Pigmentation on the Vulva: Is It a Mole? - Obstetrics and Gynecology

Pigmentation of the genital organs?


I accidentally found a smooth, flat pigmented lesion approximately 1 x 2 mm in size on the inner side of the labia, which is red and has a black or gray color.
Is this a mole? Does it have any significance? Will it affect sexual activity? Thank you.

It is not possible to diagnose your condition based on your description; it is advisable to visit an outpatient clinic for examination and, if necessary, a biopsy.
As for whether it affects your sex life, that is a subjective matter between you and your partner, and I will not comment on it.

When it comes to pigmentation on the vulva, particularly a smooth, flat lesion measuring approximately 1 x 2 mm that appears black or gray, it is essential to approach the situation with caution and a thorough understanding of the potential implications. While it is possible that this could be a mole (or nevus), there are several factors to consider before jumping to conclusions.

Firstly, moles can vary significantly in appearance, size, and color. A typical mole is usually brown or black, but they can also be gray or even skin-colored. The smooth surface you describe is not uncommon for a benign mole. However, the presence of pigmentation in the genital area can also be due to other conditions, including benign hyperpigmentation, seborrheic keratosis, or even more serious conditions like melanoma, especially if there are changes in color, size, or shape over time.

In terms of sexual activity, the presence of a benign mole or pigmentation typically does not affect sexual function or health. However, if the lesion is symptomatic—causing pain, itching, or bleeding—it is advisable to seek medical attention. Additionally, if there are any concerns about the nature of the pigmentation, such as changes in appearance or new symptoms, it is crucial to consult a healthcare provider for a proper evaluation.

It is also important to note that any new or changing skin lesion should be assessed by a healthcare professional, particularly a dermatologist or gynecologist. They may perform a physical examination and, if necessary, a biopsy to determine the nature of the lesion. This is especially true if there is any suspicion of malignancy, as early detection is key in managing skin cancers effectively.

In summary, while the pigmentation you describe could potentially be a benign mole, it is essential to have it evaluated by a healthcare professional to rule out any serious conditions. Regular self-examinations and awareness of changes in your body are crucial for maintaining health, particularly in sensitive areas like the vulva. If you have any concerns about your sexual health or the impact of such lesions on your sexual activity, do not hesitate to discuss these with your healthcare provider. They can provide personalized advice and reassurance based on your specific situation.
