OBJECTIVE: To study the correlation of cervical condyloma and cancerous lesions with HPV infection.
METHODS: Cervical biopsies and histopathological examinations were performed on 179 cases which had abnormal cervical cytological smears. PCR was used to study the HPV-DNA of 128 cases and in situ hybridization (ISH) was used to study 10 cases.
RESULTS: 1. Morphologic observations. Most cervical condyloma cases were of the morphologically flat type (97.7%). Two koilocyte types were observed, the classical, or so called diagnostic koilocyte type (39.7%) and the atypical type (60.3%). Cervical condyloma often occurred together with cervical intraepithelial neoplasia (CIN, 42.5%). 2. PCR HPV DNA subtype analysis. Of the 58 cervical flat condyloma, 5 were PHV6/11 positive (8.6%) and 28 were HPV16/18 positive (48.3%). 86.1% of those with atypical koilocyte and 9.1% of those with diagnostic koilocyte had HPV16/18 infection. 66.7% of the lesions in which condyloma coexisted with CIN(2-3) had HPV16/18 infection.
CONCLUSIONS: Most cervical condyloma lesions were of the flat type. The appearance of atypical koilocyte is correlated to HPV16/18 infection, which in turn is correlated to the degree of CIN malignancy.
