Epidermodysplasia verruciformis. Skin carcinoma containing human papillomavirus type 5 DNA sequences and primary hepatocellular carcinoma associated with chronic hepatitis B virus infection in a patient.

In a case of epidermodysplasia verruciformis with impaired cell-mediated immunity and multiple skin cancers human papillomavirus type 5 (HPV5) DNA sequences were demonstrated in a cutaneous squamous cell carcinoma. HPV5 and HPV8 were detected in the benign disseminated skin lesions together with three newly characterized HPVs: HPV17, HPV19 and HPV24. A chronic infection with hepatitis B virus resulting in macronodular cirrhosis associated with a primary hepatocellular carcinoma was also acquired by this patient.

[Presence of papillomavirus genomes and amplification of the c-myc and C-Ha-ras oncogenes in invasive cancers of the uterine cervix].

Invasive squamous cell carcinomas of the uterine cervix from 12 untreated patients were examined for the presence of human papillomavirus (HPV) genomes and for the state of the oncogenes c-myc and c-Ha-ras. Blot hybridization experiments have demonstrated the presence of the genome of HPV type 16 (HPV 16) in six tumors and that of the genomes of HPV types weakly related to HPV 16 or HPV 18 in five others. In the nine tumors corresponding to advanced stages of the disease (stages 3 and 4) there was a 3-30 fold amplification of c-myc and/or c-Ha-ras.

Detection of human papillomavirus type 5 DNA in skin cancers of an immunosuppressed renal allograft recipient.

A renal allograft recipient with an epidermodysplasia-verruciformis-like syndrome was found to have human papillomavirus type 5 (HPV-5) in his benign warty lesions and HPV-5 DNA in two of his skin cancers. This finding points to a role for HPV-5 in skin oncogenesis in renal allograft recipients.
