Is the hard lump under the vulva that does not hurt or itch a tumor?

The female vulva can be said to be a very magical part. The reason for this is mainly because the female vulva is indeed too easy to be hurt, but its own repair ability is also very strong. For example, some women suffer from vulvar tearing in daily life. Of course, if it is not serious, they can recover slowly without treatment. So, is the hard lump under the vulva that does not hurt or itch a tumor?

Causes

1. Vulvar infection

Such as sexually transmitted diseases, viruses, bacteria, Trichomonas, fungi, etc., and vulvitis caused by menstruation. The vulva is the primary and most common site of onset.

2. Mechanical Stimulation

Such as bad hygiene habits, dirt on the vulva, tight underwear, irritation from sweat, etc.

3. Allergic vulvitis

Allergic dermatitis caused by detergents, cosmetics, condoms and medicines.

4. Foreign objects in the vagina

Long-term placement of a pessary or foreign matter remaining in the vagina may cause infection and irritation of the vulva, resulting in swelling and pain.

5. Irritation from urine and feces

Urinary diseases, feces, and diabetes mellitus patients' sugar stimulation.

6. Systemic diseases

Diabetes, systemic lupus erythematosus, papular psoriasis, etc.

7. Vulvar malignancy

Vulvar cancer, vaginal cancer, etc.

8. Vulvar Bartholin's gland abscess

9. Unexplained vulvar pain

Vulvar vestibule swelling and pain accompanied by frequent urination, urgency, and diabetic syndrome, the pathogenesis of which is unclear.

10. Post-traumatic hematoma

It can also cause more severe swelling and pain.

Clinical manifestations

1. Early Signals

(1) Leukoplakia: There are tiny, smooth white spots or stripes on the vulva, which later merge into thick, shiny milky white spots that feel hard and rough to the touch.

(2) Nodules: There are soybean-sized nodules or nipple-like tumors on the vulva, accompanied by itching around them.

(3) Ulcers: If a sunken, hard-bottomed ulcer appears on the female vulva that does not heal for a long time and is accompanied by pain and bleeding, it is often a sign of female vulvar cancer.

(4) After excluding candidal infection, pubic lice, scabies, vaginal trichomoniasis and other causes of female vulvar pruritus, if the vulvar pruritus does not heal for a long time and the cause cannot be found, and the itching is stubborn and severe, female vulvar cancer should be considered.

2. Benign tumors

Benign vulvar tumors are rare and include papilloma, fibroma, lipoma, sweat adenoma, etc.

(1) Papilloma often occurs as a single lump on the labia majora or mons pubis, with fine and dense nipples on the surface and a slightly hard texture. The rate of malignant transformation is high.

(2) Fibroma usually occurs as a single hard nodule on the labia majora, which gradually grows into a solid tumor with a pedicle.

(3) Lipomas arise from the fat layer of the mons pubis and labia. They vary in size, grow slowly, and are relatively soft. It is generally asymptomatic and the possibility of malignant transformation is low. However, due to its large size, it may cause mobility problems or difficulty in sexual intercourse.

(4) Sweat adenoma arises from the apocrine sweat glands of the labia majora and perineum and is generally 1 to 2 cm in size. The tumor grows slowly and causes no symptoms. A few may become cancerous.

3. Malignant tumors

Vulvar squamous cell carcinoma is the most common vulvar malignancy, with an average age of onset of 60 years. It often occurs on the labia, clitoris and perineum. The cause of the disease is still unclear, but it has a high coexistence rate with sexually transmitted diseases (such as genital warts, gonorrhea, syphilis and trichomoniasis); it develops into invasive cancer from viral infection (human papillomavirus); it is related to the body's immune function being low or damaged, such as after kidney transplantation, lupus erythematosus, etc.; vulvar dystrophy and vulvar warts can both develop into vulvar squamous cell carcinoma.

In the early stage, small and hard nodules, lumps or ulcers appear locally, often accompanied by pain or itching; in the late stage, there are typical erosions, lumps or irregular papillomas, which may be white, gray, pink or have melanin deposition in color, and unilateral or bilateral inguinal lymph nodes are enlarged, hard and fixed. When the tumor ruptures or becomes infected, symptoms such as frequent urination, painful urination, difficulty urinating, and difficulty defecation may occur. However, most patients have a history of vulvar itching for many years before the onset of the disease, which is more severe at night; white lesions on the vulva, etc.
