Overview
Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by specific serovars of Chlamydia trachomatis, characterized by inguinal lymphadenopathy, often progressing from genital ulcers to suppurative abscesses and fistulas. 1Diagnosis
Clinical Presentation: Abnormal tonsillar tissue, resembling cervical lymphadenopathy.
Histological Examination: Essential for confirming diagnosis in atypical presentations like tonsillar involvement. 1
Laboratory Tests: Nucleic acid amplification tests (NAAT) for Chlamydia trachomatis DNA are highly sensitive and specific.
Serotyping: Required to differentiate LGV serovars (L1-L3) from other Chlamydia infections.Management
First-Line Treatment: Doxycycline 100 mg orally twice daily for 10-14 days.
Alternative for Penicillin Allergy: Erythromycin or azithromycin (consider resistance patterns).
Supportive Care: Pain management, wound care for abscesses, and monitoring for complications.Special Populations
Pregnancy: Azithromycin is preferred over doxycycline due to safety concerns with tetracyclines during pregnancy. 1Key Recommendations
Perform histological examination of abnormal tonsillar tissue to confirm LGV diagnosis when clinical suspicion is high. (Evidence: Moderate) 1
Use nucleic acid amplification tests for definitive laboratory diagnosis of LGV. (Evidence: Strong)
Treat LGV with doxycycline for 10-14 days; switch to azithromycin in cases of penicillin allergy or pregnancy. (Evidence: Moderate) 1References
