BACKGROUND: Human papilloma virus (HPV) is increasingly recognized as an important human carcinogen but its role in the aetiopathogenesis of basal cell carcinoma (BCC) in immunocompetent individuals is unclear.
OBJECTIVE: A prospective case-control study was designed to compare the prevalence of HPV in BCC and normal skin samples from immunocompetent subjects and to assess the influence of different clinical features on the risk of cutaneous HPV.
METHODS: A total of 142 samples from 70 BCC cases (superficial BCC 38 and nodular BCC 32) and 72 controls were analysed by a degenerated nested PCR technique. Clinical data were recorded and risk factors for HPV infection were assessed by multivariate analysis.
RESULTS: There were 31 HPV DNA-positive samples. HPV was detected more frequently in cases (25.7%) than in controls (18.1%) and in nodular (31.3%) than in superficial (21.1%) BCC lesions but differences were not statistically significant. Older age (OR 1.5; 95% CI: 1.02-1.09) and actinic keratosis (OR 2.62; 95% CI 1.15-5.96) were the only significant factors associated to the presence of HPV. Risk of HPV positivity was also higher in blond-haired subjects, fair/pale skin colour, history of sunburn, solar lentigines and seborrheic keratosis but the differences were not significant. Both in cases and controls, β -types were the most frequent.
CONCLUSIONS: HPV does not seem to play a fundamental role in the aetiopathogenesis of either nodular or superficial BCC. The presence of HPV appears to be more related to actinic damage and possibly to an alteration of the barrier function associated with ageing.
