inflammatory syndrome (IRIS) is associated with clinical manifestations that can overlap with the patients with acquired immunodeficiency disease (AIDS)-related non-Hodgkin's lymphoma. We herein report a case of AIDS-related Burkitt lymphoma which was successfully treated with dose-adjusted etoposide, doxorubicin, cyclophosphamide, vincristine, and prednisone (EPOCH). However, the patient developed a lymphoma-like clinical presentation shortly after the conclusion of chemotherapy. The patient's symptoms were identical to the initial symptoms characteristic of lymphoma; however, the laboratory data revealed no evidence of a relapse of Burkitt lymphoma. A bone marrow examination showed T-cell clonality, even though there were no signs of any progression of the lymphoma. The patient was diagnosed with IRIS, and the clinical manifestations rapidly improved following treatment. © 2013 The Japanese Society of Internal Medicine.
