We report the case of a 14-year-old Japanese boy with peripheral T-cell malignant lymphoma, showing progression from immunoblastic lymphadenopathy (IBL) to overt malignant lymphoma. He suffered recurrent fever, generalized lymphadenopathy, hepatosplenomegaly and maculopapular exanthema. Leukocytosis with eosinophilia and polyclonal hypergammaglobulinemia were observed during the aggressive course of the disease. In the early phase, human immunoglobulin and steroids improved the symptoms but did not induce complete remission, and the patient died one year after the onset of the illness. Four biopsies of lymph nodes revealed progression from IBL to CD4 positive T-cell lymphoma through IBL-like T-cell lymphoma. Though IBL-like T-cell lymphoma is defined as IBL with neoplastic features and overt T-cell malignant lymphoma progressed from IBL-like T-cell lymphoma is excluded from the definition, it may be preferable that such malignant lymphoma as our case should also be included in IBL-like T-cell lymphoma.
