  • Title: In situ hybridization analysis of human papillomavirus DNA in oral mucosal lesions.
    Author: Zeuss MS, Miller CS, White DK.
    Journal: Oral Surg Oral Med Oral Pathol; 1991 Jun; 71(6):714-20. PubMed ID: 1648192.
    Abstract:
    Commercial biotinylated DNA probes specific for human papillomavirus (HPV) types 6 and 11; 16 and 18; and 31, 33, and 35 were used for in situ hybridization analysis of 105 oral mucosal specimens from 5 cases of verruca vulgaris, 15 cases of condyloma acuminatum, 30 cases of squamous papilloma, 20 cases of hyperkeratosis/acanthosis, 15 cases of epithelial dysplasia, 5 cases of carcinoma in situ, and 15 cases of squamous cell carcinoma. Positive hybridization signals were found in 26 specimens (24.8%). Only HPV-6/11 was detected. HPV DNA occurred significantly more often (p less than 0.005, chi-square analysis) in condyloma acuminatum (100%) and verruca vulgaris (100%) than squamous papilloma (13.3%), hyperkeratotic/acanthotic lesions (10%), and malignant and premalignant lesions (0%). The tongue (19.1%) and labial epithelium (17.1%) were infected most frequently. Nuclear reaction products indicating HPV infection were associated primarily with koilocytes. These results demonstrate the usefulness of commercial biotinylated probes for HPV DNA analysis in routine paraffin-embedded lesion specimens. They confirm HPV involvement in benign lesions of the oral mucosa but fail to associate HPV infection with oral cancer and precancer.
