In situ hybridization (ISH) and polymerase chain reaction (PCR) for several common HPV types were performed on 41 cases of vulvar dystrophy, 19 of which were associated with previous or simultaneous invasive squamous cell carcinoma of the vulva. Three of the 19 cases (16%) of dystrophy associated with cancer were found to contain HPV-16/18 by PCR. In contrast, 12 of the 22 cases (55%) of dystrophy not associated with carcinoma contained HPV-16/18 by PCR (P < 0.01). A control group of 10 vulvar specimens without dystrophy or carcinoma was negative for all HPV types tested. ISH was negative for all HPV types in all 41 cases. The data confirm the association between vulvar carcinoma and hypertrophic/mixed dystrophy, and provide evidence for an association between HPV-16/18 and some cases of vulvar dystrophy. Cases of vulvar dystrophy not associated with HPV-16/18 may be at increased risk for the development of vulvar carcinoma.
