The inner side of the big penis has granules and it is very itchy

If there are granules on the inside of the labia majora and it is very itchy, it may be genital herpes. The virus that causes genital herpes is called herpes simplex virus. The virus can be divided into type 1 and type 2. The herpes simplex virus cannot survive outside the human body and must therefore rely on direct contact with the human body to spread. A detailed medical examination requires going to the hospital for diagnosis. This article describes the manifestations of vulvar skin diseases.

1. The lesions of vulvar skin diseases are the same as those of the skin in other parts of the body and can be divided into primary and secondary lesions. The former are lesions caused by pathological processes unique to skin diseases, including spots, patches, papules, plaques, wheals, nodules, blisters, bullae, pustules, capillary dilation or cysts; the latter are lesions caused by scratching, infection, treatment and repair on the basis of the primary disease, such as scales, maceration, erosion, ulcers, epidermal damage, scabs, scars, lichenification and atrophy.

2. The vulva is the opening of the vagina, urethra and various glands. Inflammatory lesions in the above parts can affect the vulva, especially the common candidal vaginitis and Trichomonas vaginitis in women, which are often complicated by corresponding vulvitis. Therefore, when lesions are found on the vulvar skin and mucous membranes, the presence of primary lesions in the vagina should be ruled out first. If the vulvar lesions are secondary, the primary lesions should be effectively treated first.

3. Vulvar skin diseases can occur alone or as part of systemic skin diseases. For example, vulvar psoriasis and vitiligo may appear on the skin of other parts of the body at the same time; in addition, vulvar skin diseases may also be local manifestations of systemic diseases.

4. The female vulva is the most hidden part of the body, and most people are reluctant to expose it easily. When symptoms of disease or discomfort occur, people often keep it a secret and let it run its course, which leads to delayed treatment. Therefore, any vulvar lesions should be treated by an experienced specialist as soon as possible.

5. Different vulvar lesions may be caused by the same skin disease, and the same vulvar lesions may be caused by different skin diseases. In particular, chronic vulvar skin diseases are more common than skin diseases in other parts of the body, and sometimes they cannot be diagnosed by physical examination alone. Therefore, a biopsy is necessary to improve the accuracy of diagnosis.

6. Many chronic vulvar skin diseases of unknown causes have a long course of illness, and various treatments are often difficult to achieve complete cure. Skin diseases are generally treated with topical medications, but in chronic skin diseases, the epidermis thickens at the lesions, and especially the presence of keratin in the cortex hinders and delays the penetration of drugs through the skin layer into the dermis where the itch nerve endings are located. Therefore, there is often no obvious effect in the early stages of medication. At this time, patients must be mentally prepared and cannot give up treatment.

Impetigo, also known as contagious pus crust rash, commonly known as "yellow blisters", is a common staphylococcal infectious skin disease.

Causes and pathogenesis

Most of the pathogens are Staphylococcus aureus, a few are Streptococci, and it can also be a mixed infection of the two. Some of these pathogens are nephritogenic. When the skin sweats a lot and is soaked, the skin's barrier function is destroyed and bacteria can easily multiply, creating a good opportunity for the disease to occur.

Clinical manifestations

The characteristics are the occurrence of papules, blisters or pus cells, which are easy to rupture and form pus scabs. It is transmitted through contact, spreads rapidly and can become prevalent among children.

1. Bullous impetigo

Caused by Staphylococcus aureus. It is highly contagious, more common in children, and more common in summer and autumn. Initially, it appears as scattered small blisters, which rapidly increase in size within 1-2 days, and the contents gradually become turbid, presenting as crescent-shaped pus accumulation. The typical lesions are thin-walled pustules, which quickly rupture to become erosive surfaces with honey-yellow scabs. It often occurs on exposed parts of the body, such as the face and limbs, and causes itching, but generally has no systemic symptoms.

2. Impetigo

Thin-walled blisters occur on the basis of erythema and quickly turn into pustules. After the blisters burst, the exudate forms a thick yellow crust, and adjacent skin lesions may fuse with each other. The patient will feel itchy, and scratching may spread the infection to other parts of the body, resulting in new rashes, which will not leave scars after healing. Severe cases are often complicated by systemic symptoms such as lymphadenitis and fever. This type often occurs on the face, around the mouth, around the nostrils, ears, and exposed parts of the limbs.

Impetigo can cause acute glomerulonephritis.

Clinical features

1. Cause: Mainly caused by Staphylococcus aureus and Streptococcus

2. Season of occurrence: Most common in summer and autumn

3. Prone groups: Children

4. Common areas: face, mouth, and around the nostrils

5. Characteristics of skin lesions: soybean-sized pustules distributed in groups, with thin walls that are easy to rupture, revealing red eroded surfaces. After the pus dries, honey-yellow scabs are formed, and there is a red halo around the pustules, which can merge with each other (Fig1).

6. Subjective symptoms: Itching in varying degrees.

7. Systemic symptoms: It may be accompanied by swelling of adjacent lymph nodes, fever, chills and other systemic symptoms. Can cause sepsis or nephritis.

8. Laboratory examination: White blood cells and neutrophils may increase. Bacterial culture was Staphylococcus aureus or hemolytic Streptococcus.

IX. Classification: Common type, Bullous type

Differential diagnosis: Varicella

〖Prevention and treatment〗

1. Pay attention to skin hygiene and take a bath frequently in summer. Isolate patients to prevent infection.

2. Local treatment: cleaning, anti-inflammatory, sterilization, drying and astringent. You can choose from Bactroban ointment, erythromycin, chloramphenicol ointment, gentian violet solution, etc.

If the skin lesions are widespread and the systemic symptoms are obvious, antibiotics and symptomatic treatment can be used.
