Background

  • Cased by L1, L2, L3 serovars of Chlamydia trachomatis[1]
  • Sexually transmitted
  • Often co-infected with HIV
  • More common in tropical and sub-tropical climates

Clinical Features[1]

  • Incubation period 3-30 days
  • Stage 1 (Primary): Self-limited painless genital papule/ulcer (lasts ~2-3 days)
    • Seen on coronal sulcus in men, posterior vaginal fourchette in women
    • Can also occur in rectum (hemorrhagic proctitis), urethra, vagina
  • Stage 2 (Secondary): Painful inguinal and/or femoral lymphadenopathy (2-6 weeks after primary lesion)
    • Lymph nodes become necrotic → suppurative → formation of buboes
      • Fluctuant lymph nodes classically form a "groove sign" when adenopathy extends above and below the inguinal ligament
    • Systemic symptoms: fever, myalgia, malaise
      • Occasionally - arthritis, ocular, cardiac, pulmonary, aseptic meningitis, hepatitis
  • Stage 3 (Tertiary): Proctocolitis, anorectal syndrome
    • Usually manifests in women or men who have sex with men
    • Rectal pain, discharge, bleeding
    • Can also → fistula, abscess, strictures, megacolon

Differential Diagnosis

Sexually transmitted diseases

Evaluation

  • Nucleic Acid Amplification Tests (NAAT)
  • Immunofluorescence
  • Culture (needle aspiration of bubo)
  • Serology
  • Consider anoscopy
  • Also consider testing for HIV and other possible coinfections

Management [2]

  • Doxycycline 100mg PO BID x 21 days (first choice) OR
  • Erythromycin 500mg PO QID x 21 days OR
    • Preferred for pregnant and lactating females
  • Azithromycin 1g PO weekly for 3 weeks OR
    • Alternative for pregnant women - poor evidence for this treatment currently
  • Tetracycline, Minocycline, or Moxifloxacin (x21 days) are also acceptable alternatives to Doxycycline
  • Treat sexual partner

Disposition

  • Discharge
  • Instruct patient to abstain from sexual activities until completion of treatment
