[入口詞] AIDS-Related Lymphomas
[主題詞] Lymphoma,AIDS-Related
[英文釋義] B-cell lymphoid tumors that occur in association with AIDS. Patients often present with an advanced stage of disease and highly malignant subtypes including Burkitt lymphoma,immunoblastic large-cell lymphoma,small non-cleaved-cell lymphoma and diffuse large-cell lymphoma. The tumors are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in AIDS is a complex result of EBV infection,HIV antigenic stimulation,and T-cell-dependent HIV activation.
