The presence of unusual lumps in the wall or base of the vagina is always abnormal. The most common of these is Bartholin's cyst. The cyst, which can feel like a pea, is formed by a blockage in glands which normally supply the opening of the vagina. This condition is easily treated with minor surgery or silver nitrate. Other less common causes of small lumps or vesicles are herpes simplex. They are usually multiple and very painful with a clear fluid leaving a crust. They may be associated with generalized swelling and are very tender. Lumps associated with cancer of the vaginal wall are very rare and the average age of onset is seventy years. The most common form is squamous cell carcinoma, then cancer of the glands or adenocarcinoma and finally, and even more rarely, melanoma.

Vaginal hypoplasia is the underdevelopment or incomplete development of the vagina. Vaginal hypoplasia can vary in severity from being smaller than normal to being completely absent. The absence of a vagina is a result of vaginal agenesis. Diagnostically, it may look similar to a vaginal obstruction. It is frequently associated with Mayer-Rokitansky-Küstner-Hauser (MRKH) syndrome, in which the most common result is an absent uterus in conjunction with a deformed or missing vagina, despite the presence of normal ovaries and normal external genitalia. It is also associated with cervical agenesis, in which the uterus is present but the uterine cervix is absent.

Foreign objects can cause a chronic vaginal discharge with a foul odor. Common foreign objects found in adolescents and adults are tampons, toilet paper, and objects used for sexual arousal.

Chlamydia and gonorrhea can also cause vaginal discharge, though more often than not these infections do not cause symptoms. The vaginal discharge in Chlamydia is typically pus-filled, but it is important to note that in around 80% of cases Chlamydia does not cause any discharge. Gonorrhea can also cause pus-filled vaginal discharge, but Gonorrhea is similarly asymptomatic in up to 50% of cases. If the vaginal discharge is accompanied by pelvic pain, this is suggestive of pelvic inflammatory disease (PID), a condition in which the bacteria have moved up the reproductive tract.

A woman may have vaginal itching or burning and may notice a discharge.

The discharge may be excessive in amounts or abnormal in color(such as yellow, gray, or green).

The following symptoms may indicate the presence of infection:

- Irritation or itching of the genital area

- inflammation (irritation, redness, and swelling caused by the presence of extra immune cells) of the labia majora, labia minora, or perineal area

- vaginal discharge

- foul vaginal odor

- pain/irritation with sexual intercourse

Common symptoms include increased vaginal discharge that usually smells like fish. The discharge is often white or gray in color. There may be burning with urination. Occasionally, there may be no symptoms.

The discharge coats the walls of the vagina, and is usually without significant irritation, pain, or erythema (redness), although mild itching can sometimes occur. By contrast, the normal vaginal discharge will vary in consistency and amount throughout the menstrual cycle and is at its clearest at ovulation—about two weeks before the period starts. Some practitioners claim that BV can be asymptomatic in almost half of affected women, though others argue that this is often a misdiagnosis.

Leukorrhea or (leucorrhoea British English) is a thick, whitish or yellowish vaginal discharge. There are many causes of leukorrhea, the usual one being estrogen imbalance. The amount of discharge may increase due to vaginal infection or STDs, and it may disappear and reappear from time to time. This discharge can keep occurring for years, in which case it becomes more yellow and foul-smelling. It is usually a non-pathological symptom secondary to inflammatory conditions of vagina or cervix.

Leukorrhea can be confirmed by finding >10 WBC under a microscope when examining vaginal fluid.

Vaginal discharge is not abnormal, and causes of change in discharge include infection, malignancy, and hormonal changes. It sometimes occurs before a girl has her first period, and is considered a sign of puberty.

Vaginitis is inflammation of the vagina. In most cases, it is a symptom of an infection of the vagina. Vulvovaginitis, is an inflammation of the vagina and vulva. Infection can result in discharge, itching and pain.

The three main causes of vaginitis are infections by bacteria (bacterial vaginosis), yeast (vaginal candidiasis), or the protozoan that causes trichomoniasis. A woman may have multiple infections at any one time. If there is discomfort in the vulvovaginal area, women can request their health care providers evaluate for the presence of an infection.

There are often no symptoms associated with a urethrocele. When present, symptoms include stress incontinence, increased urinary frequency, and urinary retention (difficulty in emptying the bladder). Pain during sexual intercourse may also occur.

Where a urethrocele causes difficulty in urinating, this can lead to cystitis.

It may also result from inflammation or congestion of the vaginal mucosa. In cases where it is yellowish or gives off an odor, a doctor should be consulted since it could be a sign of several disease processes, including an organic bacterial infection (aerobic vaginitis) or STD.

