Diagnosis: Lymphogranuloma venereum
A 28-year-old male presents with painful inguinal buboes following a self-resolving genital ulcer. The patient reports a history of unprotected sexual encounters in the past month, raising suspicion for a sexually transmitted infection. This case highlights the clinical presentation and management of a common but often overlooked condition in sexually active individuals.
A 28-year-old male presents with painful inguinal buboes that developed after experiencing a self-limited genital ulcer lasting approximately two weeks. On examination, there is notable bilateral swelling of the inguinal lymph nodes, which are tender to palpation. The genital examination reveals no active lesions, and there is no evidence of systemic illness.Bilateral inguinal lymphadenopathy: Enlarged, tender lymph nodes observed on both sides.History of genital ulcer: Previous ulceration that healed spontaneously.No systemic symptoms: Patient denies fever, chills, or malaise.Sexual history: Recent unprotected sexual encounters reported.No prior treatment: Patient has not received any treatment for the ulcer or lymphadenopathy.
The patient reports the onset of a genital ulcer approximately two weeks prior to presentation, which healed without intervention. He noted the development of painful inguinal swelling following the ulcer's resolution. His sexual history is significant for multiple partners and inconsistent use of protection. There is no significant past medical history, and he denies any known exposure to sexually transmitted infections. He is otherwise healthy, with no relevant family history.Onset: Genital ulcer appeared two weeks prior to the presentation.Triggers: Multiple unprotected sexual encounters noted.Prior treatments: No previous treatments for genital lesions or lymphadenopathy.Social history: Engages in high-risk sexual behavior.Exposure history: No known exposure to STIs prior to this incident.
Acute / First-Line ManagementDoxycycline: 100 mg orally twice daily for 21 days is the recommended first-line treatment for lymphogranuloma venereum.Alternative: Azithromycin 1 g orally in a single dose may be considered in cases where doxycycline is contraindicated.Workup and Diagnostic ConfirmationSerologic testing: Nucleic acid amplification tests (NAAT) for Chlamydia trachomatis are essential for diagnosis.Culture: Although not routinely performed, cultures can confirm the presence of C. trachomatis.HIV testing: Recommended for all patients presenting with STIs.Long-Term ManagementFollow-up: Patients should be re-evaluated within 1-2 weeks of initiating therapy to assess response.Partner notification: Sexual partners should be informed and treated as appropriate to prevent reinfection.Prevention: Education on safe sex practices is crucial to reduce the risk of future STIs.
Granuloma inguinale: Characterized by painless genital ulcers and associated with Donovan bodies on histology.Syphilis: Primary chancre may present similarly; serologic testing is key for diagnosis.Herpes simplex virus (HSV) infection: Typically presents with painful vesicular lesions; PCR or serology can confirm.HIV acute retroviral syndrome: Considered in cases with systemic symptoms and lymphadenopathy; HIV testing is essential.Candidiasis: May cause discomfort but usually lacks significant lymphadenopathy; localized examination reveals yeast infection signs.Non-specific lymphadenitis: Often due to bacterial infections; typically presents with unilateral lymphadenopathy.Actinomycosis: Can cause chronic indurated lesions and lymphadenopathy; associated with poor oral hygiene.Cat-scratch fever: Presents with regional lymphadenopathy following a cat scratch; serologic testing can confirm.
High-Yield PearlsHigh-risk populations: Lymphogranuloma venereum predominantly affects sexually active individuals, particularly men who have sex with men.Clinical course: Initial genital ulceration may be self-limiting, but progression to painful lymphadenopathy is common.Diagnostics: NAATs are the gold standard for diagnosing Chlamydia infections, including LGV.Empiric treatment: Initiate treatment promptly in suspected cases to prevent complications and transmission.Partner management: Engage in partner notification and treatment to control the spread of infection.Remember: Early recognition and treatment of lymphogranuloma venereum can prevent significant morbidity and transmission.
