History
The clinical course of LGV consists of the following stages:
- First stage (primary LGV)
- This stage occurs 3-30 days after inoculation.
- Primary LGV begins as a small, painless papule or pustule that may erode to form a small, asymptomatic herpetiform ulcer that usually heals rapidly without scarring.
- The most common sites of infection for men include the coronal sulcus, prepuce, glans, and scrotum. Rarely, symptoms of urethritis occur.
- The most common sites of infection in women include the posterior vaginal wall, posterior cervix, fourchette, and vulva.
- The initial lesion, especially in women, often goes unnoticed by the patient.
- Second stage (secondary LGV)
- Secondary LGV begins 2-6 weeks after the primary lesion.
- This second stage consists of painful regional lymphadenopathy (usually in the inguinal and/or femoral lymph nodes).
- Painful, swollen lymph nodes coalesce to form buboes, which may rupture in as many as one third of patients. Those that do not rupture harden, then slowly resolve.
- Inguinal lymphadenopathy occurs in only 20-30% of females with LGV; they more typically have involvement of the deep iliac or perirectal nodes and may only present with nonspecific back and/or abdominal pain.
- This stage is when most men present and are diagnosed; most women are not diagnosed in this stage because of their lack of inguinal lymphadenopathy.
- Constitutional symptoms associated with the second stage include fever, chills, myalgias, and malaise.
- Systemic spread may lead to the following conditions:
- Arthritis
- Ocular inflammatory disease
- Cardiac involvement
- Pulmonary involvement
- Aseptic meningitis
- Hepatitis or perihepatitis
- Third stage (tertiary LGV)
- Tertiary LGV is termed genitoanorectal syndrome.
- This condition is more common in women, secondary to their lack of symptoms during the first two stages.
- Rectal involvement is more common in men who have sex with men and in women who practice anal-receptive intercourse.
- Tertiary LGV is characterized by proctocolitis.
- FUO
- Symptoms include the following conditions:
- Bloody purulent discharge
- Rectal pain
- Tenesmus
Physical
Large fluctuant buboes or any otherwise unexplained perianal deformity in a young female should suggest a diagnosis of LGV.
- First stage (primary LGV)
- The initial lesion is usually a small, unnoticed painless papule, shallow ulcer, or herpetiform lesion in the genital area.
- Initial lesions may be differentiated from the more common herpetic lesions by the lack of pain associated with the lesion. Differentiation from a syphilitic chancre is more problematic and requires serologic testing.
- Second stage (secondary LGV)
- Secondary LGV is characterized by painful lymph nodes (usually unilateral) known as buboes.
- Enlargement of the inguinal nodes above and the femoral nodes below the inguinal ligament leads to the classic groove sign, which is observed in one third of affected men.
- Inguinal lymphadenopathy results from a primary lesion of the anterior vulva, penis, or urethra.
- Perirectal or pelvic lymphadenopathy results from a primary lesion involving the posterior vulva, vagina, or anus.
- Affected nodes often coalesce and form abscesses, which can rupture and form sinus tracts.
- Third stage (tertiary LGV)
- Tertiary LGV most often manifests in women.
- Patients initially develop proctocolitis.
- Patients may present with perirectal fistulas, abscesses, strictures, and rectal stenosis.
- Hyperplasia of intestinal and perirectal lymphatics may form lymphorrhoids, which are similar to hemorrhoids.
- Patients may develop strictures and fistulous tracts secondary to repeated tissue scarring and repair.
- Enlargement, thickening, and fibrosis of the labia may occur in women, a condition termed esthiomene.
- Chronic lymphatic obstruction may lead to elephantiasis of the genitals.
- Penile and scrotal edema and distortion have been termed saxophone penis.
Causes
The L1, L2, and L3 serovars of C trachomatis cause LGV. Risk factors include residing in or visiting endemic areas, practicing anal-receptive intercourse, eschewing condoms, and working in the commercial sex trade.
