1. Non infectious factors include irritation such as local trauma, friction, contraceptives, soap, and detergents. Local manifestations can include edematous erythema, erosion, exudation, and even bleeding. If secondary bacterial infection occurs, it can fester and form an ulcerated surface. The patient has significant pain and is unable to move. Clinically, it is called acute superficial balanitis.
2. Candida infection with candida is a kind of conditional pathogenic fungus, so candidal balanitis often secondary to diabetes. Elderly consumptive diseases, as well as a large number of antibiotics or hormones, can also be primary, which is mostly transmitted from the spouse's candida vaginitis. There may be reddish erosion and thin-walled pustules on the glans and coronary sulcus, but candida is often not found locally, which may be caused by local allergic reaction caused by candida.
3. Patients infected with amoeba protozoa often have foreskin balanitis lesions that partially lose their normal barrier function, and are subsequently caused by intestinal amoeba infection. Local erosion, ulcers, and tissue necrosis are evident. Amoeba can be found by direct smear of the secretion.
4. Trichomoniasis infection is most commonly caused by vaginal trichomoniasis in spouses. The symptoms are mild, mainly manifested as erythema, papules, and small blisters on the glans. The boundary is clear, the scope gradually expands, and patients often feel itching. Trichomonas can be found in the secretion.
In addition, there are still some cases where the etiology of balanitis is unclear, but the foreskin is too long, and the stimulation of foreskin scale is mostly related to the occurrence of balanitis. Therefore, men should also regularly wash their lower body to maintain local cleanliness and avoid irritation. If the foreskin is too long, circumcision can be performed after the inflammation is controlled.
