Abstract
We examined retrospectively a series of 65 Bouin's fixed, paraffin-embedded tissue specimens from 8 condylomatous lesions, 16 condylomas associated with cervical intraepithelial neoplasia (CIN), and 12 neoplasia without condylomatous signs, for histological characteristics, the detection of viral structural antigen, the presence and typing of HPV DNA by molecular in situ hybridization with biotinylated probes types 6, 11, 16 and 18 under stringent conditions (Tm - 12 degrees C). HPV DNA was present in 34/65 (52%) specimens. Detection of viral structural antigen was positive in only 14% (3/22) specimens. HPV DNA were identified in 9/9 (100%) condylomatous lesions (with HPV type 6, 11, 18). Three condylomas were coinfected with both HPV type 6 or 11 and type 18; viral antigen was found in two specimens. HPV DNA were detected in 18/31 (58%) low grade and advanced CIN associated with condylomatous changes (type 6 = 5 specimens, type 11 = 3 specimens, type 16 = 4 specimens, type 18 = 6 specimens). Four of these cases were coinfected with both HPV type 6/11 and HPV type 16/18. Viral antigen was negative in all specimens. HPV DNA were detected in 7/25 (28%) advanced intra-cervical neoplasia (CIN III) without anatomopathological condylomatous changes (type 6 = 1 specimen, type 16 = 3 specimens, type 18 = 3 specimens). One of these specimens contained both HPV types 6 and 18. Viral antigen was found in one case. Our data confirm the association of HPV types 6 and 11 with condyloma and low grade neoplasia; HPV types 16 and 18 were associated with advanced cervical neoplasia.