After delivery, leukorrhea accompanied by backache and foul-smelling lochia (post-partum vaginal discharge, containing blood, mucus, and placental tissue) may suggest the failure of involution (the uterus returning to pre-pregnancy size) due to infection. A number of investigation such as wet smear, Gram stain, culture, pap smear and biopsy are suggested to diagnose the condition.

Vaginal flatulence is an emission or expulsion of air from the vagina. It may occur during or after sexual intercourse or during other sexual acts, stretching or exercise. The sound is somewhat comparable to flatulence from the anus but does not involve waste gases and thus often does not have a specific odor associated. Slang terms for vaginal flatulence include vart, queef, and fanny fart (mostly British).

The symptoms usually appear after a menstrual period. The most common are:

- Abnormal smell and colour of vaginal discharge

- Pain during ovulation

- Pain during sexual intercourse

- Pain coming and going during periods

- Abdominal pain

- Lower back pain

- Fever

- Nausea

- Vomiting

- Bloating

The infection usually has its origin in the vagina and ascends to the Fallopian tube from there. Because the infection can spread via the lymph vessels, infection in one Fallopian tube usually leads to infection of the other.

Vaginal gas that involves strong odor or fecal matter may be a result of colovaginal fistula, a serious condition involving a tear between the vagina and colon, which can result from surgery, child birth, diseases (such as Crohn's disease), and other causes. This condition can lead to urinary tract infection and other complications. Vaginal gas can also be a symptom of an internal female genital prolapse, a condition most often caused by childbirth.

Puffs or small amounts of air passed into the vaginal cavity during cunnilingus will not cause any known issues, however "forcing" or purposely blowing air at force into the vaginal cavity can cause an air embolism, which in very rare cases can be potentially dangerous for the woman, and if pregnant, for the fetus.

The symptoms of vaginal thrush include vulval itching, vulval soreness and irritation, pain or discomfort during sexual intercourse (superficial dyspareunia), pain or discomfort during urination (dysuria) and vaginal discharge, which is usually odourless. This can be thin and watery, or thick and white, like cottage cheese.

As well as the above symptoms of thrush, vulvovaginal inflammation can also be present. The signs of vulvovaginal inflammation include erythema (redness) of the vagina and vulva, vaginal fissuring (cracked skin), edema (swelling from a build-up of fluid), also in severe cases, satellite lesions (sores in the surrounding area). This is rare, but may indicate the presence of another fungal condition, or the herpes simplex virus (the virus that causes genital herpes).

Vulvovaginal health is the health and sanitation of the human vulva and vagina.

Problems affecting this area include vulva diseases, vaginal diseases and urinary tract infections.

Eugonadotropic primary amenorrhea and cyclical lower abdominal pain are the chief presenting complaints of hematocolpos. Patient may be brought in emergency urinary retention.

The symptoms of urethritis can include pain or a burning sensation upon urination (dysuria), a white/cloudy discharge and a feeling that one needs to pass urine frequently. For men, the signs and symptoms are discharge from the penis, burning or pain when urinating, itching, irritation, or tenderness. In women, the signs and symptoms are discharge from vagina, burning or pain when urinating, anal or oral infections, abdominal pain, or abnormal vaginal bleeding, which may be an indication that the infection has progressed to Pelvic Inflammatory Disease.

NGU is transmitted by touching the mouth, penis, vagina or anus by penis, vagina or anus of a person who has NGU.

NGU is more common in men than women. Men may have a discharge (strange liquid) from the penis, pain when urinating, and itching, irritation or tenderness around the opening of the penis. Women might not have any symptoms and may not know they have NGU until severe problems occur. Women might have discharge from the vagina, burning or pain when urinating, pain in the abdominal (stomach) area, or bleeding from the vagina that is not from a monthly period. (This may be an sign that NGU has become worse and turned into Pelvic Inflammatory Disease, or PID).

Vulvitis is inflammation of the vulva, the external female mammalian genitalia that include the labia majora, labia minora, clitoris, and introitus (the entrance to the vagina). It may co-occur with vaginitis, inflammation of the vagina, and may have infectious or non-infectious causes.

Complicated thrush is four or more episodes of thrush in a year or when severe symptoms of vulvovaginal inflammation are experienced. It is also complicated if coupled with pregnancy, poorly controlled diabetes, poor immune function, or the thrush is not caused by "Candida albicans".

