Dinitrochlorobenzene treatment of condylomata acuminata.

Fifteen patients with treatment-resistant condylomata acuminata have been treated by application of Dinitrochlorobenzene (DNCB). The agent was applied weekly as a 0.5 or 1% solution in acetone for a period of 6 to 8 weeks. Patients were sensitised 15 days before the onset of treatment by applying a 2% DNCB solution on the right arm in a quantity of 0.15 ml. In one patient treatment had to be stopped because of local irritation and one discontinued treatment. In the other 13 patients all lesions cleared completely. Patients were followed up for a year and no recurrence has appeared as yet. DNCB seems to be useful agent for treatment-resistant condylomata acuminata and justifies further clinical trials.
