vulvar leiomyoma

Introduction

Introduction to vulvar leiomyomas Vulvarleiomyoma is a benign tumor of the skin composed of smooth muscle cells. If the fibroids are small, it can be free of any symptoms. If the tumor is too large, it will cause a vulva fall, and even affect activities and sex. basic knowledge The proportion of illness: 0.0085% Susceptible people: women Mode of infection: non-infectious Complications: sarcoma

Cause

Causes of vulvar leiomyomas

(1) Causes of the disease

Vulvar leiomyomas are derived from vulvar erectile smooth muscle or round ligament smooth muscle.

(two) pathogenesis

Tumors vary in size. The literature reports that leiomyomas are 1 to 11 cm in diameter. They are hard and have a capsule. The texture depends on the amount of fibrous tissue and the presence or absence of degeneration. It is usually single and is located under the skin of the labia or labia. The basal is broad and pedunculated, movable, and the tumor size is different. The cut surface is a solid tumor. Under the microscope, the spindle-shaped smooth muscle cells are criss-crossed, parallel or spiral, and the size and shape of the nucleus are basically the same. There is fibrous interstitial between the bundles, the cytoplasm is eosin, the blunt ends are dumbbell-shaped, the muscle fiber bundles are closely arranged, grayish white with luster, occasionally visible hemorrhagic necrosis, during pregnancy, vulva Leiomyoma is particularly prone to mucoid degeneration.

Pathology can be divided into cell-rich, epithelioid, schwannoid-like and syncytial cell types, of which epithelial leiomyoma is invasive and recurring, often accompanied by degeneration.

Prevention

Vulvar leiomyomas prevention

1, regular physical examination: to achieve early detection, early diagnosis, early treatment.

2, good follow-up: to prevent vulvar sarcoma sarcoma.

3, pay attention to personal hygiene, especially the health of the genitals during menstruation and puerperium.

4, enhance physical fitness, improve their own immunity: pay attention to work and rest, more to participate in physical exercise, eat more fresh fruits and vegetables rich in vitamins.

Complication

Vulvar leiomyomas complications Complications sarcoma

There is a possibility of complicated sarcoma.

Symptom

Symptoms of vulvar leiomyomas Common symptoms Sexual intercourse difficulty vulvar swelling shame area mass nodule vulva falling feeling

The patient generally has no discomfort, sometimes feels the vulva falling, and some patients see the doctor because of the genital mass. The most common part is the labia majora. The clitoris and labia minora also have a disease. The surface is smooth and hard, protruding from the vulva skin surface or A pedicle-like twin, gynecological examination revealed a substantial mass in the vulva, with clear boundaries, can be promoted, and no tenderness.

There are two forms of clinical: one is a nodule that is hidden in the tissue, and often has no symptoms. Only the patient feels that there is a small lumps in the local faint; the other type is pedicled or protruding from the surface of the skin. Blocks, difficult sexual intercourse, inconvenient movements, etc., the literature reports that the largest fibroids of the genitals can reach 10cm in diameter.

Examine

Examination of vulvar leiomyomas

Secretory examination, cervical cytology, and tumor marker examination.

Histopathological examination.

Diagnosis

Diagnosis and differentiation of vulvar leiomyomas

diagnosis

The diagnosis of fibroids in the vulva is relatively easy. It is mainly found according to its local manifestations and pathological examinations. It is important to exclude sarcoma, and the sarcoma of the genital fibroids is related to the following factors:

1. The size of fibroids: The fibroids of the vulva are generally small, and the diameter rarely exceeds 5 cm. According to Tavassoli, the diameter of the fibroids exceeds 5 cm, and the chance of sarcoma becoming or recurring is more.

2. Whether the contour of the fibroids is clear: If the pseudo-envelope around the fibroids is clear, there is not much chance of malignant transformation. On the contrary, there is infiltration around, and the fibroid boundary is unclear, so the chance of malignant transformation increases.

3. Frequency of nuclear division: The more cell division, the greater the chance of malignant transformation. If there are more than 5 divisions in 10 high power fields, it can be confirmed as sarcoma.

4. The degree of rich cells: rich cells do not represent malignant transformation of fibroids, but can indicate active cell proliferation, can be said to be a precursor change in sarcoma, must be treated with caution.

Differential diagnosis

1. Vulvar fibroids: The morphology of vulvar fibroids and vulvar leiomyomas is similar, the texture is hard and easy to move, and can be diagnosed according to pathological examination.

2. Vulvar granulosa cell myoblastoma: The tumor is a hard nodule with no obvious capsule. The tumor cells are round or polygonal, containing eosinophilic particles.

3. Vulvar leiomyosarcoma: vulvar leiomyomas grow rapidly in a short period of time, the border of fibroids is blurred, the activity is poor, and the sarcoma may be vigilant, which should be taken seriously.
