Threading warts: a beauty parlor dermatosis.

Threading is a common beauty parlor procedure usually performed to shape the eyebrows and remove unwanted facial hair for cosmetic reasons. Appearance of warts at the site of threading is an unusual phenomenon. We report two such cases, first as koebnerization from the initial lesion elsewhere on the patient's body and second, possibly from the infected material at the beauty parlor. We emphasize the importance of identification of this condition and discuss its dermatological and cosmetological perspectives.
