The morphology of common warts depends on the inducing human papillomavirus (HPV) type. In order to assess the impact of the virus type on wart epidemiology we determined the virus type by PCR and recorded anamnestic data of 238 patients with common warts. Warts induced by the related HPV types 2, 27 and 57 predominated in the study population (n = 202). These warts mostly occurred as multiple verrucae vulgares, mosaic warts or endophytic warts. Patients aged between 10 and 30 years were most affected and they typically displayed a long disease history (mean duration of warts at the time of first clinical examination, 22 months). A different age distribution was observed in HPV 1-induced warts, most of which occurred in children 6-10 years of age. HPV 2-related warts responded only modestly to treatment, as they persisted in approximately 50% of all patients for more than 6 additional months. No sex preference was detected, but an association with atopic diseases was noted as 39.8% of patients with warts containing HPV 2-related viruses showed a history of atopic eczema, pollinosis or asthma as compared with 20.6% of the control population without a history of warts or with short-duration wart disease. Thus, our results indicate that the epidemiology, as well as morphology, of common warts is closely linked to the virus type.
