What stage of Lymphogranuloma venereum presents with lymphadenitis?

Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by certain strains of the Chlamydia trachomatis bacterium. It progresses through various stages, and understanding these stages is crucial for diagnosis and treatment.

Stage 2 of LGV is characterized by the development of lymphadenitis, which is a significant hallmark of this stage. In this phase, the infection spreads to the lymph nodes, causing them to become swollen, tender, and sometimes painful. Patients may experience buboes, which are enlarged lymph nodes, particularly in the groin region. This lymphadenitic response is indicative of the body's immune reaction to the infection, and recognizing it is essential for appropriate intervention.

In contrast, the earlier stages do not typically present with such pronounced lymphadenopathy. Stage 1 usually involves the formation of a small, painless ulcer at the site of infection. Later stages may involve more systemic symptoms, but it is in Stage 2 where the hallmark feature of lymphadenitis becomes prominent. Thus, the correct association of lymphadenitis with Stage 2 highlights the importance of this stage in the clinical progression of LGV.