Bacterial vaginosis (BV) is a disease of the vagina caused by excessive growth of bacteria. Common symptoms include increased vaginal discharge that often smells like fish. The discharge is usually white or gray in color. Burning with urination may occur. Itching is uncommon. Occasionally, there may be no symptoms. Having BV approximately doubles the risk of infection by a number of other sexually transmitted infections, including HIV/AIDS. It also increases the risk of early delivery among pregnant women.

BV is caused by an imbalance of the naturally occurring bacteria in the vagina. There is a change in the most common type of bacteria and a hundred to thousandfold increase in total numbers of bacteria present. Typically, bacteria other than "Lactobacilli" become more common. Risk factors include douching, new or multiple sex partners, antibiotics, and using an intrauterine device, among others. However, it is not considered a sexually transmitted infection. Diagnosis is suspected based on the symptoms, and may be verified by testing the vaginal discharge and finding a higher than normal vaginal pH, and large numbers of bacteria. BV is often confused with a vaginal yeast infection or infection with Trichomonas.

Usually treatment is with an antibiotic, such as clindamycin or metronidazole. These medications may also be used in the second or third trimesters of pregnancy. However, the condition often recurs following treatment. Probiotics may help prevent re-occurrence. It is unclear if the use of probiotics or antibiotics affects pregnancy outcomes.

BV is the most common vaginal infection in women of reproductive age. The percentage of women affected at any given time varies between 5% and 70%. BV is most common in parts of Africa and least common in Asia and Europe. In the United States about 30% of women between the ages of 14 and 49 are affected. Rates vary considerably between ethnic groups within a country. While BV like symptoms have been described for much of recorded history, the first clearly documented case occurred in 1894.

Cryptomenorrhea or cryptomenorrhoea, also known as hematocolpos, is a condition where menstruation occurs but is not visible due to an obstruction of the outflow tract. Specifically the endometrium is shed, but a congenital obstruction such as a vaginal septum or on part of the hymen retains the menstrual flow. A patient with cryptomenorrhea will appear to have amenorrhea but will experience cyclic menstrual pain. The condition is surgically correctable.

The patient usually presents at the age of puberty when the commencement of menstruation blood gets collected in the vagina and gives rise to symptoms.

Vulvitis, inflammation of the vulva, can have a variety of etiologies in children and adolescents, including allergic dermatitis, contact dermatitis, lichen sclerosus, and infections with bacteria, fungi, and parasites. Dermatitis in infants is commonly caused by a soiled diaper being left on for an extended period of time. Increasing the frequency of diaper changes and topical application of emollients are sufficient to resolve most cases. Dermatitis of the vulva in older children is usually caused by exposure to an irritant (e.g. scented products that come into contact with the vulva, laundry detergent, soaps, etc.) and is treated with preventing exposure and encouraging sitz baths with baking soda as the vulvar skin heals. Other treatment options for vulvar dermatitis include oral hydroxyzine hydrochloride or topical hydrocortisone.

Lichen sclerosus is another common cause of vulvitis in children, and it often affects an hourglass or figure eight-shaped area of skin around the anus and vulva. Symptoms of a mild case include skin fissures, loss of skin pigment (hypopigmentation), skin atrophy, a parchment-like texture to the skin, dysuria, itching, discomfort, and excoriation. In more severe cases, the vulva may become discolored, developing dark purple bruising (ecchymosis), bleeding, scarring, attenuation of the labia minora, and fissures and bleeding affecting the posterior fourchette. Its cause is unknown, but likely genetic or autoimmune, and it is unconnected to malignancy in children. If the skin changes are not obvious on visual inspection, a biopsy of the skin may be performed to acquire an exact diagnosis. Treatment for vulvar lichen sclerosus may consist of topical hydrocortisone in mild cases, or stronger topical steroids (e.g. clobetasol propionate). Preliminary studies show that 75% of cases do not resolve with puberty.

Organisms responsible for vulvitis in children include pinworms ("Enterobius vermicularis"), "Candida" yeast, and group A hemolytic "Streptococcus". Though pinworms mainly affect the perianal area, they can cause itching and irritation to the vulva as well. Pinworms are treated with albendazole. Vulvar "Candida" infections are uncommon in children, and generally occur in infants after antibiotic therapy, and in children with diabetes or immunodeficiency. "Candida" infections cause a red raised vulvar rash with satellite lesions and clear borders, and are diagnosed by microscopically examining a sample treated with potassium hydroxide for hyphae. They are treated with topical butoconazole, clotrimazole, or miconazole. "Streptococcus" infections are characterized by a dark red discoloration of the vulva and introitus, and cause pain, itching, bleeding, and dysuria. They are treated with antibiotics.

A Suprapubc bulge is caused by hematocolpos. Vaginal introitus shows a blue bulging membrane.
