Spontaneous regression of HIV associated T-cell non-Hodgkin's lymphoma with highly active antiretroviral therapy.
A subcutaneous, T-phenotypic anaplastic large cell lymphoma (CD30/Ki1-positive, EBV positive) was diagnosed in a HIV-infected bisexual man. Without chemotherapy the patient had a sustained long-term remission of this tumor (more than three years) after the initiation of highly active antiretroviral therapy. By PCR analysis of T-cell receptor beta gene rearrangements the tumor was found to be oligoclonal. Improvement of cellular immune function by antiretroviral therapy is the only recognizable factor which may have led to tumor remission. This hypothesis is supported by parallels to EBV associated polyclonal lymphoproliferation in allogeneic transplantat recipients where regression of lymphoma can be induced by reducing immunosuppressive therapy.
