foreskin balanitis
Introduction
Introduction to foreskin balanitis Foreskin balanitis refers to inflammation of the inner skin of the foreskin and the head of the penis. A lipid substance secreted in the normal foreskin cavity. When the foreskin is too long or phimosis, such substances can accumulate into smegma to stimulate the foreskin and the penis head to cause foreskin balanitis. Foreskinitis caused by drug allergy is a delayed type of allergic reaction, which is quite common in clinical practice. It usually occurs 24 to 72 hours after eye drops. basic knowledge Sickness ratio: 0.05% Susceptible people: seen in men Mode of infection: non-infectious Complications: urethral stricture phimosis
Cause
The cause of foreskin balanitis
Physiological (45%):
The causes of this disease can be divided into two categories: first, simple or non-infectious factors; second, infectious or communicable diseases, the former, in addition to physiological phimosis, prepuce is too long, after sexual maturity, smegma stimulation or A small number of mechanical damage factors cause glans swelling, burning inflammation changes; the latter, unless the infection factor caused by foreskin balanitis belongs to, that is, pathogenic microorganisms are the leading factors caused by foreskin balanitis, which is bacterial and Fungal infections are the most common.
Infection (25%):
The pathogens of infectious male foreskin balanitis, except for a few toxin-producing bacteria (such as gonococcus), are mostly non-pathogenic microorganisms, or low-toxic bacteria often become pathogenic factors when conditions are available.
Pathogen (25%):
For the pathogenic bacteria causing foreskin balanitis, fungi, trichomonas or some anaerobic bacteria are most common. For patients suffering from foreskin balanitis, the source of such pathogenic bacteria is mostly caused by external sensation, that is, sex. It is passed on to the male with the bacteria and is ill with appropriate physical conditions.
Many conditional pathogens use female vagina as a breeding ground. They may affect the vaginal PH conditions due to the monthly endocrine changes of women, which is conducive to the active reproduction of such parasites, increasing the number, becoming a disease factor, causing local itching, burning, mucosal redness. , congestion, and even mucosal rash or erosion, followed by stimulation of vaginal secretions, microbial (fungal or trichomoniasis) product pseudomembrane forming flocculent leucorrhea, or foam-like secretion overflow, odor is increasing, in women During vaginal microbial reproduction, male and female sexual intercourse can easily become a chance for men to be infected, leading to the occurrence of foreskin balanitis. The infection may cause redness, rash, erosion, exudation and burning, and itching.
Prevention
Foreskin balanitis prevention
Prevention and care:
(1) Pay attention to local hygiene, clean the glans and foreskin daily, if the foreskin is too long to be treated in time, if necessary, for circumcision, it is necessary to clean the smegma in time.
(2) Couples suffering from sexual organ diseases should suspend sexual life, timely treatment, such as trichomoniasis or Candida albicans infection should be treated at the same time.
(3) Avoid unclean sexual intercourse and cleanse yourself.
Complication
Foreskin balanitis complications Complications, urethral stricture, phimosis
Secondary phimosis; urethral stricture; anterior urethra stricture.

Foreskinitis caused by drug allergy is a delayed type of allergic reaction, which is quite common in clinical practice. It usually occurs 24 to 72 hours after eye drops.
First, acute superficial balanitis: mostly due to underwear friction, trauma or soap, local irritant caused by detergent, edema, erythema, exudation, erosion, secondary infection with purulent secretions, easy to form ulcers, conscious pain.
Second, the ring erosive balanitis: the glans and foreskin inflammation damage is ring-shaped, or ring-shaped with cheese-like smegma, it is easy to break into shallow ulcers, and if it loses the ring characteristics, it is not easy to distinguish from superficial balanitis. The disease can exist alone or as a mucosal symptom of Reiter syndrome.
Third, plasma cell balanitis: more common in middle age, for single or multiple long-term chronic inflammation, the lesion is plaque-like, smooth surface or desquamation or moist, infiltration is more obvious, clear and not easy to collapse, The surface can be seen as tiny spots like paprika, and the shape is difficult to distinguish from the proliferative erythema of the glans.
If a similar lesion occurs in the female genital, it is called plasma cell vulvitis.
Histopathology is specific, a large number of plasma cells infiltrate in the dermis, telangiectasia, and hemosiderin deposition.
4. Mica-like and keratinized pseudoepithelial balanitis: The glans damage infiltrates hypertrophy, hyperkeratosis and mica-like molting, the affected area loses normal elasticity, shrinks over time, histopathology sees hyperkeratosis, and the acanthosis is thick. Epidermal extension is pseudoepithelial neoplasia.
Examine
Inspection of foreskin balanitis
Checking the test: Candida balanitis (the dermatitis) can be found in the lesion of the glans, the foreskin microscopic examination or culture can be found Candida, trichomonas balanitis can find trichomoniasis on the secretions.
Diagnosis
Diagnosis and differentiation of foreskin balanitis
Pay attention to the identification of other diseases:
(1) glans dermatitis begins to flush, erosive, but rarely blisters, may have exudate, foreskin edema can not be upturned, sometimes purulent secretions, according to different causes can be divided into traumatic balanitis, contact Balanitis, infectious balanitis, Candida balanitis, amoebic balanitis, trichomonas balanitis, plasma cell balanitis, etc.
(2) Hard sputum is a hard ulcer with neat edges. See syphilis for details.
(3) Gonorrhea can also occur glans dermatitis, but mainly manifested as acute suppurative urethritis.
(4) Fixed erythema drug eruption is often caused by oral sulfa drugs or analgesics, occurs in the genitals, has redness, often ulceration, erosion, and recurrence, and should be carefully asked about the medical history.
(5) Contact dermatitis.
(6) Herpes zoster.
(7) Impetigo and the like.
