What is the cause of black mole on vulva

If a black mole grows on the vulva skin, you must pay attention to it. There are many reasons for melanin, which is related to the excessive growth of pigment cells. For example, if the vulva is squeezed, rubbed or irritated for a long time, it may become malignant. Therefore, if this kind of vulva melanin appears, you must pay attention to it and go to the hospital for examination and regular treatment in time.

Clinical manifestations

There are often no subjective symptoms. Flat or raised light brown to black moles can be seen on the vulva, usually 1 to 2 mm in diameter, and sometimes with hair on the surface. If the color of a pigmented nevus suddenly deepens, the nevus enlarges, the surrounding area becomes red, ulcerated, or bleeds, and the patient feels itchy and painful, then there is a possibility of malignancy. The diagnosis can be confirmed by biopsy.

What is melanoma?

In this regard, the doctor carefully explained that moles are relatively common on the human body, and many people do not take the melanin moles on their bodies seriously, thinking that there is nothing to worry about. In fact, most melanin moles do not pose a threat to people's health, but a few melanin moles have the possibility of becoming malignant. Especially moles on the female vulva should be paid special attention to, because they may become malignant at any time.

Women's vulvar pigmented nevi are divided into two types: black nevi and blue nevi.

The reason why we need to pay enough attention to it is that vulvar nevus may develop into malignant melanoma, which has a high mortality rate. In addition, melanocytic nevi can be divided into light brown, dark brown and pure black, with a diameter between 1mm-2cm. Some are within the skin, some are raised on the skin, and some are nipple-like or wart-like protruding from the skin. The surface of the mole may have hair or be hairless. Blue nevi often grow on women's faces and forearms, most commonly on the back of the hands and rarely on the outer sides of the hands.

What to do if there is a black mole on the vulva

Female vulvar nevus is a pigmented nevus formed by excessive growth of pigment cells in the vulvar skin. Due to its special location, the vulva is subjected to long-term stimulation or friction, which may cause local pain, itching, bleeding or inflammatory reactions. At the same time, pigmented nevi are extremely sensitive to sex hormones and often increase in size and darken during puberty or pregnancy. According to relevant research statistics, nearly 80% of malignant melanomas occur in pigmented nevi.

Therefore, if female friends find that the color of a pigmented mole suddenly darkens, the location becomes lighter or changes radially, the area increases, and even redness, itching, ulceration and bleeding appear around it, they should be alert to the possibility of malignant transformation into malignant melanoma. Malignant melanoma has fast-growing tumors, high malignancy, and is prone to early metastasis. Therefore, for pigmented moles growing on the easily irritated parts of the vulva of women, doctors will recommend complete removal and sending them for pathological examination.
