title: An immunohistological study of condylomata acuminata.
abstract: Using an indirect immunoperoxidase method and a panel of monoclonal antibodies, anogenital warts removed from 86 individuals (28 heterosexual men, 47 homosexual men and 11 women) were studied. A constant feature was the presence of a stromal infiltrate of lymphocytes, in which CD4+ and CD8+ cells appeared in a ratio of about 5:1. Cells expressing interleukin-2 receptors were found in the stroma, amounting to 10% of the CD3+ cells. Leu 6+ epidermal dendritic cells (Langerhans' cells) were present in each wart; their density and morphology were similar to that in adjacent, apparently normal, skin. The mean number of Langerhans' cells that expressed HLA-DQ was lower than that of HLA-DR + cells. In 40 warts, HLA-DR was expressed on the surface of keratinocytes. Leu 7+ and Leu 11b+ cells were found in the epidermis of 17 and five warts, respectively. B-cells were noted in only five warts. These results are discussed in relation to persistence of wart virus infection.
