  • Management
  1. General
    1. Cause may not be indentified on lab testing in more than 25% of cases
    2. Treatment may be empiric based on history and examination
    3. Sexual partners should be tested for Sexually Transmitted Disease
    4. Abstain from sexual activity until ulcers have healed and treatment is completed
      1. HIV Transmission is at much higher risk when Genital Ulcers are present
  2. Initial empiric management (start before lab results back)
    1. Genital Herpes treatment (start early to prevent HSV transmission, HIV Transmission and speed healing)
    2. Withdraw medications suspected as cause of possible Fixed Drug Eruption (diagnosis of exclusion)
    3. Consider empiric Syphilis management while awaiting results in high risk patients (e.g. Men who have Sex with Men)
  3. Cause Specific Management
    1. Genital Herpes
    2. Primary Syphilis
    3. Chancroid
    4. Lymphogranuloma venereum (Donovanosis)
    5. Behcet Syndrome
  4. Ulcer Treatment
    1. Keep ulcers clean and bandaged
    2. Sitz baths may be soothing
    3. Various antimicrobials (e.g. silvadene) have been used but are without evidence to support
    4. Consider cool compress with Burow Solution
  • Prevention
  1. Limit number of sexual partners
  2. Consistent Condom use
  3. Regular Sexually Transmitted Infection Screening
