vulvar soft fibroma
Introduction
Introduction to vulvar fibroma Vulvar fibroma is a benign polyp mass covered by a squamous epithelium with fibrous blood vessels as the core. It is often small and soft. It is a kind of benign tumor with pedicle. It grows in the skin part of the labia majora. It is sesame grain or rice grain size, light brown or dark brown, and is usually multiple. basic knowledge The proportion of illness: 0.005% Susceptible people: women Mode of infection: non-infectious Complications: vaginitis
Cause
Causes of vulvar fibroma
Cause
Vulvar fibroids are neoplasms formed by the loose connective tissue protruding outward from the surface of the skin.
Pathogenesis
The vulvar soft fibroma has a spherical shape with a diameter of 1 to 2 cm. It can be pedicled, the surface of the tumor is wrinkled, the tumor is soft and polypoid, and the cut surface is white soft fibrous connective tissue. The characteristics of the microscopic epithelium are obvious in the vulva. The composition of the fibrovascular interstitial, the surface is covered with a relatively normal or atrophic squamous epithelium, papillary hyperplasia and hyperkeratosis may also occur. In different cases, the mesenchymal components may vary greatly, and some cellular components are sparse. In the loose mucus edema-like interstitial, the cells are gently shaped, some cases are rich in cells, there is no boundary zone between the epidermis, the cells are pleomorphic, there are a large number of exotic large cells and multinucleated cells, and there may be Significantly increased mitotic figures, immunohistochemical staining desmin, vimentin positive, actin partial positive, ER and PR interstitial cells can be positive.
Prevention
Vulvar fibroma prevention
1, regular physical examination: to achieve early detection, early diagnosis, early treatment.
2, good follow-up: to prevent the disease from getting worse.
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 fibroma complications Complications vaginitis
Infection of vulvar fibroids can spread and vaginitis.
Symptom
Vulvar fibroma symptoms Common symptoms Vulvar damage wet polyps
Vulvar fibroma lesions occur mostly in the labia majora, single or multiple, clinically asymptomatic, patients found in palpation or observation, visible tumors are round, polypoid, often pedicle, more surface folds Some can be similar to genital warts, can be stored for many years, very few will form a large soft fibroids, when the blood supply is insufficient, ulcers can occur, symptoms appear when the pedicle is twisted or broken, mainly pain, ulceration Broken, bleeding and infection, sometimes the mass is rubbed and discomfort, the smaller soft cocoon is similar to the dermis, from the isolated hard collagen, and may also have polypoid vulvar damage.
Examine
Examination of vulvar fibroids
Routine examination of vaginal secretions, examination of tumor markers.
Histopathological examination.
Diagnosis
Diagnosis and diagnosis of vulvar fibroma
diagnosis
The clinical features of vulvar fibroids are significant, the diagnosis is not difficult, and pathological biopsy can confirm the diagnosis.
Differential diagnosis
Vulvar fibroma needs to be differentiated from the following diseases:
1. Fibroids (hard fibroids): fibrous tissue that generally originates from the deep part of the perineum or round ligament. The interstitial is generally denser and has more collagen fibers.
2. Condyloma acuminata: There are hollowed out cells and branched nipples.
3. Neurofibromatosis: more abundant in cells, S-100 positive.
4. Invasive angiomyxoma: no polypoid, invasive growth in deep tissue, abundant blood vessels (including medium to large blood vessels), diffuse distribution, visible smooth muscle cell lines.
5. Vascular myofibroblastoma: It is usually a well-defined, non-polypoid mass, and spindle cells and plasmacytoid cells are arranged around thin capillary capillaries.
6. Superficial vascular myxoma: Both can be polypoid growth, but the superficial vascular myxoma lesions are multinodular, rich in mucus matrix and neutrophil infiltration, but no multinucleated interstitial cells.
7. Cellular angiofibroma: a non-polypoid-like tumor with clear boundaries, mild cells, lack of multinucleated cells and uniform blood vessels.
8. Leiomyoma: usually not polypoid, there is a boundary between spindle cells and epidermis.
9. Vulvar papilloma: It is easier to identify under the microscope.
