[Treatment of common warts].

Spontaneous healing of warts should be followed up for at least for six months, preferably one or two years. Salicylic acid products, i.e. anti-wart drops, gel and salicylic acid plaster, are still the cornerstones of the treatment of warts. Approximately four out of five warts are healed up in 1 to 3 months. The therapeutic value of formic acid solution or trichloroacetic acid products is not established. Other options available for the doctor include cryotherapy with liquid nitrogen and in cases of difficult, isolated plantar warts, removal of the lesion with a punch and diathermy which may be applied to selected hand warts also.
