<P> Bacterial infections include: chancroid--characterised by genital ulcers known as chancres; granuloma inguinale showing as inflammatory granulomas often described as nodules; syphilis--the primary stage classically presents with a single chancre, a firm, painless, non-itchy ulcer, but there may be multiple sores; and gonorrhea that very often presents no symptoms but can result in discharge . </P> <P> Viral infections include human papillomavirus infection (HPV)--this is the most common STI and has many types . Genital HPV can cause genital warts . There have been links made between HPV and vulvar cancer, though HPV most often causes cervical cancer . Genital herpes is mostly asymptomatic but can present with small blisters that break open into ulcers . HIV / AIDS is mostly transmitted through sexual activity, and the vulva in some cases can be affected by sores . A highly contagious viral infection is molluscum contagiosum which is transmissible on close contact and causes watery warts . </P> <P> Parasitic infections include trichomoniasis, pediculosis pubis, and scabies . Trichomoniasis is transmitted by a parasitic protozoan and is the most common non-viral STI . Most cases are asymptomatic but may present symptoms of irritation and a discharge of unusual odor . Pediculosis pubis commonly called crabs, is a disease caused by the crab louse an ectoparasite . When the pubic hair is infested the irritation produced can be intense . Scabies, also known as the "seven year itch", is caused by another ectoparasite, the mite Sarcoptes scabiei, giving intense irritation . </P> <P> Many malignancies can develop in vulvar structures . Most vulvar cancers are squamous cell carcinomas and are usually found in the labia particularly the labia majora . The second most common vulval cancer (though not very common) is vulval melanoma . Signs and symptoms can include: itching, or bleeding; skin changes including rashes, sores, lumps or ulcers, and changes in vulval skin coloration . Pelvic pain might also occur especially during urinating and sex . Vulval melanoma usually affects women over the age of fifty, and affects white women more than black women . A vulvectomy may need to be performed in order to remove some or all of the vulva . This procedure is usually performed as a last resort in certain cases of cancer, vulvar dysplasia or vulvar intraepithelial neoplasia . </P>
