Vulvar erysipelas

Introduction to vulvar erysipelas Vulvar erysipelas is an acute and chronic inflammation of the superficial lymphatic network in the vulvar skin mucosa caused by group A B-type hemolytic streptococcus and occasionally by type C or type G streptococcus. Vulvar skin mucosa is damaged, bacterial invasion induces vulvar erysipelas; it can also be caused by blood infection. Therefore, the severity of erysipelas is related to the susceptibility and immunity of patients. After the onset of the disease, the local skin color is bright red, and the boundary with the surrounding healthy tissue is clear, and generally does not purulent. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: vulvar rickets

Cause of vulvar erysipelas

(1) Causes of the disease

Any situation that reduces the body's resistance, such as chronic malnutrition, diabetes, uremia, etc., can be the cause of the disease. If the patient is weak and the immune function is low, the pathogen will be slightly scratched by the trauma of the vulva. , scratches, wounds will become a gap in the invasion of germs.

(two) pathogenesis

The pathogenic bacteria spread rapidly from the tiny lesions on the surface of the vulva and mucous membranes, and then spread rapidly, causing acute diffuse inflammation. The hemolytic streptococcal toxin can not only cause local redness and swelling, but also cause symptoms of systemic poisoning. The lesions are mainly located in the dermis and epidermis, the dermis is highly edematous, the blood vessels and lymphatic vessels are dilated, the inflammatory cells are infiltrated, and the edema may occur in the epidermis and even form bullae.

Vulvar erysipelas prevention

Active treatment of the primary disease is of great significance in preventing the occurrence of erysipelas.

Vulvar erysipelas complications Complications vulvar rickets

The infection continues to develop into a deep vulva edema.

Vulvar erysipelas symptoms Common symptoms Tensile chills, fatigue, sepsis, chills, erysipelas, appearance, vesicular inguinal lymph nodes, genital itching, nausea

Vulvar erysipelas is abrupt, often with aversion to cold, fever, headache, nausea, vomiting and other prodromal symptoms, and then a rash, the rash begins as a nodular erythema, rapidly spread to form a erythema around, clear boundary, local redness, Fever, pain, severe erythema touch on the surface of the skin burning, obvious tenderness of the surface tension, bilateral inguinal lymph nodes, tenderness, some patients can have large blisters or even gangrene, known as gangrenous erysipelas, some serious patients due to Bacterial spread and toxins can also cause visceral lesions and thrombosis, such as nephritis, myocarditis and cavernous sinus thrombosis. In addition, inflammation of the pleura, peritoneum, and meninges can occur, even death due to bronchial pneumonia and sepsis. The situation is common in elderly and frail patients and infants.

Vulvar erysipelas

Peripheral white blood cells increased significantly, neutrophils increased, pathogen culture and drug sensitivity test, severe cases of serum water and electrolytes.

Diagnosis and diagnosis of vulvar erysipelas

diagnosis

The erysipelas skin lesion is usually easy to diagnose. At the early stage of the disease, the local skin has a red-like erythematous erythema. The boundary is clear, the micro-lifting, accompanied by burning pain, and the acupressure area immediately fades. When the lesion expands to the periphery, the color of the central part begins to fade. Sometimes there are blisters or blood bubbles of varying sizes, often with chills, high fever, headache, fatigue and other systemic symptoms, and the lymph nodes in the affected area are often swollen.

Differential diagnosis

Vulvar erysipelas should be identified with the following diseases:

Bloated

The carbuncles occur on the outside of the labia majora. Around the hair follicles, the edema is rounded up above the surface of the skin. It is red, swollen, nodular, and varies in size. It begins to form a solid nodules, gradually becoming soft at the center, thinning the epidermis, and rupturing at the top. Pus.

2. Folliculitis

Folliculitis is red, swollen, and painful around the hair follicle. The conical swollen center has hair piercing.

3. Contact dermatitis

Contact dermatitis has a history of exposure to external irritants, mild systemic symptoms, and genital itching.

4. Cellulitis

Cellulitis is acute inflammation, the boundary of redness and swelling is unclear, and the central part is the most red and swollen. The inflammation is gradually reduced to the edge, the infiltration is deep, and the suppuration phenomenon is more obvious.
