Berenson Red spots on the glans but painless itching may be caused by balanitis, allergic reactions, friction irritation, eczema or psoriasis, etc., and can be improved through local cleaning, anti-allergic treatment, drug treatment, etc.
1. Balanitis
Balanitis can be caused by a bacterial or fungal infection and is common in men with an excessively long foreskin. Patients may develop erythema accompanied by white discharge, but in some cases there is no obvious discomfort. You can wash the area with warm water every day and use erythromycin ointment or clotrimazole cream as directed by your doctor. If recurrence occurs, systemic diseases such as diabetes need to be investigated.
2. Allergic reaction
Contact with chemicals such as condoms and detergents may cause contact dermatitis, which manifests as well-defined erythema, usually without itching. It is recommended to stop using suspected allergenic products and apply hydrocortisone cream for a short period after rinsing with water. Parents should be aware that children may have allergic reactions to the material of diapers.
3. Friction stimulation
Friction from clothing or excessive cleaning can lead to mechanical erythema, which is characterized by a regular shape and symmetrical distribution. Most of the symptoms will subside on their own after changing to pure cotton underwear and avoiding the use of alkaline soap. Transient erythema that occurs after strenuous exercise does not require special treatment.
4. Eczema
Chronic eczema can appear as dark red patches on the perineum with dry and flaky surfaces. It may be related to mental stress or immune dysfunction. In addition to using hydrocortisone butyrate cream, the affected area needs to be kept breathable and dry, and the bath water temperature should not be too high.
5. Psoriasis
When psoriasis vulgaris involves the glans, it presents as red infiltrative plaques with clear borders and silvery white scales. A dermatologist will need to make a diagnosis and develop a long-term treatment plan, which may include drugs such as calcipotriol ointment. Such patients need to pay attention to quitting smoking, limiting alcohol, and controlling triggering factors.
You should pay attention to cleaning the perineum every day, choose cleaning products without allergenic ingredients, and avoid wearing tight chemical fiber underwear. If the erythema lasts for more than 2 weeks or if exudation or ulcer occurs, seek medical attention as soon as possible to rule out special skin diseases such as lichen planus. Clean and protect yourself before and after sex. If your spouse has vaginitis, you should treat it together. Diabetic patients need to strictly control blood sugar to reduce the risk of infection.
