Synopsis
There are 3 distinct stages in the course of the disease. After a 3- to 30-day incubation period, a small, painless papule or pustule develops that may erode to form an ulceration. This lesion is often asymptomatic and heals without scarring within 1 week. The second, or inguinal, stage begins 2-6 weeks after the primary lesion and consists of painful inflammation of the inguinal and/or femoral lymph nodes.
The third stage of disease in LGV is called the genito-anorectal syndrome. In women in particular, it may present after asymptomatic first and second stages. Patients initially present in the third stage with proctocolitis, followed by perirectal abscesses, strictures, fistulas, and rectal stenosis.
