Hairy labia minora

　　The etiology of hairy labia minora is not yet clear. Some believe that this condition is similar to penile珍珠疹, belonging to abnormal metaplasia, while others consider it to be caused by candidal infection, or possibly related to long-term chronic non-specific stimulation, but none of these have been confirmed.

　　Hairy labia minora is a benign papilloma, and its etiology is still unclear. Clinically, it often causes skin and mucosal itching, with the patient having a scratching habit. It can lead to vaginal infection due to skin and mucosal injury and unclean hand hygiene, exacerbating itching and possibly accompanied by abnormal discharge. Severe skin infection and injury can form vulvar ulcers that may not heal for a long time, so if the patient has明显 itching, they should pay attention to maintaining vulvar cleanliness, and can use a compound Kushen wash to clean the vulva, avoiding unnecessary concurrent infections caused by scratching.

　　Hairy labia minora generally do not cause any自觉 symptoms. They are more common in young women, and can occur in both unmarried and married individuals, with the age of onset mainly between 18-40 years, with an incidence rate of about 16%-18%. The clinical manifestations includeThe inner side of the labia minora has light red papules, about 1-2mm in size, showing a multiple, aggregated, granular appearance, merging into patches, and distributed symmetrically on both sides; another manifestation is the presence of绒毛状 projections, resembling carpet fluff. The patient. Commonly, there is white vaginal discharge resembling egg white, and the vulva occasionally has an itchy sensation. The etiology is not yet clear, and some propose it may be related to fungal infection; others believe it may be related to chronic non-specific stimulation or friction of the vulva leading to glandular hyperplasia. The clinical manifestations are distinct from those of condyloma acuminatum.

　　To prevent hirsutism of the labia minora, patients should maintain the cleanliness of the vulva in their daily life, often clean the vulva, urinate after sexual intercourse, and maintain personal hygiene and avoid multiple sexual partners to reduce the risk of infection.

　　Patients with hirsutism of the labia minora can undergo pathological examination and electron microscopy.

　　1. Histopathology

　　The histopathological examination shows mild thickening of the epidermis, papillary hyperplasia of the prickle cell layer to varying degrees, widening of the epidermal papillae extending into the dermis, obvious vacuolation in the superficial layer of the prickle cells, nuclei without deep staining, nuclear condensation and变性, no empty cells and viral particles. Basal cells, in addition to edema, are arranged normally. The dermal connective tissue proliferates, the blood vessels dilate, and inflammatory cells, mainly lymphocytes, infiltrate.

　　2. Electron microscopy

　　Electron microscopy shows a thin layer of incomplete keratinocytes on the surface of the epidermis, thickened cell membranes, disappearance of cell organelles in the cytoplasm, varying electron density of the matrix, nuclear condensation, and the superficial layer of the prickle cell layer often contains an unequal amount of glycogen cells. No empty cells and viral particles are seen. Basal cells sometimes present finger-like or branched cytoplasmic protrusions extending into the dermis, surrounded by a complete basement membrane, and the dermis contains inflammatory cells mainly consisting of lymphocytes.

　　There are no special dietary concerns for patients with hirsutism of the labia minora, and they can eat normally. Patients should pay attention to a balanced diet in their daily life, eat more fresh fruits and vegetables, and avoid spicy and刺激性 food.

　　Hirsutism of the labia minora has a self-limiting nature and can remain unchanged for a long time. If it is caused by secretion stimulation, inflammation (such as excessive leukorrhea), find the cause. Treat according to symptoms. If it is a developmental abnormality (physiological variation of reproductive organ mucosa), no treatment is needed. Laser treatment is prone to scarring, and it is better not to use it.
