Pus Filled Bump in Vagina

Pus filled bumps around the vagina is a fairly common symptom in women. These are called pustular eruptions (puss filled -> pustular).

The Most Common Cause

The most common cause of such pustular eruptions in the area around the vagina is folliculitis. Infection of the hair follicle of the skin is known as folliculitis.

Cause: Folliculitis presents as a pus filled bump (pustular eruption) on the skin. It might be caused by use of razors for removing hairs from the area around the vagina, but most often occurs spontaneously. A very similar condition is furuncles. Furuncles are deeper infections of the hair follicles and these also present with pustular eruptions.

Treatment: In most of the cases, the folliculitis usually is self-limiting even without any treatment. However, sometimes the infection may spread, and the pus filled bump may enlarge to form a painful furuncle (boil). This often ruptures, discharging the pus.

Prevention: Although nothing guarantees total prevention of such lesions, certain steps may help in reducing the risk of acquiring them.

Other Rare Causes

Can It Be Sexually Transmitted Diseases?

A common worry among the women having such pustular lesions around the vagina for the first time is that if this is a sexually transmitted disease (especially herpes).

Although vesicular (clear fluid-filled bumps) eruptions do occur in the initial stages of herpes, and they may sometimes be pustular (look like pus-filled bumps around the vagina), these pustular lesions are unlikely to be due to herpes. Absence of severe pain and any other symptoms nearly rules out herpes infection as a possible cause of such pus-filled bumps around the vagina.

Chances of it being any other sexually transmitted disease are also extremely low. The lesions of many STDs may initially be variable to start with before they grow into painful/painless ulcers. These initial lesions might rarely be a raised pus-filled bump. These initial lesions in STDs usually last for a day or two and then ulcerate to form the classic ulcerative lesions of the sexually transmitted diseases. Only Chancroid consistently presents with pus filled bump initially, but for a maximum of two days only, after which the typical ulcers are formed.

Lesions of molluscum contagiosum, another sexually transmitted disease, may appear as a bump in the area around the vagina. However, often it is clear by its appearance that it is not pus filled.

Lymphogranuloma Venereum in the initial stage might only present with 'bump' lesions around the vagina, but these are filled with clear fluid rather than pus. Sometimes it may not be clearly evident that whether such lesions are pus filled or fluid filled. Other than these conditions, typical presentation of no other sexually transmitted disease will result in pus-filled bump around the vagina.
