anal condyloma
Introduction
Anal genital warts Anal condyloma acuminata is a disease caused by the human papillomavirus that occurs at the junction of the anal and perianal skin and mucous membranes. It is often caused by contact with a virus-borne device or sexual contact infection. Mainly caused by HPV6, 11 and other types. Because certain HPV subtypes that cause condyloma acuminata are associated with the development of genital cancers such as cervical cancer, extra attention needs to be paid. For the cause of anal condyloma acuminata, it is generally believed that the intrinsic reason is that the patient's cellular immune function is reduced, and the external cause may be related to the wound being impervious, moist, susceptible to infection, and susceptible to frictional damage during walking and activity. The symptoms of anal HPV infection are not obvious. Sometimes, it can feel burning pain, itching and pressure in the perianal area. A few tiny reddish papules can be seen at the beginning of the condyloma around the anus. They gradually increase and increase, tend to merge or overlap each other. Cauliflower-like, papillary, scorpion-like or goose-shaped proliferation of varying sizes, soft in nature, and some of the skin lesions can be pedicled. Due to the infiltration of the secretions, the surface may be white, dirty gray, red or bleeding, with pus between the particles and a foul smell. basic knowledge The proportion of illness: 0.003% Susceptible people: no special people Mode of transmission: sexual transmission, contact transmission Complications: Chlamydia infection
Cause
Anal condyloma
For the cause of anal condyloma acuminata, it is generally believed that the intrinsic reason is that the patient's cellular immune function is reduced, and the external cause may be related to the wound being impervious, moist, susceptible to infection, and susceptible to frictional damage during walking and activity. Specifically, the causes of anal condyloma acuminata are:
Self factor (30%):
Self-infection, laser can cause self-infection, vulvar, perineal and other condyloma acuminata, after laser treatment, some people will relapse in the perianal, such patients account for one-third of all perianal patients.
Indirect factor (30%):
Indirect infections, they may be related to the use of some hygiene products or infections in saunas, baths, etc., which account for one-third.
Direct factor (30%):
Direct sexual contact, including anal sex or non-anal sex, accounts for one-third of these patients.
Prevention
Anal condyloma acuminata prevention
1. Stop anal sex and sexual behavior.
2. Avoid unclean sex and cleanse yourself.
3. In addition to prevent indirect infections, it is recommended not to use public towels, bath towels, or bathing in a shared bathtub.
Complication
Anal condyloma Complications Chlamydia infection
Can be complicated by malignant lesions, chlamydia infection.
Symptom
Anal condyloma acumin symptoms Common symptoms Anal skin flushing pimples wet anal itching anal eczema itching itchy sable nodules
The symptoms of anal HPV infection are not obvious. Sometimes, it can feel burning pain, itching and pressure in the perianal area. A few tiny reddish papules can be seen at the beginning of the condyloma around the anus. They gradually increase and increase, tend to merge or overlap each other. Cauliflower-like, papillary, scorpion-like or goose-shaped proliferation of varying sizes, soft in nature, and some of the skin lesions can be pedicled. Due to the infiltration of the secretions, the surface may be white, dirty gray, red or bleeding, with pus between the particles and a foul smell. Due to local scratching and friction, the carcass can be damaged and the surface is eroded, and exudate, hemorrhage and secondary infection occur, and the growth of the carcass is particularly obvious. Most pimples at the beginning, and then grow like a scorpion, can be large pedunculate cauliflower, more plaque piles with flat, small papillary surface, due to secondary infection, secretions are often unpleasant Stinky.
Examine
Anal condyloma
1. Pathological biopsy: take a piece of suspected tissue and perform staining treatment to find the hollowed out cells at high magnification.
2, immunohistological examination: commonly used peroxidase anti-peroxidase method (PAP), showing the viral protein in the wet sputum to prove that there is a viral antigen in the sputum damage. When the HPV protein is positive, a pale red weak positive reaction may occur in superficial epithelial cells of condyloma acuminata.
3. Histochemical examination: A small amount of diseased tissue was taken to make a smear, and stained with an antibody specific for human papillomavirus. If there is a viral antigen in the lesion, the antigen and antibody bind. In the peroxidase antiperoxidase (PAP) method, the core can be stained red. This method is specific and rapid, and is helpful for diagnosis.
Diagnosis
Diagnosis and identification of anal condyloma acuminata
diagnosis
The diagnosis was based on his medical history, clinical manifestations, signs, and acetic acid white test. All cases were confirmed by pathological examination.
The diagnosis of rickets needs to be judged according to the patient's symptoms and specific examinations. The common diagnosis basis includes:
1. Have had unclean sex in the past six months;
2. The anal and genitals have large tumor-like growth organisms;
3. The growth of the diseased part is cauliflower-like, cockscomb-like, thorn-like, nipple-like appearance, uneven surface, oppressive or foul-smelling;
4. There will be genital itching and discomfort, and patients may have difficulty in urinary blood and dysuria;
5. There are symptoms such as pain, blood in the stool, and urgency in the rectum.
If the patient has one or more of the above symptoms, you should consider whether you have an anal fistula.
Differential diagnosis :
Flat genital warts: For the deposition of multiple wet papules into flaky skin lesions, more common in the perianal area, syphilis can be found in the lesions, syphilis serum test was positive.
