5-Fluorouracil in the treatment of common warts of the hands. A double-blind study.

A double-blind study was carried out to compare the action of 5-fluorouracil and 10% salicylic acid varnish with that of a 10% salicylic acid varnish on common warts. Fifty per cent of the lesions disappeared with the combined preparation and only 4% with the varnish containing salicylic acid alone. The presence of warts on the hands of 45.8% of the female workers of a fowl slaughterhouse is described.
