[Treatment of common warts with topically applied DNCB (author's transl)]

Twenty-one patients suffering from multiple common warts were treated by topically-applied dinitrochlorobenzene (DNCB). After an average treatment period of 8.7 weeks, the warts had completely disappeared in twelve patients. Therapeutic failure must be admitted in five patients, whereby, sensitization to DNCB was not possible in two of these cases. Four patients did not complete the therapeutic regimen. Indications, advantages, disadvantages and side effects of this therapeutic method are discussed and an attempt is made to explain the underlying mechanism of this form of treatment.
