title: [Initial clinicopathological manifestations of malignant lymphoproliferative processes in patients with human immunodeficiency virus seropositivity. Study of 40 cases].
abstract: We analyzed the series of 40 malignant lymphoproliferative diseases (MLD) in HIV positive patients, diagnosed between 1986 and 1993 in a University Hospital in Spain. Median age was 32 years. 52% of the patients belonged to the intravenous drug users risk group, and 30% were homosexual. 26 patients were diagnosed of a non-Hodgkin's lymphoma (NHL), 8 of Hodgkin's disease (HD) and 6 of a primary central nervous system lymphoma (PCL). The 6 patients with a PCL (median CD4 of 20 cells/mm3, 80% antecedent AIDS criteria) and 13 NHL with histology of immunoblastic, large cell, plasmablastic, and high grade lymphoma non-otherwise specified (median CD4 of 291, 58% with AIDS criteria) tended to appear in patients with a deteriorated clinical and immunological status due to the underlying HIV infection. However, the 14 small non-cleaved cell NHLs appeared in patients without a previous AIDS-defining condition (93% of the cases, p = 0.065 compared with other NHL histologies). Finally, 8 patients with HD had a low CD4 cell count (median 103 cells/mm3, p = 0.049 compared with median CD4 in NHL patients) without other previous AIDS criteria. In conclusion, The presenting characteristics of HIV positive patients with MLD allows to define four subgroups of patients with a high clinicopathological correlation.
