Brief summary
The principal objective of the study is the evaluation of the role of Human Papilloma Virus (HPV) in plantar warts (prevalence, genotype), resistant or not, treated or not, cured or not. This epidemiological study is an ancillary study of the prospective, randomized controlled, clinical study VRAIE (sponsor: APHP) comparing 5 usual strategies in the management of plantar warts.

Inclusion criteria
* Male or female patient aged 18 years or more. * Clinical evaluation * Number of warts lower than 10 on the 2 feet and total diameter of warts lower than 10 cm, whether previously treated or not * In treated patients, all potentially active treatment on warts since at least one month should be stopped. * Effective contraception for women of childbearing age * Immunocompetent patients * Patient with one or more warts on soles and board feet. * MYRMECIE : rounded warts, deep, covered with a stratum corneum more or less thick; after stripping, appear black points, very specific; often painful to pressure. They are lonely, single or not. They could regroup galley thick. The stripping can them to individualize. * Mosaic : plate small warts, superficial, often sitting on the heel or Forefoot. Little painful, they are often ignored by the patients when they appear * Patient affiliated to the French social security.viral
