To elucidate some of the recently arisen issues related to the bimodal disease pattern of vulvar intraepithelial lesions (VIN) and vulvar cancer, a series of 27 consecutive women with vulvar symptoms was analyzed for human papillomavirus (HPV) involvement by colposcopy, light microscopy and in situ hybridization (ISH) for HPV types 6, 11, 16, 18, 31, 33 and 42. Altogether, HPV DNA was discovered in 13/27 (48.1%) of the lesions by ISH; the rest were HPV DNA negative for the seven HPV types tested. HPV DNA was present in both of two exophytic lesions (HPV 6 in condyloma and HPV 16 in verrucous cancer). Of the flat lesions, 7/13 (53.8%) were HPV DNA positive. HPV 6 was confined to low grade lesions (HPV/non-VIN and VIN 1), whereas HPV 11 was found in a case of VIN 3 as well. Of the invasive carcinomas, three of four were HPV DNA positive (2 HPV 16 and 1 HPV 31). Dystrophic changes were detected in three of four invasive carcinomas and in all three HPV 16-positive lesions. Dystrophic changes were absent in 9 of 14 (64.3%) of HPV DNA-negative lesions. Fifty percent (7/14) of vulvar warty lesions (without concomitant VIN) were found in women younger than 60. Three of four invasive carcinomas occurred in women older than 60. This small series provided additional evidence of HPV involvement in the pathogenesis of VIN lesions, and the findings support the hypothesis of a multifactorial etiology in vulvar carcinogenesis in which HPV, dystrophic changes and chronic inflammatory disease play a synergistic role.
