Chancroid What is chancroid? Chancroid is an infection caused by the bacterium Hemophilus ducreyi, which is passed from one sexual partner to another. It begins in a sexually exposed area of the genital skin, most commonly the penis and vulva the female external genital organs including the labia, clitoris, and entrance to the vagina.
Chancroid starts out as a tender bump that emerges 3 to10 days the incubation period after the sexual exposure. The cells that form the bump then begin to die, and the bump becomes an ulcer an open sore that is usually painful. Often, there is an associated tenderness and swelling of the glands lymph nodes in the groin that normally drain lymph tissue fluid from the genital area; however, the painful ulcer and tender lymph nodes occur together in only about one-third of infections.
Chancroid is common in developing countries but is a relatively rare cause of genital ulcers in the U. Diagnosis of chancroid A clinical diagnosis of chancroid which is made from the medical history and physical examination can be made if the patient has one or more painful ulcers in the genital area and tests are negative for syphilis or herpes.
The word chancroid means resembling a chancre, the genital ulcer that is caused by syphilis. Chancroid sometimes is called soft chancre to distinguish it from the chancre of syphilis that feels hard to the touch. The ulcer of chancroid also is painful, unlike the ulcer of syphilis that is painless.
The diagnosis of chancroid can be confirmed by a culture of the material from within the ulcer for the bacterium Hemophilus ducreyi.
The clinical diagnosis justifies the treatment of chancroid even if cultures are not available.
Treatment of chancroid Chancroid is almost always cured with a single oral dose of azithromycin Zithromax or a single injection of ceftriaxone Rocephin. Alternative medications are ciprofloxacin Cipro or erythromycin. Whichever treatment is used, the ulcers should improve within seven days. If no improvement is seen after treatment, the patient should be reevaluated for causes of ulcers other than chancroid.
HIV-infected individuals are at an increased risk for failing treatment for chancroid and should be observed closely to assure that the treatment has been effective. What should a person do if exposed to someone with chancroid? A health care professional should evaluate anyone who has had sexual contact with a person with chancroid.
Whether or not exposed individuals have an ulcer, they should be treated. Pubic lice and scabies ectoparasitic infections What are ectoparasitic infections? Ectoparasitic infections are infections that are caused by tiny parasitic bugs, such as lice or mites.

Pubic lice pediculosis pubis Pediculosis pubis is an infection of the genital area caused by the crab louse Phthirus pubis. The lice commonly called crabs are small bugs that are visible to the naked eye without the aid of a magnifying glass or microscope.
The lice live on pubic hair or any other hair and are associated with itching. Alternative treatments include pyrethrins with piperonyl butoxide applied for 10 minutes before washing off.
None of these treatments should be used for involvement near the eyes because they can be very irritating. All sexual partners within the preceding month should be treated for pubic lice and evaluated for other STDs.
