title: [Genital ulcers--what's new?].
abstract: The most common infectious causes of genital ulcers are herpes simplex virus and syphilis. However, mixed infections can occur and genital ulcer may increase the risk of acquiring human immunodeficiency virus. Although the history and physical examination can narrow the differential diagnosis, there is a need for initial routine laboratory testing for the most common pathogens that includes: for syphilis: serologic screening and dark field examination of the lesion; for herpes simplex virus: serology, vial culture and/or polymerase chain reaction. Human immunodeficiency testing is mandatory. Recently, some clinical laboratories adapted the reverse screening algorithm for syphilis (initial treponemal test, and, if positive, followed by non-treponemal test) that may potentially lead to overtreatment. Early and prompt therapy may decrease the risk of transmission of the infectious agent to others. This article reviews the infectious pathogens causing genital ulcers, their unique clinical manifestation, diagnosis and treatment.
