Overview

Herpes genitalis, a common cause of genital ulcers

Genital ulcer disease (GUD) refers to the presence of ulcers, or open sores, on the genital area. These ulcers can be caused by a variety of infectious and non-infectious conditions. The most common infectious causes include sexually transmitted infections (STIs) such as herpes simplex virus (HSV), syphilis, and chancroid. Non-infectious causes can include Behçet's disease and trauma.

Causes

Infectious Causes

• Herpes simplex virus (HSV): HSV is the most common cause of genital ulcers worldwide. It is characterized by painful vesicular lesions that can recur over time.
• Syphilis: Caused by the bacterium Treponema pallidum, syphilis can present with a painless ulcer known as a chancre during its primary stage.
• Chancroid: A bacterial infection caused by Haemophilus ducreyi, chancroid presents with painful ulcers and swollen lymph nodes.
• Lymphogranuloma venereum: Caused by certain types of Chlamydia trachomatis, this condition can lead to genital ulcers and lymphadenopathy.

Non-Infectious Causes

• Behçet's disease: An inflammatory disorder that can cause recurrent oral and genital ulcers.
• Trauma: Physical injury to the genital area can result in ulceration.

Symptoms

Symptoms of genital ulcer disease can vary depending on the underlying cause but generally include:

• Pain or discomfort in the genital area
• Open sores or ulcers
• Swelling or redness around the ulcers
• Possible discharge from the ulcers
• Swollen lymph nodes in the groin

Diagnosis

Diagnosis of genital ulcer disease involves a combination of clinical examination, patient history, and laboratory tests. Common diagnostic methods include:

• Polymerase chain reaction (PCR) testing for HSV
• Serological tests for syphilis, such as the rapid plasma reagin (RPR) test
• Culture or PCR for Haemophilus ducreyi in cases of suspected chancroid

Treatment

Treatment of genital ulcer disease depends on the underlying cause:

• Antiviral drugs such as acyclovir or valacyclovir are used to treat HSV infections.
• Antibiotics like penicillin are effective for syphilis, while azithromycin or ceftriaxone can be used for chancroid.
• Management of non-infectious causes may involve immunosuppressive drugs or corticosteroids.

Prevention

Preventive measures for genital ulcer disease include:

• Practicing safe sex, including the use of condoms
• Regular STI screening and prompt treatment of infections
• Vaccination where applicable, such as the HPV vaccine
