flat wart
Introduction
Flat introduction FlatWart is a viral skin disease. Its pathogen, like common warts, is a skin mites caused by papillomavirus HPV3 and HPV5 infection. It is characterized by a dispersed distribution, a soft texture, a smooth top, a large miliary to mung bean, a light brown or a flat papule that rises above the surface of the skin. Occurs in the exposed parts of the face, back of the hand, etc., extremely easy to spread. basic knowledge The proportion of illness: 0.3% Susceptible people: people without special hair Mode of infection: contact spread Complications: skin cancer
Cause
Flat wart
Cause:
Caused by HPV 3,5,8,9,10,28,41,65, HPV spreads directly or indirectly to the host skin and mucosal epithelial cells, enters the cell through the contact of tiny erosion surface, and stays at the infected site. Epithelial cells replicate and transcribe, but do not enter the blood circulation, and do not produce viremia.
Prevention
Flat wart prevention
1. Keep away from ultraviolet light and ionizing radiation.
2. Keep away from traumatic treatments, such as ionization, laser, and autologous corpus callosum implantation. Such treatments tend to form "homotype reactions," which can cause scars that are difficult to remove and can aggravate the condition.
3. Stay away from hormonal drugs.
4. Drink plenty of water, eat more vegetables, fruits, and make fruit noodles.
5. Usually increase physical exercise, enhance immunity and prevent flat warts. To suffer from flat warts, be careful to avoid scratching the affected area and pay attention to reducing irritation. Do not have a lot of psychological pressure. Use appropriate methods to properly treat flat warts.
Complication
Flat wart complications Complications skin cancer
The disease is chronic, a small number of patients can resolve by one to two years or more, and the basal part of the sputum often has an inflammatory reaction before it subsides. The itching is aggravated, but it can recur. Very few patients may have cancerous changes, although The carcass is removed, but the effect is not good, which causes many patients with edema, ulcers, sputum and other complications.
Symptom
Flat wart symptoms common symptoms papules itching qi and blood loss
1, generally no symptoms, occasionally slightly itchy.
2, the skin lesions are cap-like to mung bean or slightly larger flat smooth papules, round, oval or polygonal, hard, normal skin color or light brown.
3, good for face, back and forearm.
The onset is more abrupt, the lesions are more normal skin, often scattered or densely distributed. The self-inoculation can be arranged in a beaded shape along the scratches due to scratching. The course of the disease is chronic, and it can be self-resolved. After leaving no traces.
Occurs in children and adolescents, also common in adults, often symmetrical in the face (cheek, sputum, forehead, ankle), the back of the hand and the forearm, etc., showing a normal skin tone or a round brown needle to the size of the lentils, Oval or irregular flat papules, smooth surface, hard, scattered or dense, can also be fused into small pieces, can be arranged in a bead-like arrangement (same-shaped reaction) (Figures 1-3), no symptoms, Itching often occurs before it subsides, the course of the disease is slow, it can last for 3 to 4 years, and it is self-limiting. It can heal itself in 1 to 2 years.

Examine
Flat wart inspection
1, blood routine, urine routine, fecal routine.
2, pathological examination.
3, humoral immunoassay: so-called humoral immunity (humoral inmunity), that is, the production of antibodies by B cells to achieve the immune mechanism of protection purposes. The cells responsible for humoral immunity are B cells. Most of the antigens for humoral immunity are proteins and polysaccharide macromolecules with a relative molecular mass of 10,000 or more. Viral particles and bacterial surfaces have different antigens, so they can cause humoral immunity.
Diagnosis
Flat wart diagnosis
It needs to be identified with the scorpion, which is a kind of skin surface neoplasm caused by human papillomavirus. More common in children and young people, the incubation period is 1 to 3 months, can spread by themselves. The virus is present in the acanthosis cells, which promotes cell proliferation and forms sickle lesions. According to clinical manifestations and locations, it is divided into vulgaris, flat warts, warts, genital warts (condyloma acuminata), oral warts, throat cramps and verrucous epidermal dysplasia.
