Labial Bumps: Causes and Concerns for Women

Genital issues

Hello Doctor: Four days ago, I noticed a raised area on the left side of my labia majora near the vaginal opening, approximately 0.5 cm in diameter (not certain).
It feels somewhat like the skin after a mosquito bite, and the surface does not have any significant elevation or roughness; it does not hurt when touched or pressed, but sometimes it feels a bit itchy when not being touched.
The color appears to be slightly whiter than the surrounding area.
Over the past four days, there has been no noticeable change in size, no bleeding, or other symptoms, and I have not detected any unusual odor.
What could this condition be? Thank you! :)

Based on your description, it could be a common abscess or cellulitis, which may become red, swollen, warm, and painful in a few days.
These symptoms will gradually appear.

More Info

When it comes to labial bumps, there are several potential causes that can lead to the development of such lesions on the labia. Based on your description, it seems that you have a small, non-painful bump on the left side of your labia majora, which is not changing in size and is not associated with any bleeding or unusual discharge. Here are some common causes and considerations regarding labial bumps:
1. Sebaceous Cysts: These are small, non-cancerous lumps that can occur when sebaceous glands become blocked. They are typically painless and can feel smooth to the touch. They may appear white or yellowish and can sometimes become inflamed or infected, but in your case, it seems stable.

2. Folliculitis: This condition occurs when hair follicles become inflamed, often due to infection or irritation. It can present as small red or white bumps and may be itchy or tender. However, if you are not experiencing pain or significant discomfort, this may be less likely.

3. Bartholin's Gland Cysts: The Bartholin glands are located on either side of the vaginal opening and can become blocked, leading to the formation of a cyst. These cysts can vary in size and may be asymptomatic unless they become infected.

4. Genital Warts: Caused by the human papillomavirus (HPV), genital warts can appear as small, flesh-colored or white bumps. They may be itchy or cause discomfort, but they can also be asymptomatic. Given that your bump is not changing and lacks other symptoms, this may be less likely.

5. Molluscum Contagiosum: This is a viral infection that can cause small, raised bumps on the skin. They are usually painless and can resolve on their own, but they can spread through skin-to-skin contact.

6. Allergic Reactions or Irritation: Sometimes, bumps can arise from allergic reactions to soaps, lotions, or other products. If you have recently changed any personal care products, this could be a potential cause.

7. Hormonal Changes: Hormonal fluctuations can lead to various skin changes, including the development of bumps or cysts. This is particularly relevant if you have experienced any recent changes in your menstrual cycle or hormonal treatments.

Given that your bump has not changed in size, is not painful, and is not associated with other symptoms, it may not be a cause for immediate concern. However, it is essential to monitor the bump for any changes in size, color, or associated symptoms such as pain or discharge.
If the bump persists or if you develop any new symptoms, it would be wise to consult a healthcare provider for a thorough evaluation. They may perform a physical examination and, if necessary, recommend further testing to determine the exact nature of the bump.
In summary, while there are several benign explanations for a labial bump, it is always best to err on the side of caution and seek medical advice if you have any concerns. Regular gynecological check-ups are also important for maintaining reproductive health and addressing any issues that may arise.
