  • Title: [Immunohistochemical study on human papillomavirus infection of the vulva].
    Author: Wei ZM, Zhao YT.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 1993 Apr; 28(4):205-7, 252. PubMed ID: 8404301.
    Abstract:
    Two hundred and sixteen cases of human papillomavirus infection of the vulva from 1984 to 1991 in the Affiliated Hospital of Qingdao Medical College were reviewed, and were immunohistochemically studied by ABC method to detect HPV-Ag. The results showed that the demonstration of diagnostic koilocytes is very important in diagnosis of HPV infection in routine tissue slides examination. But in cases of atypical morphological changes; when diagnostic koilocytes were not formed in early stage, the demonstration of brown color granules in the nuclei of prickle cells is very diagnostic for positive HPV infection. In occasional cases, the diagnostic koilocytes do not demonstrate brown color granules in their nuclei. The explanation is that HPV-Ag was exhausted during metabolism. Besides, the cell membrane of basal cells are stained with brown color granules, while the morphological changes of upper layers of squamous epithelium have not appeared yet, therefore, there were no HPV-Ag positive reactive cells. It is probably showed that the HPV-Ag is primarily formed and appeared in the cell membrane of basal cells.
