 AB    Fifteen biopsy specimens of oral AIDS-associated Kaposi's sarcoma (KS),
       19 biopsy specimens of uninvolved oral mucosa of HIV-seropositive
       patients (HIV+) and 22 biopsy specimens of oral mucosa of
       HIV-seronegative persons (HIV-) were analysed for the distribution of
       CD4+ and CD8+ lymphocytes and HLA-DR+ cells. The results were
       statistically evaluated. According to their clinical appearance KS were
       classified as flat lesions (n = 10) or exophytic tumours (n = 5). KS
       lesions of both clinical groups as well as uninvolved mucosa of HIV+
       patients revealed infiltration with CD4+ cells. In flat, patch-like KS
       there was a marked increase of CD8+ cells compared to HIV- mucosa, while
       their numbers decreased in later tumour stages. In both, flat and
       exophytic KS the number of HLA-DR+ cells was significantly higher than
       in uninvolved mucosa of HIV+ and HIV- persons. These findings may
       reflect the local influence of KS growth factors on the inflammatory
       reaction in the setting of systemic immunosuppression.
