Research output: Contribution to journalArticlepeer-review


Common skin warts frequently appear on the fingers of children, a patient population in whom finger-sucking is a prevalent habit. Despite overlap between these two pediatric conditions, there are no well-reported specific precautions against the use of topical blistering wart treatments, such as trichloroacetic acid and cantharidin, in finger-sucking children with warts. We report the case of oral ulcers in a pediatric patient secondary to thumb-sucking after receiving treatment for multiple finger warts with combination cryotherapy, trichloroacetic acid, and cantharidin.
