Abstract
Background and objectives:
Non-genital warts are benign cutaneous growths caused by infection with the human papillomavirus. Although warts can resolve spontaneously, patients might seek treatment due to discomfort or social ostracism. This review summarises high-quality studies investigating the efficacy of chemical and physical destructive wart therapies.
Method:
We performed a literature review (up to June 2021) of published articles for wart management from MEDLINE and Embase databases. We considered systematic reviews, randomised controlled trials (RCTs), cohort studies and case series. We included studies that investigated chemical or physical destructive therapies.
Results:
Fifteen therapies were evaluated and included salicylic acid, cryotherapy, silver nitrate, phenol, cantharidin, glycolic acid, pyruvic acid, citric acid, formic acid, trichloroacetic acid, monochloroacetic acid, zinc, laser, surgery and electrocautery. Very few treatment options have been studied through RCTs.
Discussion:
To attenuate transmission, hygienic practices need to be adopted in conjunction with any treatment. Important considerations when treating patients with warts include the location of the wart, the evidence supporting the proposed treatment and potential adverse effects of treatment.
