Use of trichloroacetic acid for management of oral lesions caused by human papillomavirus.

The human papillomavirus (HPV) has an affinity for squamous cells of stratified keratinized epithelium, thus affecting the lower genital, nasal, and oral tracts. In the oral cavity, HPV is associated with pathoses such as the verruca vulgaris (common wart), squamous cell papilloma, condyloma acuminatum (venereal wart), and focal epithelial hyperplasia (Heck disease). Among the treatments available for these lesions are cryotherapy, electrosurgery, surgical removal, laser therapy, and trichloroacetic acid (TCA). The objective of this research was to determine the behavior of HPV-associated oral pathoses treated with TCA. A prospective cohort study was performed in 20 patients who attended a dental consultation at 2 universities in Cartagena, Colombia. Among the patients, 65% were diagnosed as having focal epithelial hyperplasia, 20% as having verrucae vulgares, and 15% as having condylomata acuminata. Application of TCA to HPV-associated oral lesions proved to be a useful nonsurgical alternative treatment, as the resolution of the lesions was achieved atraumatically in a span of 45 days with 3 applications of 30-60 seconds each.
