Lymphogranuloma venereum
LGV; Lymphogranuloma inguinale; Lymphopathia venereum
Lymphogranuloma venereum (LGV) is a sexually transmitted bacterial infection.
Causes
Lymphogranuloma venereum (LGV) is a long-term (chronic) infection of the lymphatic system. It is caused by any of 3 different types (serovars) of the bacteria Chlamydia trachomatis. The bacteria are spread by sexual contact. The infection is not caused by the same bacteria that cause genital chlamydia .
Chlamydia
Chlamydia is an infection. It is caused by the bacteria Chlamydia trachomatis. It is most often spread through sexual contact.
LGV is more common in Central and South America than in North America.
LGV is more common in men than women. The main risk factor is being HIV-positive.
Symptoms
Symptoms of LGV can begin a few days to a month after coming in contact with the bacteria. Symptoms include:
- Drainage through the skin from lymph nodes in the groin
-
Painful bowel movements (
tenesmus
)
Tenesmus
Tenesmus is the feeling that you need to pass stools, even though your bowels are already empty. It may involve straining, pain, and cramping....
- Small painless sore on the male genitals or in the female genital tract
- Swelling and redness of the skin in the groin area
- Swelling of the labia (in women)
- Swollen groin lymph nodes on one or both sides; it may also affect lymph nodes around the rectum in people who have anal intercourse
-
Blood or pus from the rectum (
blood in the stools
)

Exams and Tests
The health care provider will examine you and ask about your medical and sexual history. Tell your provider if you had sexual contact with someone you think has had symptoms of LGV.
A physical exam may show:
- An oozing, abnormal connection (fistula) in the rectal area
- A sore on the genitals
- Drainage through the skin from lymph nodes in the groin
- Swelling of the vulva or labia in women
-
Swollen lymph nodes in the groin (inguinal
lymphadenopathy
)
Lymphadenopathy
Lymphofollicular hyperplasia is an increase in the size of the lymph node follicles. These follicles contain normal white blood cells called lymphoc...
Tests may include:
-
Biopsy
of the lymph node
Biopsy
A biopsy is the removal of a small piece of tissue for laboratory examination.
- Blood test for the bacteria that causes LGV
- Laboratory test to detect chlamydia
Treatment
LGV is treated with antibiotics, including doxycycline and erythromycin.
Outlook (Prognosis)
With treatment, the outlook is good.
Possible Complications
Health problems that may result from LVG infection include:
-
Abnormal connections between the rectum and vagina (
fistula
)
Fistula
A fistula is an abnormal connection between 2 body parts, such as an organ or blood vessel and another structure. Fistulas are usually the result of...
-
Brain inflammation (
encephalitis
- very rare)
Encephalitis
Encephalitis is irritation and swelling (inflammation) of the brain, most often due to infections.
- Infections in the joints, eyes, heart, or liver
- Long-term inflammation and swelling of the genitals
- Scarring and narrowing of the rectum
Complications can occur many years after you are first infected.
When to Contact a Medical Professional
Call your provider if:
- You have been in contact with someone who may have a sexually transmitted infection, including LGV
- You develop symptoms of LGV
Prevention
Not having any sexual activity is the only way to prevent a sexually transmitted infection. Safer sex behaviors may reduce the risk.
The proper use of condoms, either the male or female type, greatly decreases the risk of catching a sexually transmitted infection. You need to wear the condom from the beginning to the end of each sexual activity.

Lymphatic system - illustration
The lymphatic system filters fluid from around cells. It is an important part of the immune system. When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes. Common areas where lymph nodes can be easily felt, especially if they are enlarged, are: the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).
