Treatment for simple plantar verrucae: monochloroacetic acid and 10% formaldehyde versus 10% formaldehyde alone

Verrucae are small, benign, highly vascular epithelial neoplasms that occur singly or in a multiple presentation. Plantar verrucae are usually caused by infection with human papillomavirus types 1, 2, and 4. A clinical trial was conducted to assess the safety and efficacy of monochloroacetic acid and 10% formaldehyde versus 10% formaldehyde alone in the treatment of simple plantar verrucae. Of 57 patients enrolled in the study, 26 were in the monochloroacetic acid and 10% formaldehyde group and 31 were in the 10% formaldehyde alone group. The overall cure rate for this population was 61.4%. There was no statistically significant difference in the cure rate between treatment groups.
