Intralesional bleomycin sulfate injection for the treatment of verruca plantaris.

Sixty-two patients were treated for single or multiple warts by intralesional injection of bleomycin sulfate (1.5 U/mL) and then were observed for 6 months. The dose varied according to the size of the lesion and ranged from 0.25 to 1.0 mL per injection per lesion, up to a maximum dose of 3 mL. The total cure rate was 87% after one or two injections. Twelve of the 62 patients required a second injection.
