== Lymphogranuloma venereum ==
Lymphogranuloma venereum is an STD caused by Chlamydia trachomatis serotypes L1-L3. It’s most common in tropical and subtropical countries.

In the primary stage, the patient has small, painless genital ulcers that heal within a few days. In the secondary stage, painful swelling of inguinal lymph nodes with abscess formation occurs.

Diagnosis is by PCR, and treatment is with doxycycline.

== Genital herpes ==
Genital herpes is an STD caused by HSV-2 in most cases, but rarely HSV-1.

It’s often asymptomatic, but it can cause painful ulcerative vesicles to form on the genitals. Painful inguinal lymphadenopathy may also occur.

The virus may then return to be latent in lumbar or sacral ganglia, from which it can reactivate later. Reactivation is most common during stress or immunosuppression.

It can be diagnosed based on either of the following:

* Light microscopy with a Tzanck smear
* Viral culture
* PCR

Treatment involves topical or oral valacyclovir, famciclovir, or acyclovir.

== Genital warts ==
Genital warts (condyloma acuminata) are caused by infection by HPV 6 or 11. These warts are painless, like condyloma lata.

It can be treated by topical podophyllotoxin solution or surgical excision.
