244 cervical tissue specimens with different diagnoses were stained by peroxidase-anti-peroxidase technique (PAP) for assay of the human papillomavirus (HPV) genus-specific antigen, the first of its kind performed in China. HPV antigen was detected in 41.93% of simple condyloma group, in 35.29% of dysplasia with condyloma and in 27.27% of carcinoma with condyloma. There was no positive in the control, dysplasia or carcinoma groups. The antigen positive nuclei were found in the koilocytes or parakeratosis cells in the upper layers of the epithelium. The severer the condyloma, the higher the positive rate of antigen. In the severe condyloma group, the positive rate was as high as 64.71%. The koilocytes were observed in every HPV antigen positive section. In view of the coexistence and continuous transformation of condyloma, dysplasia and carcinoma in pathomorphology, these results provide an important evidence to the further studies on the relation between HPV infection and carcinogenesis of cancer of uterine cervix.
