How does lymphogranuloma venereum begin and progress?

Lymphogranuloma venereum is an infection caused by the microorganism Chlamydia trachomatis.12

Progression of the Disease

• Primary Stage: The infection begins with a primary lesion, typically appearing on the genitalia 3 to 21 days after exposure. This initial blister is often transient and may go unnoticed.12
• Secondary Stage: Approximately 10 to 30 days after exposure, the disease manifests as a hot, tender swelling of the lymph nodes in the groin, known as buboes. This stage may be accompanied by systemic symptoms such as fever, chills, headache, and joint pains. Abscess formation and the drainage of pus from the inguinal lymph nodes are common.1
• Late Manifestations: If left untreated, the disease can progress to severe complications, including secondary ulceration, elephantiasis (enlargement) of the genitalia in men, and inflammation, ulceration, and stricture of the rectum. In rare instances, it may involve the nervous system, arthritis, or conjunctivitis.12

The course of the infection varies significantly, ranging from asymptomatic cases to extreme debilitation. Treatment typically involves broad-spectrum antibiotics.12
